The circuit resistance tester is mainly used to measure the contact resistance between conductive components in electrical equipment, especially the contact points in high current circuits. It is particularly suitable for measuring contact resistance in key parts such as power systems, high-voltage switchgear, and transformer "joints".

1. Test object

Switch contacts: measure the contact resistance of equipment such as circuit breakers, isolating switches, and load switches.

Busbar connection point: Measure the resistance of the connection point between busbars in substations and distribution cabinets.

Cable joint: Measure the contact resistance between cable terminals and intermediate joints.

*****Transformer connector *****: Measure the contact resistance between the high and low voltage side leads of the transformer and the external connection point.
