what could be the possible reasons for copper cable to have low insualation?
An impedance of 100 ohms resistance and an unknown inductance is connected across the capacitor. The resulting impedance is a pure resistance of 500 ohms ifω = 10^5 rad/sec. calculate the values of inductor and capacitor.
I want to know that a 160kva diesel generator contains capacity of 160kva on each phase like R=160 Y=160 B=160 total RYB=480kva or it is total capacity of all there phases like RYB=160kva ... thanks in advance ...
2 Answers jlpl, JP Saraswat Engineers,
we have one pumping station and 4.6 MW 7 no.s synchronous motors.so there is no required HT capacitor to improve power factor.But we have two no.s of 25 Mva power transformer connect to distribute the power for motors connect with 220 kv line.So i have required the HT capacitor to improve power factor at HT side i mean power transformer bus side.So please suggest how much HT capacitor banks required for same.
