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.
Functions
Power Measurement Function
It can execute time-measuring of assembled active power, positive and negative active power, assembled reactive power, four-quadrant reactive power, positive and negative apparent power, as well as copper loss and iron loss power.
Multi-rate function
With two sets of rate time consumption, it can freely transfer these two sets according to the settled time.
Freeze function
Support four freezing methods, namely timing freezing, instantaneous freezing, agreed freezing and day-time freezing.
Power demand measuring function
It measures maximum demand of positive and negative active power, as well as the occurring time.
Load curve recording
It can execute the scrolling data record of selected data by interval according to the settled time of users. The shortest interval time is one minute.
Power network monitoring functions
Provide monitoring function of exceeding limit. It can set limit value of such parameters as line (phase) voltage, current, and power factor; and can implement monitoring.
Events recording function
Record various events such as loss of voltage, phase failing, loss of current, power failure, voltage (current) reverse phase sequence, programming, power demand clearing, timing record, etc.
Alarm function
It can create sound and light alarm when occurring to such events as loss of voltage, loss of current, reverse phase sequence, overload, reverse power, and battery with less voltage.
Cover-opening recording function
It can record whether it has opened meter cover or terminal cover.
Harmonic measurement function
It can measure 1 to 20 times of the voltage and current harmonic content with each phase.
