Distribution Transformer Integrated Monitor

It is able to realize working status supervision, electricity measure, reading meter for public distributor transformer and can communicate with main station through GPRS/CDMA data channel to form distribution transformer measure management system. Meanwhile, it is compatible of communication regulation of negative control system, and matches large customer power load management system to realize comprehensive management for public transform and special transform.

●AC Sampling: Sampling input voltage spec is three-phase three-wire (3×100V) or three-phase four-wire (3×220/380V or 3×57.7/100V, current specs: 3×1.5（6）A.

● Terminal Reading: Support DL/T－645, IEC1107 and meter regulation that applied widely. The terminal supports at least two kinds of regulations for connecting meter.

● Data Statistics and Processing: Statistics and analysis of load rate (account real time load rate and daily maximum load rate), reliable power supply, unbalanced current rate, daily extremum, voltage quality eligible rate.

● Far Distance Communication: Support GPRS/CDMA mode, realize data communication from far distance; adopt module design in circuit of communication part. It is able to be replaced during power on, convenient for maintenance.

●Record Affair Alarm Actively: Record programmed affairs, reset demand, power off information and abnormal alarm affairs, report actively. When the terminal tests abnormal circumstances in itself or connected meter circuit, it will report to main station. Main alarm affairs include voltage reverse phase sequence, current anti-polar, terminal power off, power on, overload, over-current, overvoltage, undervoltage, unbalance current error alarm, etc.

● Program Upgrade from Far Distance: Terminal supports main station; utilize communication passage for upgrading terminal software and communication regulation from far distance automatically.
