PATH: ACTUAL VALUES ÖØ A2 METERING ÖØ DMND
The relay measures current demand on each phase, and average three phase demand for real, reactive, and apparent
power. These parameters can be monitored to reduce supplier demand penalties or for statistical metering purposes.
Demand calculations are based on the measurement type selected under S6 MONITORING ÖØ DMND. For each quantity, the
relay displays the demand over the most recent demand time interval, the maximum demand since the last maximum
demand reset, and the time and date stamp of this maximum demand value. Maximum demand quantities can be reset to
zero with the
S1 RELAY SETUP ÖØ CLEAR DATA ÖØ CLEAR MAX DMND DATA setpoint command.
