ZX-Q15 Cable High Resistance Fault Location Bridge Tester

ZX-Q15 cable high-resistance fault locating bridge adopts a switching power supply to form a high-voltage constant current source, uses a high-sensitivity amplifier and a galvanometer to indicate balance, and forms a balanced bridge with a proportional potentiometer, and the whole is placed at a high potential. The test line is a specially designed double-core high-voltage rubber cable. The four-terminal resistance measurement method is used to avoid the error introduced by the lead resistance. The operation button on the panel is at ground potential, and the bridge is operated through the insulating rod. The high-voltage constant current source and electric bridge are integrated in a portable industrial plastic chassis. Therefore, the device has high voltage, light weight, convenient operation and safe use.
