Abstract
PURPOSE: To directly measure loss angle of earthing line in live condition without stopping machine operation in the line, a filter is used which passes only frequency component required for feed back current in earthing line casued by loss angle measuring voltage.
CONSTITUTION: Transformer 17 and power supply 18 energizes oscillator 1 to produce measuring voltage, which is applied to earthing line EL through transformer 2. Then, frequency components required for feed back current passes through filter 5 and is inputted in multiplier 7 and multiplied by measuring voltage. This produces signal proportional to the active component of output from the filter 5, and the signal is squared 9. Absolute value of the filter 5 output is squared 12, from the value of which the output 9 is substracted, then square root value 14 of which is obtained. This provides signal proportional to the reactive component of the output from the filter 5. The output from the multiplier 7 is devided by the output from the square root circuit, and the output from devider 15 is used to measure loss angle.
