For the past six months there has been increase in my electricity bill. The reason is that the maximum demand is higher (6 kW) than the sanctioned maximum demand (3 kW.)
We have a 3HP 3 phase borewell motor. We have had the same motor for more than five years now and for the past six months it seems to be drawing 6.2 kW power instead of under 3 kW. This borewell motor is also the only load connected to the energy meter.
Nothing has changed in the past six months except some rewiring at the energy meter (this is what I am suspecting).
The people at the electricity board are asking me to increase the sanctioned limit.
The current drawn is ~10 amperes and RYB to neutral voltage is ~230 V.
How can I troubleshoot this issue? Nobody here seems to understand that the issue is the motor drawing 6 kW while it should be drawing less than 3 kW.
Could bad wiring at energy meter cause this, or a faulty energy meter? Could the motor itself be faulty? It seems to be doing its job of pumping the water perfectly, though.
In the second picture, I see there's an additional red wire going into the fuse with Blue phase. I'm not sure where it is coming from.
