ZD1C Contact Resistance Tester
As distribution networks carry heavier loads, regular checks of contact resistance help detect faults early and prevent overheating. This contact resistance tester measures contact resistances of circuit breakers, disconnecting switches, earthing switches, bus joints, bushing contact joints, and welding joints, as well as other low-resistance applications. It supplies 100 A DC current for resistance testing, measures the voltage of the ···
As distribution networks carry heavier loads, regular checks of contact resistance help detect faults early and prevent overheating. This contact resistance tester measures contact resistances of circuit breakers, disconnecting switches, earthing switches, bus joints, bushing contact joints, and welding joints, as well as other low-resistance applications. It supplies 100 A DC current for resistance testing, measures the voltage of the test object, and calculates resistance using Ohm’s law (R =
