Answer Posted / rsundareee
your original p.f is 0.8(Tan 0.8) and you required p.f is
0.95(Tan 0.95).Required p.f = kW(Tan0.8 - Tan 0.95),when
you select the breaker rating of Capacitor bank you have to
conside the Hormonics (33%),For exambe breaker rating will
be 100A it shall be (100+33=133) 160A MCCB.
