Summary
The Arrester is suitable for testing the internal defects of 10KV and below 10KV MOA (metal Oxide Arrester).Before the annual season of thunderstormsit 's necessary to test metal Oxide using 1mA DC voltage and 0.75U1mA leakage current at Power plants/substations.The equipment was developped according to the requirement of site it 's integrated with DC HV supplymeasurement and control system. it has the characters of small size and light weight.


Feature
1.Supply power: AC220V or Charging battery.
2.LCD display test datas.
3.Convenient to carry.

Application:

TKBLQ-I zinc oxide arrester tester is a special instrument used to test the electrical performance of arresters. The instrument is suitable for live or power failure detection of arresters of various voltage levels, so as to timely detect the internal insulation damp and valve aging and other dangerous defects.
TKBLQ-I zinc oxide arrester test instrument is easy to operate and easy to use. The whole measuring process is controlled by microcomputer. It can measure the total current, resistive current and its harmonics, power frequency reference voltage and its harmonics, active power and phase difference. The real waveform of voltage and current can be displayed on the large screen.


Features:

1. 5.7 "320 Ã?? 240 LCD, high-speed thermal printer; graphic display, intuitive interface, easy to operate and use.

2. It is applicable to live arrester, power failure or laboratory.

3. The current and voltage sensors are completely isolated, safe and reliable. A, B, C three-phase arrester can be stored as a group of test data.

4. The instrument can test continuously, display voltage current curve, and print data and curve quickly.

5. The internal configuration memory can store 200 groups of test data when power down.

6. With RS232 communication interface, the test data can be exported through the upper computer.
