Abstract:  Our project deals with the Power transformer (shortly called G.T) located between Generator and Grid through suitable switch-gears. Here temperature of oil and winding plays the major role and has to be controlled within the limit of PLC may be introduced in the place of present control logic – to start cooling fans (Forced Air Cooling), Oil pumps (Forced Oil Cooling), to monitor oil level, Oil Flow, Buchholz relay – thereby initiating Alarm and Trip signals for related operation and maintenance convenience.

Key Words: 

PLC, temperature, Power transformer, Buchholz relay ,GT
