Contact Resistance Meter
-
The Motwane Manufacturing Company
High contact resistance values are a definite cause of the failure or less than optimal performance in a wide variety of electrical devices. Contact resistance testing is therefore most critical to measure the resistance of electrical connections in switching devices, circuit breakers, isolators, busbars, relays, joints, connectors, cables, and cable joints. The device helps to find destructive or corroded contacts and hence protects substation devices from damage.
