MULTIFUNCTIONAL THREE-PHASE ELECTRICITY METER
|
|
|
|
| |
 |
CE301Mcase modification R33 |
|
|
|
|
CE line multifunctional three-phase electricity meter is equipped with two covers (for board and DIN-rail mounting). Meter measures active energy of in three-phase four-wire alternative current circuits in one direction. Integration in AMR system by means of remote data collection via digital interface, external communication modules and optical port.

Metering and indication of: - consumed active electric energy with progressive total separately and in total under 8 rates by the end of the month and for 13 previous;
- consumed active electricity with progressive total separately and in total under 8 rates by the end of the day and for 45 previous days;
Possibility of setting the following parameters:
- meter serial number;
- current time and date;
- summer time switch (with the summer and winter time switch months setting)
- up to 16 season beginning dates;
- up to 12 daily rating graph zones and up to 12 rating graphs;
- up to 32 exceptional days (days when rating is different and is set by the costumer)
- power and consumption limits under each rate.

- Inbuilt clock accuracy 0,5 sec. per day.
- Storage of consumer settings for not less than 16 years, clock rate and calendaring for not less than 10 years in case of external supply voltage absence.
- 6 Logs event in twenty notes and two logs event in forty notes
- Metering accuracy while changing current direction in phase current circuit.
- Load control with protective cutout device (or external switching device) on dispatch operator command with shutdown mode indication.
- Data and program memory protection against unauthorized changes with the help of buttons or via interface (two password for two access levels, access protection (button or another device), electronic sealing with fixation in event log).
- Data display on LCD with set periodicity (T=5) or browsing with the help of control elements (button) on the front panel.
- Power supply from both phase (1 phase) and phase-to-phase (zero wire disconnection) voltage.
- Ability automated calibration and verification of all measured and metered parameters with the help of digital interface.
- Power and consumption limits deviation alarm.
