Electricity meter three-phase microprocessor multifunctional universal CE301-S31

Three Phase Multifunctional Electric Meter series "CE". Mounted on the shield. Measures and records active electric energy in three-phase four-wire AC circuits with the possibility of metering in one or two directions. The meter has the ability to organize multi-tariff electricity metering with the transfer of accumulated information via an optoport, RS485, RF433, PLC or GSM / GPRS modem interface. Counter provides * The possibility of manual correction of the clock ± 30 s / day once a day. The accuracy of the built-in clock 0.5 seconds / day. * Preservation of calculated indicators and user settings for at least 16 years, and the clock and calendar maintenance for at least 10 years with no external supply voltage. * Fixing the last 20 time adjustments, changing the settings of the temporary tariff zones and reprogramming the meterological characteristics of the meter. * Fixation of the last 100 disappearances and exceeding the permissible values of phase voltages. * Accuracy of measurements when changing the direction of the current in the phase current circuit. * Load control using external switching device * Protection of data memory and program memory from unauthorized changes using buttons or interface (two passwords for two access levels, hardware permission (button or other device), electronic seal with fixation in the event log). * Indication of data on the LCD display with a specified frequency (T = 5-255 sec.) Or scrolling using the controls (buttons) on the front panel. * Power supply from both phase voltage (presence of 1 phase) and linear (break 0). * Ability to automatically calibrate and check all measured and considered parameters using digital interfaces. * Reduction of all data on energy and power to the primary values, taking into account the coefficients of the measuring transformers. * Signaling of deviations from limits on power and consumption. * Monitoring of phase and zero wire breaks in the line sections from the transformer substation to the meter, with subsequent signaling of power line accidents (in the versions of meters with a GSM module). * The task of limits on the excess of consumed currents, with a fixation in the event log and an alarm about the excess of the upper limit. Regulatory support * GOST 31818.11-2012 (IEC 62058-11-2012) * GOST 31819.21-2012 (IEC 62058-21-2012) * GOST 31819.22-2012 (IEC 62053-22: 2003) * Certified and entered into the State Register of Measuring Instruments of the Russian Federation. Reliability characteristics * Average time between failures - 220,000 hours. * The verification interval is 16 years. * Average service life - 30 years. * Warranty period (shelf life and lifetime of the total) - 4 years from the date of issue. Functionality * The meter provides accounting and output to the display: -the amount of active energy consumed by cumulative total and separately for 4 tariffs at the end of the month, for 13 or 12 previous months; -the amount of active energy consumed by cumulative total and separately for 4 tariffs at the end of the day for 45 days; - schedules of active capacities (consumption), averaged over a given time interval of 60 minutes at least 148 days; network parameters; - the maximum value of active power for the current and the past 12 months separately for the four tariffs. The counter provides the following parameters: * current time and date; * resolution of the transition to "summer time" (with the task of months * transition to "winter", "summer time"); * up to 12 dates of the beginning of the season; * up to 12 zones of the daily billing schedule and up to 36 billing schedules; * up to 32 exceptional days (days in which charging differs from the general rule and is set by the user); * current and voltage transformation ratios; * limits on consumption and power with a percentage of excess for the operation of the alarm for each tariff. List of AIIS KUE of third-party manufacturers, adapted for operation with a CE301 counter Features of the meter * Optical interface. * Interface RS485, RS232, radio RF433, PLC, GSM / GPRS modem. * Electronic filling. * Load control relay using or external switching device. * Alarm relay exceeding consumption limits. * Low own energy consumption. * Resistance to climatic, mechanical and electromagnetic influences.
