Three phase four wire active energy meter is a induction meters which is applicable to measure 50 Hz or 60 Hz active energy consumption from three phase AC electricity net. All technical targets are completely conformed to National Standard GB/T15283-2008 and International Standard IEC62053-11. It has the features of tight structure design, high overload, low power loss, long service life, specious appearance, etc.
1. Energy Measurement:
Forward, Reversed and the sharp, peak, shoulder and off-peak combination active and reactive energy, Four-quadrant.
2. Frozen Function:
Timing frozen, Instantaneous frozen, Appointed frozen, Daily frozen, Measurement, Period frozen Energy.
3. Demand Record:
MD and time of the total, Sharp, Peak, shoulder, and off-peak of forward and reversed active.
MD and time of the total, Sharp, Peak, shoulder, and off-peak of combination reactive.
MD and time of the total, Sharp, Peak, shoulder, and off-peak of four-quadrant reactive.
Forward and reversed MD and time of the total Phase A, B, C.
Real-time Measurement: Measurement of Voltage, Current, Power, PF and Phase-angle.
Time Interval and Tariff: Four-kind of Tariff supported and two-set period.
4. Event Record:
missing voltage, under-voltage, over voltage, missing phase, completely missing voltage, current/voltage phase sequence reversed, current/voltage imbalance, missing current, cover opened, terminal opened, programming, MD cleared, energy cleared, clock calibration, etc.
Manually reading: reading the data when press the up-button and down-button.
Reading by HHU(Hand Held Unit): reading the data through Infrared by HHU.
PC reading: reading the data by PC with RS485 communication port.
Reading when power off: when the power off, the meter can be woke up by the button, and then the data can be read from LCD display or by HHU automatically.
LCD display with backlight. The data can be display by pressing button or recycle display automatically.
