Please give me a solid reason there are 2 ELCB's If we take
Phase from ELCB NO:1 an Netural from ELCB N:2 why ELCB is
tripping when we connect the Load?please brief me with detail

It is RCCB and not ELCB . You are creating imbalance by
removing one wire

Answer / rajesh verma
Dear
if we take phase from one RCCB and Netural fromsecongd then
it will get tripped because of phase unblance. ELCB will
not get tripped while taking phase & netural from different
source ELCB

Answer / jessie
1st: check the ELCB Current capacity maybe overloaded if you connect your additional load. used ohm's Law formula I= P/E
2nd. check the continuity of Earthing Connection to your additional load.

I have a 25kVA three phase transformer on our property. Will this transformer be large enough to run a large home with swimming pool, spa, 2 off full size reverse cycle air conditioners to service a 100 square house (10,000 square feet or 930 square metres)and the general power consumption of this house without upgrading to a 63kVA transformer.

A 100 kVA , 400 v/250 kv testing transformer has 8% leakage reactance and resistance on 100 KVA base . A cable has to be tested at 500 kv using the above transformer as a resonant transformer at 50 hz . if the charging current of the cable at 500 kv is 0.4 A find the series inductance required . Assume 2% resistance for the inductor to be used and the connecting leads . Neglect dielectric loss of hte cable . what will be the input voltage to the transformer ?
I have a drawing of a wound rotor induction motor for a crane. This crane motor has 5 forward speeds & 5 reverse speed implemented of course with different amount of resistance for each speed setting selected. What has got me scratching around is the fact that 8 of the 10 speed selections switch in uneven (unbalanced) amounts of resistances on each of the 3 connections to the motor's rotor.Can this be possible? I would have assumed this would produce unbalanced rotor currents and therefore vibration in the motor. I would greatly appreciate anyone's comments on this. Many thanks, Confused.
