Answer / santosh89

it will depend on load hence the p.f of of the motor.If the load will vary we use automatic type pf controller.
If the pf of motor is not known...there is a jugaad rule of thumb that (kvar<=33.3%of motor HP).In this case capacitor should be less than 11.55 kvar

In my project i am layout cables under the Maintainance bay /Maintainance yard in the TG Building. Whether in this route i can lay the H.T.Cables??? i am taking all H.T cables from the H.T Transformer to the TG Building..

1. for eg, capacitor is used for many purposes(it act as filter, oscillator, bypass capacitor, memory storage etc...) 2. Please tell me some example circuits for different uses of capacitor( whenever and whereever and however we used capacitor as a filter, oscillator tuning etc..) 3. similarly for inductor and resistors(it act as what?) and when and how we want to act as like that?, and how we can used these components depends upon our requirments with example circuits and explanation? design to act as these components depends
