Demand Limit Exceeded Application
Alarm
UtilityMonitoring The application will provide an application alarm to
signal a high demand. The demand alarm limit and
alarm delay should be configurable. The demand alarm
delay is the amount of time the application will wait
after the Shed output turns on, before the demand
alarm is generated. Also, the Shed Output may be con-
figured to be controlled by either the average or instan-
taneous usage rate.
