The wiring of different products of the power test equipment is different when doing different tests. Today, let's follow the explanation of our technical engineer to take a look at the wiring method of the comprehensive tester for transformer volt-ampere characteristics.
The CT ratio polarity test wiring of the transformer volt-ampere characteristics comprehensive tester is shown in the figure.
Note 1: In the transformer volt-ampere characteristic comprehensive tester, due to the large current on the primary side, please try to use a thicker and shorter connecting wire to prevent the current from being unable to rise to the "one-time measurement current" due to excessive primary wire resistance value.
Note 2: When the transformer volt-ampere characteristic comprehensive tester is doing the transformation ratio polarity test, please disconnect the grounding wire of the CT secondary winding first to avoid damage to the device.
