Traceable Watt-Hour Test Pulse for Accuracy Certification
To be certified for revenue metering, power providers and utility companies need to know that the billing energy meter will perform to its stated
accuracy. To verify the meter's performance and calibration, power providers use field test standards to ensure that the unit's energy measurements
are correct. Since
the EPM 6100 submeters are traceable revenue meters, they contain a utility grade test pulse allowing power providers to verify and confirm that the
meters are performing to their rated accuracy. This is an essential feature required in all billing grade meters.
Utility Peak Demand Metering
EPM 6100 submeters provide user-configured Block Window or Rolling Window Demand. This allows customers to set up a particular utility demand
profile. Block Window Demand is demand used over a fixed user-configured demand period (usually 5, 15 or 30 minutes). Rolling Window Demand is a
fixed window demand that moves for a user specified sub-interval period. An example is a 15 minute demand using 3 subintervals, providing a new
demand reading every 5 minutes based on the last 15 minutes. Readings for kW, kVAR, kVA and PF are calculated using utility demand structures.
Other parameters offer max and min capability over the user-selectable averaging period. Voltage provides a non-rolling instantaneous max and
min reading, displaying the highest surge and lowest sag seen by the meter.
