Capacitance and Tan Delta Test / Measurement of Capacitance and Dissipation Factor

What is the value of Tan Delta for good insulator?

Good....also send me ppt file. Thanks frnd!!!

The value of Tan Delta for healthy insulator should be as low as 0.1.

Hi, I am sorry but I don't understand something. Since tand=wCR how come that the tand is independent of frequncy? I am a bit confused there

Also at the last slide you use tand=1/wRC but before you have used tand=wRC as the value of tand? Why is that?

Dear Leo Silver, if you equate an real Capacitor to a Parallel plate Capacitor (ideal Capacitor) in series with Resistance then Tan d will be equal to RwC and if parallel equivalent circuit then 1/RwC where where R is resistive current path representing the dissipation through the ideal Capacitor C. w is the angular velocity depends on the frequency of the voltage applied to C

Air Capacitor is not loss free

at balance condition Z1.Z4= Z2.Z3

please tell in Hindi

Just love the way of your explanation! Each point you clear so minutely! ❤

Sir can explain the test procedure for CVT


And one mor doubt ,so we need to do every CT without c point to DO IN GST G MODE
