According to the requirements of the preventive test procedure for power equipment "DL/T 596 — 1996", the test current for the conductive loop resistance test of various switchgear shall not be less than 100A. Due to reasons such as oxidation of contact surfaces and poor contact tightening, the contact resistance increases. When a large current flows through, the temperature at the contact point rises, which accelerates the oxidation of the contact surface, further increasing the contact resistance. If this continues, serious accidents will occur. Therefore, it is necessary to measure the contact resistance frequently or regularly.

Loop Resistance Tester, also known as Contact Resistance Tester, English name: Loop Resistance Tester. Detailed introduction: According to the requirements of the new "Power Equipment Handover and Preventive Test Procedure", the test current for measuring the conductive loop resistance of various switchgear shall not be less than 100A.

Loop Resistance Tester: Ground Resistance Meter uses and scope of application: The ground resistance meter is suitable for directly measuring the ground resistance value of various grounding devices, and can also be used for general low resistance measurement. The four-terminal type (0～1～10～100Ω specification) can also measure soil resistivity. Loop Resistance Tester: Single-clamp Loop Resistance Tester

Single-clamp Loop Ground Resistance Tester performance and features: Unique single-clamp design avoids the error caused by mutual interference between the two probes of the double-clamp type. No auxiliary ground rod is needed; just clamp it directly to measure.

Loop Resistance Tester: Universal Ground/Insulation Resistance Tester

There are many test methods: double-clamp ground resistance test, four-pole ground resistance test, soil resistivity test, insulation resistance test, AC/DC resistance tester voltage test, and current RMS test.

Loop Resistance Tester: Ground Impedance Tester

When measuring with the clamp-type ground resistance meter series, there is no need to use auxiliary ground rods, nor is it necessary to interrupt the grounding of the equipment under test. Just clamp the ground wire or rod to measure the ground resistance down to 0.1Ω. It can also perform current measurement.

Loop Resistance Tester: Loop Resistance Tester

Microprocessor controlled, with high precision and high reliability. Three indicator lights check whether the wiring status is correct. Directly read short-circuit protection current and ground fault current. Automatically locks when the test resistor overheats.

Loop Resistance Tester: Digital Ground Resistance Tester

This tester is specially used to measure the ground resistance value of various electrical equipment, lightning rods, and other grounding devices.
