Application
CL760 series energy distribution transformer management terminal monitor the transformer, power distribution wire running status, compensate power distribution network reactive function. This terminal applies the advanced GPRS communication system. It can read the meter and can be used for many kinds of remote meter reading. It is applied to monitor low voltage network status and low voltage dynamic status compensation.
Functions
Real-time collect the data of three phase voltage, current, neutral line current, active and reactive power and power factor; forward active total energy, reactive energy; and ABC three phase voltage aberrance rate; instantaneous reactive and active energy. (second side)
Load Statistic: The Max.(min.) Current and voltage value and Occur time; voltage beyond range time; three phase average current Max. value and occur time of each 15mins.; capacitance switch time.
Reactive compensation is based on reactive, voltage and voltage aberrance rate to make the capacitance switch on and off; analyze the setting parameter to control capacitance switch on and off, to realize reactive compensation and active balance at once.
Record the event of power off, compensate capacitance failure, revise energy data; statistic the voltage beyond range time and voltage eligibility time; record on site parameter when event occur.
Online check the oil temperature, oil mark position; online monitor the capacitance switch by group information, monitor the power factor, voltage, reactive power before and after switch.
The clock still work at power failure, all the data is saved automatically except real time data, the storage is 2 MB, and the data can be saved for at least 10 years.
It have report function when events occur, it can report via SPRS and SMS.
Features
