Training on Introduction to Industrial Electrical Systems at L & T Switchgear Training Centre- Report

 A 3 days training programme on “INTRODUCTION TO INDUSTRIAL ELECTRICAL SYSTEMS” was conducted at L&T Switchgear training centre – Connoor from 27th September '15 to 29th September '15 for Batch I and 30th septembet to 2nd October for Batch II
Totally 63 participants, 59 students including 4 staff members attended this training.

On Day 1  the session starts with a brief introduction about Low Tension switchgear – A device that is a combination of devices primarily intended for the purpose of making, carrying and breaking current in electric circuits under normal as well as abnormal conditions.They deals with the different types of switches and switch gears and their applications.In workshop session, deals with real time operation of contactors such as quenching, humming and chattering.

On Day 2  the sessions consists of factors leading to overheating in electrical equipments, devices for motor protection, selection procedure for thermal over load relays that employs in protection and the action performed while tripping of relays. Starter for 3 Phase induction motor, such as DOL starter,Star-Delta, Auto transformer starter. The work shop session followed by the class room session made a clear picture on the real time operation of relays, starters and contactors.

On Day 3 the sessions consists of protection devices for motor such as MCB and MCCB in the class room session as well as in the work shop session. In the workshop session, gives the detailed idea about ACB (Air Circuit Breakers) and HRC (High Rupture Capacity) fuse links.They demonstrate different kinds of ACBs (manual,motorized etc) and different kinds of HRC fuses (f type,bolted and plate type).The session ends with a small objective type test followed by certificate distribution.
