Transformer winding resistance test in the field Testing Commissioning
Read moreTransformer winding resistance tester helps identify potential issues like winding faults, poor connections, and other resistive losses that could lead to overheating or performance degradation. When you’re using a winding resistance tester, you’re typically looking to measure the DC resistance of the transformer windings at various taps or stages. This can help you detect issues like: 1. Winding […]

what’s the oil bdv tester is uesd for? and how to use?
Read morewhat’s the oil bdv tester is uesd for? An oil BDV (Breakdown Voltage) tester is used to measure the dielectric strength of insulating oils, typically in transformers and other electrical equipment. It determines how well the oil can withstand electrical stress without breaking down. A higher breakdown voltage indicates better insulating properties, which is crucial […]
