    Energy Metering Overview
    • Tenant Sub-Metering/Cost Allocation
      • Monitoring a tenants Energy consumption within a building with the intent of collecting money for the consumed electricity.
    • Activity Based Costing
      • Monitoring Energy at multiple points and allocating energy costs based on activities within a facility or campus.
        • Example Activities/Facilities include: Production Lines in a Factory and Departments on a College Campus.
    • Performance Monitoring
      • Measuring Energy usage before and after an efficiency upgrade with the intent of seeing a reduction in consumption.
    • Load Shedding
      • Avoiding peak demand charges by reducing your power level during critical times.
      • Demand Response – Cut loads in response to a command from a utility as part of a demand response program.
    • Performance Optimization
      • Determine where your energy is being consumed, monitor the performance of equipment to detect trends and optimize/minimize consumption.
    • Load Aggregation
      • Monitoring of energy at multiple sites separated by geography and using the internet to consolidate data for the purpose of energy management and or utility procurement strategies
    Energy Metering Applications
    • How many phases? – 1,2,3 or 3 + N?
    • What is the voltage?
      • 90 – 600VAC, Is there a Neutral?
    • What is the current range?
      • 100A – 5000A
    • Where will it get installed?
      • Mounted on a wall, embedded in equipment, or panel mounted through a control center?
    • What kind of data do you need?
      • Watts or Watt hours only – Maybe use 4-20mA or Pulse Meter
      • For more power quality info you need a communications interface ( Modbus, BACnet, etc…)

    • How do you determine the metering accuracy of the system?
    Systems Accuracy
  • Typical System Accuracy
    • Stand Alone Meter
    • ANSI C12.20 – 0.2%
    • Stand Alone 100A:5A CT
    • Commercial grade CT –
    • 1.0% FS amplitude error
      • i.e. error is 1A of current
      • At 100A, error = 1%
      • At 50A, error = 2%
      • At 25A, error = 4%
    • Phase error is unknown
  • Typical System Accuracy
    • Worse case accuracies :
      • 100A level = 0.2% + 1.0% = 1.2%
      • 50A level = 0.2% + 2.0% = 2.2%
      • 25A level = 0.2% + 4.0% = 4.2%
    +
  • Typical System Accuracy
    • These are calibrated together at the factory :
      • Accuracy is better than 1.0% at ALL current levels
      • Phase error has been calibrated too!
