Operation

Energy Measurements in all four Quadrants total 8 different energy resisters like Import/Export and LAG/LEAD. - Four Feeder Control relays with Programmable TOD, 8 TOD definition per feeder. - Battery back up: Meter will work for at least 3 days in absence of power for data downloading by pressing key.

Tamper protection & detection

Voltage circuit : Voltage unbalance, Phase seq. error Current circuit : CT Reverse Neutral circuit : neutral missing

Interface

Display : Custom LCD - 62mm x 66mm size; 7-segment-12mm (High Resolution Display) Outputs : 4 nos. relay outputs for feeder and 1 relay for GPRS Modem, with potential free contacts rated at 3 Amps, 250V AC Inputs : 1 no. digital input rated at 24VDC Communication : RS232 Port/ RS 485 and Optical port/Blue tooth AMR : AMR compatibility (GSM/GPRS), Remote configuration : Supports downloading of system parameters and Logged data

Miscellaneous

  • Energy measurement in all four quadrants. Total 8 different energy registers like Import/Export and lag/lead.
  • RS232 port for external modem for GPRS connectivity with EMON at base station.
  • Bluetooth data downloading is reduced to 2M Bits for load survey and other required data for easy data downloading through Bluetooth enabled laptop or Bluetooth Hand Held Device
  • Load survey data with 48 logs per day and for the last 30 days. Log includes all the parameters like rising demand, all quadrant energies and Power
  • Battery Backup: Meter will work for at least three days in absence of power. Readings can be taken even without power, at the press of a key. Inbuilt battery charger to charge battery in presence of power.
  • Logs 100 power down, 100 power up and 250 tamper events like CT reversal, phase sequence error, neutral missing/ neutral imbalance with all three phases, voltage imbalance, magnetic switch. Tamper event will also have a electrical system snap shot
  • Fixed window based KVA and KW Max Demand for the running month for both Import and Export.
  • Record of last 12 months MD for Import/Export, phase wise average PF of the month for both Import and Export. Minimum - maximum values for 3 phase voltages and currents and all energies.
  • Record of last 120 days all energies and on time of feeder control relays in minutes.
