what is power factor?
is it good or bad for a system?
what will happen if power factor increase or decrease?
Answer Posted / saran
The power factor is the ratio active energy and apparent
enery is called power factor.
the power factor is incresed custormer used more power
energy leading current so fanaty give TNEB.
the power factor is decress custormer used less power i.e
legging power factor between -0.9 to -0.99, that is
maintance lagging power factor one is unity power factor.
more all use inductive load must use power factor,
power factor leg and lead applied by voltage pai angle.
