Duration 5 Days
Introduction
The duty of the switchgears is to switch on and off and to control, once or repeatedly several times, different electrical circuits during normal as well as abnormal operating conditions. Short circuit current level and the behavior of the circuit during transient condition are very essential to select proper specification of switchgears. Good practices and knowledge of circuit breakers and switchgears specification, operation, testing and maintenance are fatal for those engineers and technicians concerning with electrical power system and industrial application.
This course designed to provide the participants with technical knowledge, practical experience and good skills in selecting the proper ratings, maintenance instruction and control procedures of HV & MV & LV switchgears.
Who Should Attend
The course is designed to Highly Qualified Technicians whom concerning with Circuit Breakers and Switchgears in Electrical Utilities, Electrical Distribution, Transmission and Industrial Application.
