Review on GSM Based Substation Monitoring System

Transformers are a vital part of the transmission and distribution system. Monitoring transformers for problems before they occur can pre-vent faults that are costly to repair and result in a loss of service. An innovative design to develop a system for monitoring the voltage, current and temperature, oil level, theft of a distribution transformer in a substation and to protect the system from the mentioned parameters based on GSM that is used in this paper. Providing the protection to the distribution transformer can be accomplished by shutting down the entire unit with the aid of the Radio frequency Communication. This mobile system will help the transformers to operate smoothly and identify problems before any catastrophic failure. Moreover the system displays the same on a PC at the main station which is at a remote place. The proposed design is developed for the user to easily recognize the distribution transformer that is suffered by any problems.
