Loop Resistance Tester, Also Known as Contact Resistance Tester or Micro-ohmmeter
The Loop Resistance Tester (also known as Contact Resistance Tester or Micro-ohmmeter) is a specialized instrument used in power systems to accurately measure the conductive loop resistance of high-voltage electrical equipment such as switches, circuit breakers, and disconnecting switches. It evaluates the connection quality of equipment conductive loops by detecting resistance values at the micro-ohm (μΩ) level, serving as a key testing tool for ensuring the safe operation of power equipment.
