Smart Demand Controller

The Smart Demand Controller, with its prediction and control output features, enables demand control and optimization.

EM 3460

Monitoring of Voltage - phase to phase, phase to neutral - average and phase wise, Neutral to Earth voltage
Monitoring of Current - phase wise and average
Phase Angle - voltage and current - phase wise
Monitoring of all power & energy parameters - total as well as phase-wise
Records 4 High's and low profiles for instantaneous and demand parameter with day, date and time of occurrence
TOU for 8 intervals & 7 seasons for energy & demand parameters
EB Meter Cross-check
Monitors demand parameters: Instantaneous & maximum demand, with day, date & time
Synchronizes automatically with EB meter
Generates Demand Profile at 19 Demand Levels for setting realistic demand targets according to user-programmed Demand Level 0 and step size
User programmable upper limit and lower limit of kW or kVA parameters, essential load and prediction interval for sophisticated demand control
Demand control through unique predictive technique and sliding window integration which leads to: Reduced energy losses, improved load factor & minimal disruption in operations
Demand intervals selectable from 1 to 30 minutes
3 change over potential-free control outputs for: Predicted demand exceeds target, demand exceeds target & restore load
Spare load and predicted demand parameters gives advance warning for planned demand control
