I have 30 kw motor load & i have selected 10 kvar capacitor bank for power factor improvement.my existing p.f is 0.85 & proposed p.f is 0.99 so ,is it right selection?
2 nd question how to connect c.bank whether in delta or star connection & how to decide it?
as per electrical calculations if we want maintained .99 pf we should have 14.31KVAR is sufficient.

Dear Sir, we met a disaster with our 62.5 kva genset, after rewinding we informed by our contract engg that due to return current coming in neutral & impropper earthing this happend. But after all set up & load balance we checked & found again we have about 20 to 32 amp return current on neutral. we have 12 airconditioner + 12 mini fridge on single phase line. Pl suggest any idea to solved this problem
