Product Description

Products introduction

KDHL-200A loop resistance tester is designed according to the power implementation standard DL/T845.4-2004 of the People's Republic of China, using a combination of high-frequency switching power supply technology and digital circuit technology.

 

It is suitable for measuring the loop resistance of switch control equipment. Its test current adopts the DC 100A and 200A recommended by the national standard. The loop resistance can be directly measured under the condition of 100A current, and the loop resistance can also be directly measured under the condition of 200A current.

 

The final test results are displayed digitally. The instrument has accurate measurement and stable performance, and meets the requirements of on-site high-voltage switch maintenance of power and power supply departments and loop resistance testing of high-voltage switch factories.

Performance characteristics

1. Large current: The new power supply technology can continuously output large current for a long time, overcoming the disadvantages of instantaneous current of pulse power supply, and can effectively break through the oxide film of switch contacts to obtain good test results.

2. Strong anti-interference ability: Under severe interference conditions, the last bit of data on the LCD screen can be stabilized within the range of ±1 word, with stable reading and good repeatability.

3. Long service life: All high-precision resistors are used to effectively eliminate the influence of ambient temperature on the measurement results.

4. Easy to carry: small size and light weight.
