Although this project can bring revolution in power transmission and generation system of Pakistan but still there is a room of improvement like installment of infrared sensor with transformers for security, cooling and heating of transformers, better monitoring transformers with a technology better than GSM, as sometimes GSM signals can cause problem in hilly areas, Monitoring of each individual load and much more. e have just presented a concept and taken a step towards improvement of monitoring of transformers and fulfilling load re!uirements. And afterwards we have practically implemented this concept to present a model. "here can be much improvement in this as improvement is nature. Project Description here are two 'ategories of ap 'hanging as underMa/"a(i/al .ap 2"a(-i(-: ap changing of transformers can be done mechanically but this is very uncommon as their switching speed is very slow because they have to move their contacts physically proportional to voltage correction per second. %o if voltage correction is high, they will take more time to correct voltage. Moder( .ap 2"a(-i(-: As we have know that #echanical tap changer has many disadvantages like slow speed, heavy si*e etc. therefore modern technique is to use electronic or solid state device for tap changing of transformer.
