Abstract

The method involves measuring an electrical signal for the device before and after the earther is connected to an electrical test energy, using the pulse reflection principle. The two results are compared to determine the state of the earth connection The method involves retaining an electrical signal assigned to the device and separated from the earthed energy source according to the pulse reflection principle, and measuring it as a first measurement result. The earther is connected to an energy source assigned to one phase, to load the earth connection with an electrical test energy. After the loading, the earther is separated from the energy source and at least one new electric signal is measured according to the pulse reflection principle, as a second measurement result. The two measurement results are compared, to determine the condition of the earth connection.
