Terminal Connection

Applications and Industries where it is used

Electrical Panel

  • Where: Watt and kilowatt meters are used in main LT panels and distribution panels to measure active power consumption of connected electrical loads.
  • Why: To monitor real-time power usage, support energy audits, and optimize load distribution for efficient energy management.

Building Management Systems (BMS)

  • Where: Used in BMS panels to measure the active power consumption of HVAC systems, lighting, and other building services.

  • Why: To track energy usage, enable accurate load profiling, and support efficient energy management and cost control.

Generator / DG Set Panels

  • Where: used on the output side of Generator / DG Set panels to measure the real-time active power delivered to the load.

  • Why: To monitor generator load, prevent overloading, and ensure optimal power generation efficiency.

Commercial Sub Metering / Retail Malls

  • Where: Watt and kilowatt meters are used in individual tenant panels and common area sub-metering panels in retail malls to measure real-time power consumption.

  • Why: To ensure fair energy billing, monitor usage patterns, and support energy efficiency initiatives across different zones or tenants.
