Applications and Industries where it is used

Electrical Panel

  • Where: AC single source energy meters are used in main LT panels and individual distribution panels to measure total energy consumption from a single incoming power supply.
  • Why: To track energy usage accurately for load monitoring, billing, and energy efficiency management.

Building Management Systems (BMS)

  • Where: AC single source energy meters are used in BMS panels to measure energy consumption of building utilities like HVAC, lighting, and elevators from a single power source.

  • Why: To monitor and manage energy usage, enable cost allocation, and support energy-saving strategies in building operations.

Generator / DG Set Panels

  • Where: AC single source energy meters are used on the output side of Generator / DG Set panels to measure total energy supplied by the generator.

  • Why: To track generator energy output for fuel efficiency analysis, usage monitoring, and accurate operational cost assessment.

Commercial Sub Metering / Retail Malls

  • Where: AC single source energy meters are used in individual tenant panels and common area panels of retail malls to measure energy consumption from a single supply line.

  • Why: To enable accurate tenant-wise energy billing, monitor usage trends, and promote efficient power management.
