Overview
Demand Measurement and Control
- W, Var, VA and Current Demand
- Controlling with any selected parameter
- Selectable window type – Fixed or Sliding
- Demand Period selectable from 1 to 60 minutes
- Predictive Demand Control for faster controlling action even before completion of present demand interval
- Demand Control with separate load shedding thresholds for each tariff zone
- All Max Demand (W, VAr, VA & Current) parameters are stored with Date and Time stamp
- OLD Max Demand Storage
Control Outputs
- 4Relay Outputs for efficient Demand Control and Management
Measures & Monitors more than 80 parameters
- All basic electrical parameters
- Individual harmonics contents of per phase voltage and current.

True RMS measurement
The instrument measures distorted waveform upto 56th Harmonic for 50Hz and upto 46th Harmonic for 60Hz
Power Quality Measurement
- Measurable up to 56th (50Hz) harmonic on each phase. Maximum any 6 harmonics can be monitored simultaneously for each phase
- Measurement of RMS value of fundamental and per phase voltage and current harmonics
- (%) THD of per phase voltage and current
- Distortion factor of individual harmonics
Real Time Clock (RTC)
Displays date and time
Run Hour, ON Hour, Number of Interruptions
Displays parameters for both mode utility and generator.
Graphical Analysis
