Power Factor Correction Units, or Capacitor banks as they are commonly referred to, are systems that help in improving the Power factor of a network. In simple terms, power factor is a measure of how effectively a load uses the power delivered to it from source, such as an electrical utility.

Power Factor of a network is the ratio of active power (kW) to apparent power (kVA) and can be leading or lagging with values ranging from 0 to 1, with a higher value representing better power factor. The power factor of a network is calculated as cos Φ, where Φ is the phase angle by which current lags the voltage in the system.

The purpose of power factor correction is to bring the power factor closer to 1, by supplying or absorbing reactive power, which is usually achieved by adding capacitor banks

EML undertakes assessments through energy audits to ascertain the requirements for power factor correction units for our customers and thereafter supply and commission at their facilities.
