BMC Training provides on 18 Nov 2018 Power Systems Protection - Control and Stability course [Electrical and Power Engineering Training] in Paris,France

Course Description

This course has been designed to give plant operators, electricians, and field technicians and engineers a better appreciation of the role played by Power System Protection systems. An understanding of power systems along with correct management will increase your plant efficiency and performance as well as increasing safety for all concerned. The course is designed to provide excellent understanding on both a theoretical and practical level. The course starts at a basic level, to ease the engineer and technician into the perhaps forgotten art of studying, and provide a refresher to those who are more familiar with the basic topics covered. The course then moves onto more detailed applications.

The course features an introduction covering the need for protection, fault types and their effects, simple calculations of short circuit currents and system earthing. The course also includes some practical work, simple fault calculations, relay settings and the checking of a current transformer magnetisation curve.
