Applications and Industries where it is used

Electrical Panel

  • Where: Used in main LT panels and distribution panels to monitor multiple electrical parameters like voltage, current, power, power factor, frequency, and energy.
  • Why: To provide comprehensive real-time monitoring for efficient load management, fault detection, and energy optimization.

Building Management Systems (BMS)

  • Where: Used in BMS panels to monitor electrical parameters of key building systems like HVAC, elevators, and lighting across all three phases.

  • Why: To enable centralized energy monitoring, detect anomalies, and ensure efficient operation of building infrastructure.

Generator / DG Set Panels

  • Where: Used on the output side of Generator / DG Set panels to monitor voltage, current, power, power factor, and frequency across all phases.

  • Why: To ensure balanced load distribution, prevent generator overload, and maintain stable power quality during operation.

Commercial Sub Metering / Retail Malls

  • Where: Used in tenant and main distribution panels of commercial sub-metering systems in retail malls to monitor comprehensive electrical parameters for each zone or tenant.

  • Why: To enable detailed energy monitoring, ensure balanced load usage, support accurate billing, and enhance overall power management.
