I hv a question regarding power factor improvement just
after transformer. I request you to reply me plzz. thank
you sir.
My friend has a small unit of fabrication. in his factory
the main load is a welding machine, lathe machine, grinding
machine. this load is not continuous type. now our
electricity board has installed 16 KVA, 11000/433 V
transformer for our factory. In the energy meter (trivector
meter) at LV side of transformer, i hv seen power factor
value of 0.15 only when only 3 KW load was flowing. Further
electricity board has suggested to install 4 KVAR capacitor
at LV side after energy meter. Now my question is that if
we permanantly install and switch on 4 KVAR capacitor after
energy meter, during some load on transformer and also
without any load on transformer, wht will be the power
factor shown in energy meter?i dont want to get any penalty
by electricity board, so plz suggest me if i can
permanantly install and switch on the 4 kvar capacitor or
not at LV side of transformer just after energy meter?
Thank you again and awaiting for ur positive reply soon.

Answer Posted / surya

the 4kvar capacitor improve the pf but you must keep in
mind that installed the capacitor permanentely only at load
time.switched off the capacitor on unload time since i
think at unload time the 4kvar capacitor become a self-load
& increase your electricity bill.

A 400 V, 50 Hz, Δ connected synchronous generator has a field reactance of 0.1 Ω and armature resistance of 0.015 Ω. At full load, the machine supplies 1200 A at 0.8 pf lagging. Under full-load conditions, the friction and windage losses are 40 KW and the core losses are 30 KW. What is the machine’s overall efficiency? Ignore any field circuit losses.

Is a contactor (or master relay) required between incoming lines and a VFD? The question goes to safety. If a contactor were used before the VFD and an e-stop engaged then the motor will coast to a stop (i.e. VFD loses power) instead of stopping much faster if the VFD braking fucntion were used. It would make more sense to keep power on the VFD.
