2.1.5: Utility Peak Demand
The Shark® 100/50 meter provides user-configured Block (Fixed) Window or Rolling
Window Demand. This feature lets you set up a customized Demand profile. Block
Window Demand is demand 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 subinter-
vals and providing a new Demand reading every 5 minutes, based on the last 15 min-
utes.
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.
