Voltage Transformer Error Tester

RS025-Y voltage transformer error tester is equipped with standard voltage transformer with the same transformation ratio as tested voltage transformer, and its precision degree is 0.02 class, which can accurately measure transformation ratio and no-load error of the testing voltage transformer. Then combine with impedance and admittance testing results to calculate voltage transformer error. It has wide measurement range, which is able to expand to 6kV/100V-220kV/100V.

1. RS025-Y voltage transformer error tester is integrated with functions of measuring voltage transformer error by method of error characteristics simulation and measuring voltage transformer error by method of potential difference, facilitating metering devices to conduct field verification on site.

2. There is no need to use a standard voltage transformer, voltage booster, load box and voltage regulating control box to verify voltage transformer on site, and extremely simple test wiring and operation are used to verify electromagnetic voltage transformer, which greatly reduces working intensity and improves working efficiency, and facilitate to develop field verification of transformer.
