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
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.
