A device for sensing electrical power drawn through a circuit having a circuit breaking device in a power line, comprises sensing means, for sensing power being drawn through the circuit breaking device and generating one or more signals indicative of the power being drawn, and a contact configured to be inserted into the circuit breaking device for sensing the power being drawn there-through.
Description
POWER SENSOR
Field of the Invention
The present invention relates to a power sensor such as a sensor which is adapted for use with a circuit breaking device to sense power drawn there-through.
Background of the Invention
In recent years, increased concern over environmental issues has led to a demand for technologies which promote the reduction of the consumption of energy. An important aspect in this area involves raising awareness of the amount of energy being used by particular appliances. Not only does providing a consumer with information regarding energy used by particular appliances help to encourage a reduction in waste, it is also helpful in indicating the relative cost of appliances in terms of their energy consumption.
Typically, electricity consumption in residential and commercial buildings is monitored by an electricity meter which measures the total number of units of electricity used by a particular household over a given period of time. Generally, a household or a business premises will receive a bill detailing the total amount of electricity consumed, and the cost of that electricity being charged, every quarter. This infrequency of information makes it very difficult for a consumer to regulate the amount of electricity being used and impossible to make targeted reductions in usage of high power appliances.
Consequently, the consumer remains unaware of how best to reduce his or her consumption of energy.
Recently, smart metering technologies have been developed which provide real time information regarding the total amount of energy consumption at a particular time.
Thus, a consumer is able to identify how much electricity is being consumed throughout the household at a given time and attempt to reduce that consumption based on his or her knowledge of the appliances being used.
However, smart metenng technology provides little or no information about which appliances are consuming the most energy, or where in a building the most energy is being consumed. Without resorting to trial and error, a consumer is unable to make informed decisions about how best to reduce his or her energy consumption, such as by turning off only the high power appliances located in certain areas, and thus fails to do so.
Every household or business premises or the like typically includes a fuse box, switchgear enclosure or distribution panel or equivalent electricity distribution point.
These boxes hold a series of fuses or circuit breakers, for a plurality of circuits around the building. For example, in a household, it is usual for the lights and other appliances to be on separate circuits depending on their location in the building. Often, all lights in a particular area will be on a first circuit whereas all of the appliances in that area will be on a second circuit.
By rneasunng the power drawn on a particular circuit, it is possible to provide the consumer with information regarding where in the building, and optionally when, the energy consumption is highest. The consumer is then able to make an informed decision about how best to reduce his or her electricity consumption depending on the consumer's preferences It is well known to monitor the power of electrical circuits. For example, it is known to use shunts in electrical circuits. Shunts comprise known resistances which are placed within a circuit in series with the load. The voltage drop is measured across the shunt and the level of voltage drop, along with the known resistance, allows the current flowing through the shunt to be calculated. Once the current is known, power may be calculated in accordance with methods familiar to those skilled in the art.
However, shunts and similar components can be bulky, inconvenient to install and they also involve cutting into a cable. Thus it is difficult to implement such solutions into existing circuits to measure the power being drawn through particular appliances or circuits.
Summary of Invention
Accordingly, the present invention provides a device for sensing power drawn through a circuit having a circuit breaking device in a power line.
Henceforth, where the expression "circuit breaking device" is used, this is intended to include any device which is adapted to break a circuit automatically when a certain power leveJ is breached. Such devices specifically include one or more Rises, self resetting fuses and the like, disposed in one or more fuse boxes, fuse holders or fuse panels, for example, as well as any type of circuit breaker, miniature circuit breaker, moulded case circuit breaker, vacuum or air circuit breaker, or the like, disposed in a switchgear enclosure or distribution panel, for example.
The power sensor comprises sensing means for sensing power being drawn through the circuit breaking device and generating a signal indicative of the power being drawn through the circuit breaking device, and a contact configured to be inserted into the circuit breaking device for sensing the power being drawn there-through.
In the context of the application, the sensing means configured to sense power includes any means by which the presence or a particular quality of power being drawn may be identified. The signal indicative of the power corresponds to an indication of the presence or particular quality of the power.
In a preferred embodiment, the particular quality of the power is its amplitude which may he measured in accordance with techniques known in the art. In this embodiment, the sensing means comprises measuring means for measuring power being drawn through the circuit breaking device. In this embodiment, the signal indicative of the power being drawn comprises measurement data.
Whereas other known power measurement devices, such as shunts, require a circuit to be adapted to insert the shunt at the appropriate place (which can often involve cutting into a wire), the contact of the power sensor enables the sensor to be quickly and easily installed onto a circuit breaking device to measure power being drawn there-through without having to embark on a laborious installation procedure or cut any wires.
The power sensor also facilitates accurate and reliable power measurement because the pathway through which the power being measured is drawn has been preinstalled, and provides the power directly to the appliances through the sensing device.
Circuit breaking devices such as fuse boxes and circuit breakers arc typically of standard designs which include at least one aperture for accepting cables. The contact of the present invention may, for example, be configured to be insertable into such an aperture, but could also be inserted into any other aperture in the circuit breaking device.
Optionally, the contact is configured to be inserted into an output connection of the circuit breaking device.
Optionally, the power sensor comprises a switching relay for isolating the circuit breaking device from and connecting the circuit breaking device to the circuit.
Not only does the invention provide for a convenient module to be connected to the circuit breaking device to provide information to a consumer regarding power drawn there-through but, optionally, the invention provides a mechanism for connecting and disconnecting the circuit at the circuit breaking device to enable the cessation of power being delivered without having to switch off individual appliances.
In certain embodiments, the power sensor comprises a communication means for sending the signal indicative of the power being drawn, such as measurement data, for example, to a remote device. Optionally, the communication means further comprises a remote data processing unit communicatively coupled to the sensing means.
By communicating the signal generated at the power sensor to a remote device situated around the household, a consumer has access to power consumption measurements, or other information indicative of the power, at the source of consumption. Thus, the consumer is able to identify, for example, how much power is being drawn in a particular area, or by a particular appliance or group of appliances, without having to refer to the fuse box, switchgear enclosure or distribution panel or the electricity meter.
Preferably, the power sensor comprises an internal memory for storing the signal indicative of the power being drawn generated by the sensing means. In preferred embodiments, the internal memory is configured to store the measurement data.
The provision of an internal memory in the device allows for additional flexibility in the processing and communication of the signal or the measured data. The memory may H) help to buffer the signals or data prior to transmitting it to a receiver, for example.
Alternatively, the memory may allow previous signals or data to be retrieved upon request and ensure data integrity and secunty in the event of a communication failure.
The invention also provides a system comprising the sensing device described above 1 5 along with at least one remote device communicatively coupled to the sensing device.
The remote device may he communicatively coupled to the communication means of the sensing device either directly through the power line, via a cable extending from the communication means to the remote device, via wireless signalling, via infrared signalling or over a computer network.
Of particular benefit in the present invention is the optional disposal of the power sensor at the power line. This enables, in certain embodiments, communication of the generated signal directly through the power line to the remote device. In such embodiments, both the power sensor and the remote device are electrically connected to the power line.
The communication means and the remote device may form part of a computer network or may communicate to each other wirelessly. In such embodiments, the remote device may be a PDA, a local or networked computer or a digital TV, for example.
Furthermore, information provided by the power sensor may be displayed via the web for access at off-site locations.
In certain embodiments, the at least one remote device comprises a user interface for sending signals to and receiving signals from the sensing device.
Optionally, the user interface is communicatively coupled to the communication means and configured to display the signal indicative of the power being drawn. In preferred embodiments, the user interface is configured to display the measurement data.
In addition, the user interface may optionally be communicatively coupled to the switching relay and configured to generate signals to isolate the circuit breaking device from and connect the circuit breaker to the circuit.
A user interface, in communication with the device, enables the consumer to have access to information regarding the status and power consumption of a circuit in a particular area on a real time basis. This information allows the consumer to exercise a greater degree of control over power consumption. For example, by having access to this information, or access to a switching relay for disconnecting the circuit, or both, the consumer may make, and then act on, informed decisions regarding electricity usage.
The consumer may also deploy automated routines for disconnecting various appliances or circuits individually or collectively according to preference or predetermined logic.
Previously, such infbrmation was difficult and time consuming to obtain manually and isolation of circuits had to be done at the fuse box, switchgear enclosure or distribution panel.

Detailed Description of the Drawings
Figures 1 to 3 illustrate an embodiment of a power sensor 10 according to the present invention. As shown, the power sensor 10 is a unitary device, preferably comprising a housing 12 constructed from two plastic interconnecting sections. The two sections are moulded using a standard plastic moulding technique such as injection moulding. Of course, plastic is merely optional and other suitable materials may also be used, as required.
The power sensor 10 optionally comprises a screw 14 engaged through the housing 10.
The screw 14 serves to hold the power sensor 10 in a desired position on a fuse box, switchgear enclosure or distribution panel, fhr example.
The power sensor 10 comprises a clip 16 disposed on the top surface of the housing 12.
The clip 16 improves the handling of the power sensor 10 and, in certain embodiments, protects wires 1 8 from accidental damage.
The power sensor 1 0 comprises a contact 20, which preferably extends from the base of the housing 12. The contact 20 is preferably constructed from an electrically conductive metal, although other suitable conductors may be used. Preferably the metal is copper, but any suitable conductive metal may be used.
The contact 20 is configured to be inserted into a circuit breaking device such as a fuse box or a circuit breaker. As described above, other embodiments of the invention may be configured for insertion into any type of circuit breaking device. Typically, circuit breaking devices such as fuse boxes and circuit breakers compnse apertures, known as output connections, which receive external connections. The contact may be inserted into such an aperture quickly and easily without the need to interrupt existing circuitry or cut any wires.
The housing 12 is adapted to be fitted onto a circuit breaking device for securement thereto. As the power sensor 10 is fitted, the contact 20 is inserted into the aperture.
Figure 4 shows two power sensors in accordance with that depicted in Figure 1 to 3 fitted onto circuit breakers in a household electricity distribution point.
The power sensor 10 is compact and easy to install into a fuse box, switchgear enclosure or distribution panel. In a preferred embodiment the width of the housing is substantially the same width as the circuit breaking device on which the sensor 10 is fitted.
Once fitted onto a circuit breaking device, with the contact inserted within the output connectors thereof, the power sensor 10 is capable of measuring the power drawn through the circuit breaking device using measuring means. In the first embodiment the measuring means are a current transformer (not shown) which is configured to measure the current drawn through the circuit breaking device and as well known in the art.
Of course, alternative power measurement technologies may be used in the power sensor in place of the current transformer.
The power sensor I 0 further compnses a switching relay (not shown). The switching relay is configured to connect and disconnect the circuit breaking device from the circuit in which the circuit breaking device is provided to connect and disconnect the mains power. When the switching relay is closed, the circuit is complete and electricity may flow through the circuit breaking device and the circuit to provide power to connected appliances. When the switching relay is open, the circuit is broken and no power may be provided to the appliances. Such switching relays are well known in the art, as are equivalent devices which could equally be employed in this invention for the same purpose.
Figure 5 illustrates a first embodiment of a system according to the present invention.
The power sensor 1 0 is in accordance with that illustrated in Figures 1 to 3 and further composes communication means 22. The communication means comprise an external remote data processing unit 24 provided outside of the power sensor 10. The remote data processing unit 24 communicates with the measuring means 26 inside the housing of the power sensor 22 by means of wires 28.
The remote data processing unit 24 comprises an internal memory 30 for storing data received from the measuring means 26. The processing unit 24 further comprises a processor 32 and is configured to process the data received from the measuring means 26 for communicating to at least one remote device 34 accessible by a consumer.
in the first embodiment, shown in the Figure 5, the communication means 22 communicate the processed data to the at least one remote device 34 by means of a wireless signalling device 36. The remote device 34 may be a PDA, a local or networked computer or a bespoke display panel accessible by the consumer.
Of course, wireless means are merely optional and other signalling means, including signalling directly through the power line, or using infra-red signalling, or communication via a computer network are also possible, as described below.
Furthermore, the use of a remote data processing unit is merely optional. Other embodiments of the invention provide a power sensor which comprises communication means and data processing means within the housing, as described below.
The at least one remote device 34 receives the processed data from the remote data processing unit 24. The at least one remote device 34 optionally comprises a user interface 38. Whilst a user interface may be provided at the power sensor, it is preferable that it is included at each of the at least one remote device. The remote device 34 is preferably disposed at or near the appliances connected to the circuit containing the power sensor such that the user interface 38 is accessible to the user at or near the source of the power consumption The user interface 38 displays the processed data provided by the data processing unit 24 to enable the consumer to interpret how much power is being drawn through the circuit in which the circuit breaking device is disposed. The user interface 38 optionally also includes means for controlling 40 the switching relay to connect or disconnect the circuit. If a consumer, having interpreted how much power is being drawn through the circuit, wishes to disconnect the circuit to cease the power consumption, he may use the user interface 38 to send a signal, via the remote data processing unit 24, to the switching relay, to disconnect the current.
Figure 6 illustrates a second embodiment of a system according to the present invention.
The power sensor 10 is in accordance with that illustrated in Figures 1 to 3 and ftirther comprises communication means 42. The communication means 42 is provided inside the housing of the power sensor 10 in communication with the measuring means 46.
The power sensor 10 comprises an internal memory 44 for storing data received from the measuring means 46. The power sensor 10 further comprises a processor 48 and is configured to process the data received from the measuring means 46 for communicating to at least one remote device 50 accessible by a consumer.
In the second embodiment, shown in the Figure 6, the power sensor 10 and the remote device 50 are electrically connected to a power line 52. The communication means 42 communicate the processed data to the at least one remote device 50 directly through the power line 52 using techniques well known in the art. The remote device 50 may he a local or networked computer or a bespoke display panel accessible by the consumer.
Of course, communication directly through the power line is merely optional and other signalling means, including using wireless or infra-red signalling or communication via a computer network, are also possible, as described above.
The at least one remote device 50 operates as described above and receives the processed data from the power sensor 10. The at least one remote device 50 comprises a user interface 54 and displays the processed data provided by power sensor 10 to enable the consumer to interpret how much power is being drawn through the circuit in which the circuit breaking device is disposed. As described above, the user interface 50 also optionally includes means for controlling 56 the switching relay to connect or disconnect the circuit to cease power consumption. However, whereas the system illustrated in Figure 5 passed a signal to the switching relay via a remote processing unit, the means for controlling 56 in the user interface 50 of Figure 6 is configured to send a signal directly to the switching relay of the power sensor 10.
It will be understood that this invention has been described above by way of example only, and that modifications of detail can be made within the scope of the invention.
