TRANSFORMER HEALTHCARE MONITORING AND CONTROLLING SYSTEM

Electrical Engineering

Transformers are a vital part of the transmission and distribution system. Monitoring transformers for problems before they occur can prevent faults that are costly to repair and result in a loss of service. Current systems can provide information about the state of a transformer, but are either offline or very expensive to implement. Transformers being the essential part of power transmission system are expensive, as is the cost of power interruptions. Because of the cost of scheduled and unscheduled maintenance, especially at remote sites, the utility industry has begun investing in instrumentation and monitoring of transformer. On-line transformer diagnostic using conventional technologies like carrier power line communication, Radio frequency based control system, and supervisory control and data acquiring system, Distributed control system and Internet based communication are having their own limitation. GSM is transmitting voice and data services. This Project objective is to develop low cost solution for monitoring and controlling of remotely located transformer using GSM technology to failure of transformer and increasing reliability of services to the consumer. A hardware design is developed to acquire data from electrical sensing system. It consist of a sensing system , signal conditioning electronic circuit, advanced hardware for middle computing, a powerful computer network for further transmitting data various places. Any change in Parameter of Transmission is sensed to protect the entire transmission and distribution. This model developed is tested at laboratory for measuring various parameters like over load, over temperature, voltage fluctuation, oil level etc.
