JYL 100A handheld high voltage switchgear Contact Resistance Tester Circuit Breaker Contact Resistance Tester

Product Description

The instrument is suitable for testing high voltage switch, circuit breaker contact resistance with high output voltage and long duration can be continued for a long time. The primary resistance of the current transformer can be measured, and the grounding wire is measured in groups.


Function Introduction

1. With built-in lithium battery(12V/5.2AH,Charging time is about 3 hours using special charger JS-042203(DC4.2V/2A*3 sets)), not need AC power supply. The instrument is suitable for field use.

2. The output current is above 100A.

3. The shell has the function of insulation, sealing, anticreep, anti-wind, and anti-sand.

4. The soft rubber at the corners protects the instrument effectively.

5. Anti-power frequency interference. The instrument can be used in 1000kV substations.

6. With 5.6 inch color touch screen. The instrument can be used indoor and outdoor.

7. With mechanical key for "run/stop".

8. With the function of monitoring and protecting the Battery power and the temperature of the instrument.

9. 100A tapered connector is used for current extraction.

10.With " flash disk" interface for exporting data.

11.With data storage function,it can store 100 sets of data.

12.With function of automatic shutdown: shutdown without operation exceeding 5 minutes.
