Mercury 238 ART

— The meters have split architecture (split-meter) and are equipped with a remote display for remote reading.

— The remote display receives data from a meter via a radio channel simultaneously and independently of data exchange between the meter and an AMR/AMI system.

— Metering, storage and transfer via interfaces active and reactive electrical energy individually by every tariff and cumulatively for all tariffs for the following periods of time:

• total cumulative energy;
• energy at the beginning of the current day and 123 previous days;
• energy at the beginning of the current month and 36 previous months;
• energy at the beginning of the current year and the previous year;
• consumption for the current day and previous day;
• consumption for the current month and 11 previous months.

— Metering of reactive energy by every quadrant in bidirectional meters.

— TOU with the option of setting individual schedule for every day of the week and month based on 4 tariffs, 16 time zones per day (24 time zones per day in meters with a DLMS/COSEM, SPODES protocol). Individual tariffs schedule is set every month. Minimal interval of each tariff during 24 hours is 1 minute.

— Measurement of technical losses in power lines and power transformers.

— Measurement of electrical network parameters

• instantaneous values of active, reactive and total power for each phase and the sum of phases with the total power vector direction indication;
• RMS of phase currents and voltages including measurements at one period of frequency for power quality analysis;
• phase angles;
• power frequency;
• power factors of each phase and of their sum;
• THD of sinusoidal phase lines.

— Two independent power profiles with integration period from 1 to 60 minutes, the second profile can be configured as a technical losses power profile.

— The storage period is 170 days for 30 minutes averaging time.

— Recording of morning and evening peaks of active and reactive power at a specified interval from 1 to 60 minutes with a monthly schedule.

— Event logging including power quality events.

— Built-in optical port in all models.

— Optional built-in interfaces: PLC, RF, LoRaWAN.

— Automatic self-diagnosis with error indication on remote display.

— Built-in 100A relay.

— Two nonvolatile electronic seals.

— Magnetic field sensor. 

— Recording of unauthorized impacts into the indelible event log.

— DLMS/COSEM and Mercury protocols support.

— Meters have solid housing and transparent terminal cover for prevention from tamper.
