Product Introduction
Transformer turn ratio test is the necessary testing program in power operation transformer produce, user handover and maintenance, which can effectively monitor the quality of ex-factory transformers and during usage. The testing can prevent transformer's turn short circuit, open circuit, wrongly connection, contacting fault and internal fault of voltage regulator switch.

Product Features:
1. Adopts three-phase precise inverting power source, eliminating resonant wave's effect when test, testing more accuracy. When the working power is alternator, without any effect.
2. Adopts three-phase output voltage, improving the testing speed, also can test the interphase angle, automatically recognize transformer's connection groups 0-11.
3. Applied to many kinds of transformers, like Z-type, rectify-type, grounding-type, electric furnace-type, phase moving-type, balance-type, scott-type, reverse scott-type and other kinds of special transformers.
4. Adopts three-phase precise inverting power source, having the function of high/low voltage reverse connection, turnings short circuit protection, tap changer failure protection, output full short circuit protection, improving the stability of instrument.
5. After inputing rated parameters, the tester can automatically test transformer's turn ratio value, error value, tap changer tap position, especially for the asymmetrical tap changers, it can detect out the tap changer's accurate position, at most for 99 tap positions.
