Answer Posted / srihari
The load is not given so let us assume the load is resistive load.
therefore power factor is unity and at maximum efficiency copper losses = iron losses = 1kw.
100*10^3*1
efficiency= ------------------- = 98.03%
100*10^3*1+1000+1000

In EDO ACBs what is a purpose of closing coil and motor, what is the operation of these devices are they inetconnected. means if we give supply to motor and by BCS we charge Closing coil,what exact is operation is and how it charge a spring of ACB. Sir if anybody has an wiring diagram please send me the link to operate and EDO breaker.
