Wireless expounding of voltage, current, temperature, gas in transformer

High voltage power transformer is extensively operated in the generation of electrical energy in either voltage stepping up or stepping down condition. The additional attachments namely breather, cooling fan, bushing, differential relay, Buchholz relay are synchronized with the transformer operation. It is essential to estimate the troubles occurring in it and to expound them as soon as desirable, so the high cost transformer does not get destructed and also helps in maximum use of it. Here it targets how to decrease and determine them in effective way. In this paper a tryout has been made of detailed use of system and wireless automated transmission system for guarding and ideal use of High voltage transformer. Programmable logic controllers (PLC) can be serviced for supervision & wireless transmission of transformer. The important logic is cost constraint and smarter use. Programming the PLC helps in achieving the various functions and controls. PLC can be used for complete wireless power plant control including superintending and auto-operation that includes cooling fan, transformer oil leakage and oil level control, automatic ON/OFF of pump, restoring of Buchholz relay by pressure sensor control, ON/OFF of secondary systems, and protection etc. Tasks other than supervision like continuous analyzing, data report, instrumentation and stability can also be achieved. For inaccessible working, transmission with PLC can be implemented. For uninterrupted monitoring purpose, a PC can be linked with PLC and connected data can be monitored regularly.
