2.1.5: Utility Peak Demand
The Shark® 100 meter provides user-configured Block (Fixed) Window or Rolling Window
Demand. This feature allows you to set up a Customized Demand Profile. Block Window Demand
is demand used over a user-configured demand period (usually 5, 15 or 30 minutes). Rolling
Window Demand is a fixed window demand that moves for a user-specified subinterval period. For
example, a 15-minute Demand using 3 subintervals and providing a new demand reading every 5
minutes, based on the last 15 minutes.
Utility Demand Features can be used to calculate kW, kVAR, kVA and PF readings. All other
parameters offer Max and Min capability over the user-selectable averaging period. Voltage
provides an Instantaneous Max and Min reading which displays the highest surge and lowest sag
seen by the meter
