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.
Motwane’s patented Dual Ground Technology allows you to test your devices with grounding breakers from both sides to work under the presence of noise and higher interference in a live switchyard of up to 765KV
Offers higher accuracy and accurate resistance measurement
