Why three-phase transformer should be tested with special tr

The three-phase transformer ratio tester, also known as zc-203c special ratio tester, is the third generation of professional ratio testing equipment newly launched by Wuhan Zhizhuo measurement and Control Co., Ltd., which is especially suitable for Z-winding transformer, rectifier transformer and balance transformer testing. 

The instrument adopts large screen liquid crystal display, Chinese menu and Chinese character printout, with friendly human-computer interface, perfect function and convenient operation. It is a theoretical instrument for transformer ratio, group, polarity and angle test of power system, transformer manufacturer and railway electrical system. 

Three phase transformer is tested by special transformer ratio tester with the following purposes:

1. Check whether the transformation ratio is consistent with the nameplate value to ensure that the required voltage transformation is achieved.

2. Check whether the indication position of voltage tap changer is correct.

3. Check the turn ratio of each coil to determine whether there is turn to turn short circuit in the transformer.

4. Measure the unbalance degree of the transformation ratio of the three-phase transformer itself.

5. Provide the accuracy of transformer ratio to judge whether the transformer can operate in parallel.
