ENERGY METERS
Three-phase, active/reactive



Mercury 230 ÀR


Meters are designed for registration of active and reactive energy in one direction in 3- or 4-wire networks of alternating current and operate either autonomous or within AMR.

Meters provide:
  • Energy registration by each phase of three-phase network in one- or multi-tariff (switching by interface signals) modes as well total on all phases.
  • Indication on LCD active and reactive energy with growing total from indications reset on each tariff and on tariff sum..
  • Measuring of instantaneous values of active, reactive and full power on each phase ond on phases sum with indication of direction;
  • Measuring by phases: current, voltage, frequency, cos F, angles between phase voltages.
  • Programmable control of external devices of consumer load switching on/off.
  • Transmission of measuring results through power line 220/380V (only consumed energy) and through CAN, RS-485 (all existing data).
  • Meters programming in phases summation mode “by module” to avoid energy theft if meter current circuits connection phasing is wrong.
  • Meter internal clock correction.
Technical specifications
  • Accuracy class 0.5s, 1.0s
  • interfaces: CAN, RS-485
  • measuring network values
  • tariff switching (up to four) is realized with interface signals
Documents
Meters indicate on LCD display:
  • Consumed active and reactive energy value for each tariff (up to four) and total for all tariffs with growing total and accuracy up to hundredth parts of kWh and kVAh;
  • Phase voltage and current in each phase;
  • Measured value of active, reactive and full power (integration time 1 s) both for each phase and total for three phases with indication of quadrant, in which there is a full power vector;
  • Power factor for each phase and total for three phases;
  • Angles between phase voltages;
  • Network frequency;
  • Current date and time
  • Power line modem values
  • Modem signal level sign

Meters provide reading by external PC through interfaces «CAN» , «IrDA» or RS-485 of the following values and data:
