Report on Substation Equipment Manufacturing

Abstract

This report is written on the basis of our visit to Energypac and all the technical details we were introduced to during our visit. The technical content of our visit was centered on Substation equipment's that are divided into four parts. These parts are transformer, switchgear, breaker and locator and instrument transformer (CTIPT). In this report we also talk about the manufacturing access of these equipment. transformer is a device that can transfer energy one circuit to another by electromagnetic duction. Basically the main part of transformer is core and coil. Core is made by using different tape. This shape is cut by auto core cutting machine and this shape together the core is created. The raw material is silicon steel sheet. The coil has two parts one is LT (low tension) coil and HT (high nsion) coil. The raw material of HT coil is disc coil and LT coil is spiral coil. By using core inding machine coil is created. Then by assembling the core and coil it tank up. For insulate the stem insulation oil, insulation paper etc are used. After adding and other parts the transformer is introduce. Energypac manufacture three types of Isolator. Pantograph, Centre break and Double pak. Pantograph is four point contacts. It opens all contacts when breaking. Centre break is three contacts and Double break is two pole contacts. Vertical or Horizontal terminal take off.
