Through the transformer volt-ampere characteristics, 5% and 10% error curve, Angle difference, ratio difference, CT secondary loop system detection, ratio and polarity discrimination, a fully automatic transformer characteristics comprehensive analysis tester is designed. Just set the highest test different voltage and current, the device will automatically boost the voltage, we can automatically describe the volt-ampere characteristics of the research curve, eliminating artificial voltage regulation, artificial intelligence recording and curve drawing and other complex labor.
Transformer characteristic comprehensive tester should pay attention to the problem
1. The secondary coil of the ct should not have a grounding point.
Voltage regulator switch and output switch can be effectively connected and disconnected in the direction of the off position.
3. Equipment must be reliably grounded prior to testing.
4. Zero in time after the end of the test, it is strictly prohibited to stay in the state of high voltage and high current for a long time.
Maintenance of Common Faults
1 No LCD is displayed after the power control switch is turned on.
Solution: Check whether the power input cable is connected.
2. There is no voltage or current output in THE VOA characteristic test.
Solution method: Check whether the voltage regulating switch can be switched on.
3. Voltage and no current in Voan characteristic test.
Treatment: Check whether the test circuit is connected.
4. No current output in variable ratio test.
Solution: Check whether the test line is connected.
5, start the test regulator switch trip.
Method: Test whether the connection point through the transformer can be disconnected.
