Description

Dear All,

Welcome to the course of understanding schematics of “Motor Control Circuits”.  This course covers from very basic concept of drawings / schematics. Training start with explaining the devices used in schematics, auxiliary relay, contactor, timer, etc. It is ensured that anyone with minimum to no experience in schematics learning can learn and master the skill.

Trainer have over 18 years of field experience and has worked at 11/132/220/500kV Substation, 1263MW power plant, 660kV HVDC system.  worked with several companies, SIEMENS, ABB, GE, SEC, KE, WAPDA, NTDC, ARAMCO, SABIC, MARAFIQ. Trainer has given hundreds of trainings online and offline, so it will be great to join this training and take advantage of field experience.

Topics covered in this training are as follows,

Understand basics of Schematics

Auxiliary Relays

NO & NC Contact of Relays

Contactors

Power & Aux contacts of contactors

Difference between Contactor & Aux Relays

Simulation of Aux & Contactor

Early Make, Late Break Contacts
