in a induction motor if we put capacitor across it will the
power factor of the motor will improve? if yes how
Answer Posted / gunasekaran
It compensate lagging power factor. motor is inductive load
inductance alway oppose changing current so it is always
lagging with voltage but capacitor always oppose the
changing volage so it always leading PF so this compensate
the lagging reactive power.so active power consuming from
source will be reduced for given load.

why surge protectetor work explain with the help of circut diagram?
In a carnot engine with an efficiency of 40%, the heat rejected to the sink at 27 C is 60 kJ, then the heat supplied in kJ to the engine by the sources is
typically in power distribution substation. 1- Any idea how would be the graph of capacitor bank consumption verses time through the day . 2- How is the switching ( on and off ) of the capacitor bank, per need?
We have a couple of oil tanks at our plant. One of them does not have a lightning arrester installed. My question is it necessary to install an arrestor on every tank or will this particular one be covered by the arrestor installed on the ajdacent tank, Since all the tanks are close to each other. Basically, I want to know that if these arrestors or protection works in a parituclar area of effect or influence. Thanks
