| Abstract: | In order to further improve the measurement accuracy of planar Rogowski coil current transformer based on PCB(Printed Circuit Board),the PCB coil equivalent circuit is set up and the rela-tionship between its induced secondary voltage and measured primary current is derived.Its error characteristics are analyzed in the aspects of power frequency and temperature.It is pointed out that,theresistance of sampling resistor(input resistor of integrator) is an important factor affecting the frequency and temperatu... |
