Distribution Transformer Monitoring System
Distribution transformer monitoring system (DTMS) is composed of data monitoring terminal and main station server. It monitors various state parameters of distribution transformer through terminal and transmits information to main station through GSM, GPRS or Wireless, realizing the mass management function of the distribution transformer, such as energy management, remote data acquisition, peak load management, energy accounting, transformer health monitoring, remote switching, etc. Ensuring the transformer's health and power supply stability.
