If the test voltage of the test sample is high and the capacitance is small, the series resonance test method can generally be used.When W0L=1W0C (C includes CX, C1, C2) in the test circuit, the test circuit produces series resonance, which can generate a high test voltage on the test sample (the te

Recently, one of our clients successfully provided AC withstand voltage testing for 220KV cables to NGCP in the Philippines using the GDXZ Series Resonant AC Hipot Test System purchased from our company. And received high praise from NGCP in the Philippines.The National Grid Corporation of the Phili

The error of current transformers is divided into ratio error and phase angle error:The ratio error is the current value indirectly measured through the secondary circuit (KeI2 minus the percentage of the actual value of the primary current to the actual value of the primary current). That is, the p
