ST Portable Transformer/Dielectric Oil Tester kit is apply for speedy and
accurate testing of dielectric strength of transformer and circuit breaker oil
under test room condition in accordance with IEC international standard.
ST oil dielectric
strength tester can be divided into single cup three cups and multi-cups.
ST tester is simple and easy to operate due to adopt automatic
digital microcomputer control, the measurement precision is high,
anti-interference ability is strong, safe and reliable.
Functions:
1.Breakdown test of user-defined
2. Proof test
3. IEC156/IS6792/BS5874/
4. ASTM D1816 standard test
5. ASTM D877 standard test
6. 5 minutes standard test
7. Manual test
8.Temperature measurement
9. Calibration interface for customers
10. Unloading data to PC and making word report automatically.
11. Result print
Main features:
1. Simple operation, automatically (can be finished just press on key)
2. Menu controlled. Input data is clear
3. Can store 99 groups of oil testing data, which is convenient to reading and
print. The testing data can keep 100 years under the condition of power off.
4. System time can go on running under power off;
( The system time is just for reference which can not be the standard of
timing)
5. Can upgrade software through RS232
6. High capacity of anti-jamming, high precision of testing.
7. Small volume, light, which can be operated in the open air very conveniently
