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 Read More

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 Read More

Last Friday we exported two sets GDZC-10A Portable Transformer Winding Resistance Tester to our regular customer.It's used to measure dc resistance of transformer or other inductive loads. The max test current is 10A.Compared with ordinary transformer winding resistance tester, this equipment equip Read More
