Product Information

We selected the field of energy conservation or energy saving, witch is a need of the time and is receiving attention from the governments and from private sectors as well. Out of various various electrical fields this area is one part , is a subject of our expertise and experience.

Power factor is the ratio between true power and apparent power,
Thus, P.F. = KWH / KVAH
Here, KWH is an abbreviation for Kilo Watt Hour or Unit.
KVAH is an abbreviation of Kilo Volt Ampere Hour.

This ratio is normally a fraction figure but ideally should be 1.0 (Unity) or as close to unity as possible. This ratio is called power factor. Any value of power factor near to unity is called good P.F. and similarly below 0.92 is assumed as poor power factor.

Power Factor - The power factor of any power consuming centre depends upon three types of loads being used in present day industries. To explain, normally there are three kinds of loads present in any industry, individually or in combination.

Resistive load: Under this condition the P.F. is always 1.0, i.e. unity. This is an ideal situation. This is achieved with loads like resistive heaters, filament lamps etc.
