Resistance Testing Solutions - SMC

Contact Resistance TestingWinding Resistance TestingInsulation Resistance TestingGround Resistance TestingThe contact resistance testing of electrical connections is very important for contacts that carry large amounts of current (e.g. switchgear busbars, circuit breakers, joints, etc) as higher contact resistance leads to higher losses, lower current carrying capacity and dangerous hot spots in the substation, so that resistance testing is used for detecting and preventing future problems. Contact resistance testing is performed using micro-ohmmeters, which use the four-wires voltage drop method for accurate measurement. SMC offers different solutions for this application: 1. PME-500-TR: combining two test sets in one, providing in the same report the timing and synchronization of the circuit breaker poles, and the 3-phase contact resistance measurement. 1.

Switchgear - Wikipedia

In an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type of equipment is directly linked to the reliability of the electricity supply. The earliest central power stations used simple open knife switches, mounted on insulating panels of marble or asbestos. Power levelsGet price
