e) APPARENT POWER DEMAND
PATH: SETPOINTS ÖØ S6 MONITORING ÖØ DMND ÖØ APPARENT PWR
The apparent power demand is monitored by comparing to a pickup value. If the apparent power demand pickup is ever
exceeded, the relay can be configured to cause an alarm or signal an output relay.
For the THERMAL 90% RESPONSE TIME setpoint, enter the time required for a steady state apparent power to indicate 90% of
the actual value. This setpoint allows the user to approximately match the response of the relay to analog instruments. For
the
TIME INTERVAL setpoint, enter the time period over which the apparent power demand calculation is to be performed.
For the APPARENT PWR DMND PICKUP setpoint, the power quantities auto-range to show units appropriate to the power sys-
tem size.
