Which are the key selection factors affecting decision to buy a capacitance and tan delta tester? Accuracy: The tester should have a high level of accuracy and the results should be dependable. Range of measurement: The minimum and maximum values of

Measuring the contact resistance of EHV (Extra High Voltage) circuit breakers is important for several reasons. First, it is a key parameter for evaluating the performance of the circuit breaker. Excessive contact resistance increases the likelihood

What is the Tan delta test acceptable value? The tan delta test acceptable value or acceptable value of Tan delta (δ) of both bushings and windings is 0.5 % (i.e. 0.005) at 20°C. Tan delta value in no case should exceed the acceptable value. It is st
