SRT Loop Resistance Tester

1.Performance

Measuring the contact resistance and loop resistance of high-voltage switches, measuring high-voltage switch cabinets and bus loop resistance tester is a combination of traditional micro-ohmmeter and milliohmmeter.

2.Function

The SRT loop resistance tester is developed in accordance with the national standard GB11022-1999, using the DC step-down method to measure the contact and loop resistance of high-voltage switches. Use a dedicated high-frequency switching power supply to provide the instrument with a DC test current greater than 100A; use a microprocessor to automate the measurement process. When measuring, just turn on the instrument power supply and press the measurement button to change the loop current to the device under test. The loop resistance is automatically measured and displayed on the LED digital tube. Due to the use of advanced high-resolution AD converters and software to process the test data and digital filtering, the instrument has strong anti-interference ability, thus ensuring the measurement accuracy.
