What power factor should each type of equipment in my factory run at?
BEE's MSME guidelines list target power factors of 0.95 for induction motors after correction and for induction furnaces, 0.99 for the distribution system, 0.90 or above for welding machines and DC drives, and 0.95 or above for fluorescent lamps. Automatic power factor controllers and capacitor banks get you there.
Targets by load
- Induction motor, measured after the correction system: 0.95
- Distribution system: 0.99
- Induction furnace: 0.95 (capacitors usually come with the furnace)
- Welding machine: 0.90 and above
- DC drives: 0.90 and above
- Fluorescent lamp: 0.95 and above
How to reach them
Install an automatic power factor controller with capacitor banks at the receiving end, and check the induction furnace's own capacitors. Measure power factor daily on furnaces and other large loads.

- Direct online starters for motors up to 5 hp
- Star-delta starters from 5 to 20 hp
- Soft starters above 20 hp
Why it shows on the bill
On a kVAh bill, a low power factor raises the units you pay for. On a kWh bill, many tariffs add a penalty or give a rebate around a set power factor. Your state tariff order sets the numbers.
What Senseible does here
Senseible reads the power factor printed on kVAh bills and flags a low one as a saving to look at, with the estimate labelled as an estimate.
