Applications and Industries where it is used

Electrical Panel

  • Where: Power Factor (PF) meters are used in capacitor panels, LT panels, and distribution panels to monitor reactive power
  • Why: To monitor and correct power factor, enhance energy efficiency, and reduce electricity costs and penalties.

Building Management Systems(BMS)

  • Where: Power Factor (PF) meters are used in BMS panels to monitor the power factor of building electrical loads.

  • Why: To improve energy efficiency, avoid utility penalties, and ensure optimal load management.

Generator / DG Set Panels

  • Where: PF meters are used on the output side of Generator / DG Set panels.

  • Why: To ensure efficient generator performance, prevent overloading, and maintain voltage stability.

Commercial Sub Metering / Retail Malls

  • Where: PF meters are used in tenant distribution panels and main sub-metering panels of retail malls

  • Why: To optimize energy usage, avoid power factor penalties from utilities, and ensure balanced load management across tenants or zones.
