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!
