Title: Detector for leakage current of zinc oxide-type lightning arrester
Inventor: TAWARA KAZUHIRO
IPC: G01R31/02
Filed: 1996-06-13
Abstract: PROBLEM TO BE SOLVED: To obtain a detector by which a leakage current can be detected with high accuracy by a method wherein a capacitance-portion leakage-current signal is generated by a computing operation on the basis of a total-leakage-current signal and a resistance-portion leakage-current signal is detected on the basis of both signals. SOLUTION: A zinc oxide-type lightning arrester 2 is connected to a transmission line 1 to which an AC voltage is applied, and a detector 3 which is connected across the lightning arrester 2 and a ground detects a total-leakage-current signal which corresponds to a total leakage current flowing to the lightning arrester 2. On the basis of the total-leakage-current signal, its fundamental wave component and a phase difference are computed 21, and the peak value of a capacitance-portion leakage-current signal is computed 22 on the basis of the leak value and the phase difference of the fundamental wave component so as to be output. In addition, a phase shifter 24 adjusts the fundamental wave component on the basis of a reference phase which is detected 23, and it outputs a phase-shifting fundamental wave component.  A gain control circuit 25 generates a capacitance-portion leakage-current signal while the leak value of the input phase-shifting fundamental wave component is made to agree with the peak value of the input capacitance-portion leakage-current signal. Then, a differential amplifier 26 detects a resistance-portion leakage-current signal on the basis of the difference between the total-leakage-current signal and the capacitance-portion leakage- current signal.
