Product Description

HV Hipot GDHL-200B Contact Resistance Tester (Microhm Meter) FOR High Voltage Switch

Description

The performance of the conductive circuit of the circuit breaker is important to ensure the safe operation of the switch. The pros and cons of the conductive performance can be reflected by the size of the resistance of the conductive loop. Therefore, the IEC standard and the manufacturer have stipulated that the loop resistance should be measured, and there are clear specifications for the loop resistance of various types of switches. The loop resistance tester is a testing instrument meets the requirements of GB50150-2006 and DL / T 845.4-2004 regulations. It is widely applicable to the measurement of contact resistance, loop resistance, cable, wire, and weld contact resistance of various electrical switches.

Application
 

•  High,middle and low voltage circuit breakers
•  High,middle and low voltage disconnecting switches
•  High-current bus bar joints
•  Cable & Welding joints

 It is suitable for high current, micro ohm measurement.

Features
 

1. Output high-current continuously.
2. Quick and accurate test. Test current is generated from high-precision 50A/100A switching mode constant current power supply, no need for manual adjustment.
3. Adopts four-terminal wiring method. The influence of test line resistance on test results is effectively eliminated.
4. Stable performance. There is over-heat protection crcuit designed for long-time working.
5. Light weight, easy to carry and operate.
