Answer / dinesh
since %impedance is the per unit value, u can get the short circuit fault current level by,
Ifault = Irated (phase current) / %z..
Similar method if u need fault level MVA....

Answer / k.prakashchandra
% impedance( Say P )= I rated x Z x 100 /V rated. Hence Z =
P x Vr /Ir x 100. Fault current If = Vr /Z .Then If= Ir x100/P

Answer / k.prakashchandra
I think you have to multiply by 100 ,in the above answer as
otherwise the fault current will be less than the rated.

when ELCB breaks the circuit than INVERTER auto-connect the circuit to the battery than how can the operetor is safe??
What is ELCB?
I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?
