Is Power Factor Correction Justified in the Home?

Power factor corrections are highly significant since you might be paying for reactive power that is actually helping you in no way. Yes, you read that right. Reactive power is a wastage and is not used in any real work, but you will be charged for it nonetheless. Fixing the power factor ensures less current being drained, which means reduced electricity bills, less heat generation, and greater longevity of the electrical system.

Many discoms bill the baseload (kW) and a maximum demand tariff. Suppose this maximum demand tariff is calculated in kVA. In that case, correcting the power factor reduces the system’s kVA, thus lowering the maximum demand tariff, which reduces your power-related expenditure.

Power factor (PF) is evaluated between 0 and 1.0, typically given as a percentage. If your facility’s PF falls under an established level (usually 95-96 per cent), your provider will charge a reactive power fee. This is because low PF implies an inefficient load source that generates reactive (i.e. non-working) power that the utility has to make up for.

Power Factor = True Power/Apparent Power

  • Real Power - Power used to run equipment, shown in kW.

  • Reactive Power - Power that does not end in any use - loss.

  • Apparent Power - Real Power - Reactive Power

The fact is that your PF percentage denotes to you how much of the total current is being consumed by you, which is indeed used for operating devices and running appliances. For example, a PF of 80 per cent means that 20 per cent of the current flowing into your system is non-working power and is nothing but a loss for you.

Benefits of Power Factor Corrections

PFC helps in avoiding unnecessary power penalties. Industries and residences can benefit a lot from PFC. It also leads to reduced demand charges. It also boosts the load-carrying capabilities of the circuits. PFC also helps in improving the voltage level and diminishes power system losses. 

Schneider Electric India offers the latest solution for power factor correction. The brand has power factor correction capacitors and components like VarplusCan and EasyCan, the new generation LV power factor capacitor that provides high reliability, enhanced longevity, and improved current capacity. They also have a Varlogic Power factor controller that effectively manages the system's reactive power and oversees the connection and disconnection of capacitors to ensure targeted power factor. 

With Schneider India, you can also avail of the automatic power factor correction panel, which is excellent for maintaining the desired power factor even under fluctuating load conditions. It can be used in steel rolling mills, chemical industry, cement plants, sugar plants, textile mills, hospitals and hotels, automobile industry and construction sector
