Power Factor Correction Capacitors

VarPlus & Easy Can are low voltage aluminium can capacitors specially designed to contribute to power quality and power factor mitigation and deliver a long working life in industrial networks, with low losses in standard, heavy-duty and severe operating conditions.

Power factor surcharge is applied when your power factor is below 90%. Power factor refers to the ability of your electrical system to convert electric current into useful work such as heat, light, and mechanical motion. To use electrical power efficiently your system should draw mostly real power, measured in kilowatts (kW), from our system. If your equipment draws too much reactive power, measured in kilovolt-amperes-reactive (kVAR), it can’t perform work as efficiently and limits the capacity of our lines to deliver real power and quality voltage to your facility.

The total power your facility draws, also called apparent power, is the square root of the sum of the squares of real and reactive powers. The ratio of real power to total power is called power factor, and your equipment is performing best when that ratio is between 90% and 100%.

To calculate power factor we use the following formula:

Power factor = Real power consumption / Apparent Power Consumption
