When induction motor is started,we see all other electrial
appliances connected on the same supply are dimmed out for
some moment why?
Answer Posted / kuruvilla chacko
induction motor is a reactive power hogger.since reactive
power is connected with voltage,by absorbing huge amt of
reactive power,it depletes the voltage provided to other
machines such as fans,mixers etc...thus there is dimming.this
can be rectified by using capacitor banks.

Why reactive power is needed in a power system? How is it being absorbed or delivered by alternators? For reactive power control we are changing excitation but reactive power absorbing or delivering related to stator. How these two are interlinked? i want a detailed explanation with necessary expressions and figures?

Practical condition in 400KV Sub station:- Breaker(open) , isolator(open), Earthing (close) at both end e.g A & B. Now Open A Stn Earthing than Open B stn Earthing (Which have a 50MVA reactor) , AND suddenly show R,Y,B phase 704KV,573KV,118KV respectively. Que is without closing of breaker how it is possible.????

In Power Line Communication (PLC) the wave trap is used to block communication signals from entering neighboring lines. My question is this: Why do they allow for different filtering arrangements on these wave traps? Isn't it always going to be a low pass filter since we want the power frequency to go through, and the comm signal blocked?
