what is the difference between ACTIVE POWER and REACTIVE
POWER.I WANT CLEAR ANSEWER.
Answer Posted / suseendran
The power required to run a pump using a motor is active or
real power(KW).
The inductive nature of the motor windings will impose a
power whose current flow direction will be, for one half
cycle it flows from supply to motor and in the next half
cycle it flows from motor to the supply. Hence it is called
circulating current. It just flow TO and FRO between the
supply point and the motor. The power of this circulating
current is called as reactive power(KVAR).
Also this is the reason why electricity board charge us for
KW power and not for KVAR power.

Explain Active power,reactive power,how its related to each other , & inductive ,capacitive.
Calculate torque developed by the 3-phase, 5 H.P., 4 pole induction motor runs at 1500 rpm A 23 N-m B 21 N-m C 10 N-m D 0 N-m
At the starting of dc motor and syn.motor and induction motor high current flowing through the winding. Due to this the windings burnt out. To avoid this different types of starters are used. But incase of transformer what Will be used (At starting no emf is induced in the primary winding)?

Why it need to form a capcitor when it not been in use from three or two year. Plz describe it technically.
what is the advantages og idmt relay over magnetic relay??
how does the terminal voltage of transmission lines increase when a capacitor is connected???? This happens not only in transmission lines but also in all circuits. How??? When a capacitor is connected in a transmission line, capacitor also takes energy from the same supply. But how is it able to increase the terminal voltage??? Practically What sequence of events happen during increase in voltage???
