China Contact Resistance Test Manufacturers, Suppliers, Factory
Contact resistance test is testing the resistance to current flow, due to surface conditions and other causes, when contacts are touching one another (in the closed condition of the device). This can occur between contacts of: Breakers/Contactors/Relays/Switches/Connectors/Other switching devices.
Contact resistance test also known as Loop Resistance Test or Ductor testing, measures the resistance of electrical connections – terminations, joints, connectors, busbar sections or cable connections and so on. These can be connections between any two conductors, for example, cable connections or busbar sections. The instrument which is used to perform the contact resistance test is called an Ohmmeter, and since its function is to perform the Contact resistance test, the ohmmeter is also known as a Micro-ohmmeter.
When a high current passes through a pair of mechanically independent metallic contacts, the resistance must be as low as possible. An increase in resistance can lead to additional degradation, as I2R losses will cause local heating of the contact surfaces. Weshine® invented range of Contact Resistance Test Set for circuit breaker test measure both steady state and dynamic low resistance values. With test currents up to 600 A available, logging and trending are also available on some models. Weshine® ensure that Contact Resistance Test Set for circuit breaker test are portable, making them suitable for field measurements. Weshine® Contact Resistance Test Sets’ portability makes them ideal for a vast range of resistance testing across the entire LV, MV HV and EHV spectrum.
