Energy savings, control the power factor helps ?

Wishes to save energy and reduce expenses.

Power factor KVAR correction

Companies that tout power factor improvement (kVAR correction) and

transient voltage suppression are a good example of this bad trend.

Lately we are seeing more and more of thes

Transient voltage surge suppression TVSS

First, transient voltage surge suppression (TVSS) plays a valuable role in improving power quality to protect sensitive equipment inside a facility. However, TVSS does not save energy. TVSS’s are only active a tiny fraction of a second to protect against voltage surges which only last for less than a millisecond. To actually reduce energy consumption the TVSS would need to actually cut power consumption for an extended period of time which is not what they are designed to do.

Again, TVSS is important to protect sensitive electrical equipment

but buyers should avoid vendors promising, or even guaranteeing, that they will reduce energy consumption.

Now what about vendors who claim that improving power factor will save 15% or 20% or 30% of energy consumption and corresponding cost? This one is a little trickier.
