What are the key elements of a power monitoring system?

Power monitoring systems include: metering devices (power meters at key points measuring V, I, kW, kVAR, kWh, PF), communication network (Modbus, BACnet, or Ethernet), software for data collection and analysis, and user interface for real-time monitoring and reporting. Benefits include energy cost tracking, demand limiting, power quality analysis, and predictive maintenance. Strategic meter placement at main service, major feeders, and large loads provides visibility for energy management.
