Hi I want to know if i can get the tan delta using a power suply of 440V, a power analyzer and using the formula tan delta= IR/IC. Thanks for your answer

The answer is "it depends." The power analyzer needs to be able to measure VERY small currents and their phase angles very accurately, because apparatus insulation is a generally a good capacitor. Leakage currents will be in the range of microamps, with milliwatts of power dissipation. Specialized tan delta test instruments are designed to measure these tiny values, and separate the leakage paths including leakages within the instrument itself.

Ok ok, that´s right the range of my power analyzer is 1mA... But with a oscillospe is possible right? Thanks for your answer
