The main function of
(1) distribution transformer monitoring: voltage, current, the voltage qualification rate, harmonics, flicker, transient overvoltage.
(2) protection of distribution transformer: undervoltage, overvoltage, overload, overheating protection
(3) electric information monitoring user: the user electric meter data
(4) summary of distribution transformer monitoring: meter data and running status table area
(5) residual current circuit breaker monitoring: residual current monitoring, state of residual current
(6) monitoring: terminal operation temperature, gas concentration, incoming and outgoing line switch, switch, transformer
(7): power load management custom closed-loop control, power set point control, remote control
(8) the power quality management: no dynamic reactive power compensation, three-phase unbalanced governance, harmonic control
(9) the safety protection: anti-theft alarm, abnormal information
(10) the communication function: GPRS uplink, downlink carrier
(11) the interaction management: handheld field management, local RS232 communication management.
