Abstract :
A phase comparator has been developed to compare the phase angle of AC shunts at frequency up to 200 kHz at National Institute of Metrology (NIM) in China. The comparator can supply two currents in which one of the current is two times of the other. With this comparator, the phase angle of two AC shunts can be compared both in nominal current.
