“ Earth Leakage Circuit Breaker”. It is used to provide
protection of household circuit from leakage of current
through circuit to earth. Especially, it protects person who
is supposed to get shock while touching the faulty
appliances. Basically it measures difference in current
between “Live wire” & “Neutral wire”. If difference is 0,
fine. Else ELCB gets tripped. You must have noticed that,
difference won’t be zero iff current would have flown
through any person and felt shocked while touched the faulty
circuit. So, tripping of ELCB protects the person from
electric shock

If there is major % of Voltage harmonics in the system, how can it be control or reduced?
why sometime we get electrical shock while touching the ballon of dish tv connection ? which we should not get.
armature winding of dc machine produce alternating emf then it convert in to dc by using commutator.But only we consider armature resistance why don't we consider inductive reactane effect?
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.????
