COURSE CODE : E-554COURSE NAME : ELECTRICAL INSTALLATION AND MAINTENANCE

1. RATIONALE :

Due to the liberalization policy there is a rise in the establishment of newmedium and large scale industries. Modernisation of old industries are alsoin progress. These industries require highly skilled technicians/ engineersbasically expert in electrical installations commissioning and testing of newlypurchased modern electrical equipment/ machines or process instruments forestablishing new industries and for modernisation of old (running) industries.

The technician should be able to prepare foundation ( proper size and height)for installation of electrical equipment/ machines, meters, process instrumentsetc. He should be able to test various equipments before commissioning andafter commissioning as per specification of machines/ instruments as per I.S.He should carry out electrical and mechanical test and prepare test reports.

He should also have expertise in maintenance of electrical equipments andmachine. Efforts are made to develop these skills in the students through thiscourse.
