Talking about the main purpose of loop resistance tester

The loop resistance tester has accurate measurement and stable performance and is suitable for the requirements of on-site high-voltage switch maintenance of power and power supply departments and loop resistance testing of high-voltage switchgears. The test current adopts the 100A DC recommended by the national standard GB763, and the loop resistance or contact resistance can be directly measured under the condition of 100A, 200A, 300A, 400A, 500A or 600A current, and can be directly displayed, and can also be stored on the instrument. The number is 100 sets. The saved data can be communicated with the upper computer through RS232 interface, and the data can be uploaded to the computer for saving or printing. It is a special instrument for contact resistance and loop resistance measurement of switch control equipment.

Loop resistance tester type use

Loop resistance tester: Grounding resistance meter uses and scope of application: Grounding resistance is used to directly measure the grounding resistance value of various grounding devices, also can be used for general low resistance measurement, four-terminal (0~1~10~100Ω specifications) The soil resistivity can be measured. Loop resistance tester: single-clamp loop resistance tester

Single-clamp circuit grounding resistance tester performance and characteristics: Unique single-clamp design, to avoid the mutual interference between the two-plier two probes without having to hit the auxiliary pile, direct clamping can be measured.

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 pressure test, and current rms test.

Loop Resistance Tester: Ground Impedance Tester

When measuring with the clamp-type grounding resistance meter series, it is not necessary to use the auxiliary grounding bar and do not interrupt the grounding of the device under test. As long as the grounding wire or bar is clamped, the resistance to ground is measured to 0.1 Ω. Can also be used for current measurement.

Loop Resistance Tester: Loop Resistance Tester

Microprocessor control with high accuracy and high reliability. Three indicators check the wiring status is correct. Read short circuit protection current and ground fault current. The test resistor automatically locks when it overheats.

Loop Resistance Tester: Double-jaw Ground Resistance Tester

With a variety of grounding resistance measurement methods: no auxiliary / three-pole / quadrupole / and pole method ---- for a variety of measurement environments, wide measurement range: 0.002Ω-300KΩ---- meet a variety of requirements.

Loop Resistance Tester: Ground Resistance Tester

Loop Resistance Tester: Digital Ground Resistance Tester
