It is the angular setting provided between the reference voltage and operating current beyond which the relay will operate. During the normal operating conditions, the MTA should be adjusted to cos theta= 0. so the angle should be 90 degrees. But once any forward side fault occurs in the system, the angular difference will be less than zero so the operating quantity will be more than restaining quantity.

what is the series parallel connection of capacitors? and how can we use these application in three phase motors for controlling torque?
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
