| Course Duration : | 5 Days |
| City : | Abu Dhabi |
| Location : | UAE |
COURSE OVERVIEW
Switchgears play an important role in the distribution and control of electrical power in manufacturing or power plant and in a utility distribution system. Negligent maintenance practices can lead to power system inefficiency and loss of system reliability. This course is designed to update participants with the latest development of Circuit Breakers and to present some of the more common and updated aspects of low, medium and high voltage switchgear design, classification, selection, and maintenance.
LEARNING OBJECTIVES
To provide participants with practical techniques and concepts in Switchgears and Circuit Breakers. The course aims at providing the participants with key concepts that will enable them to operate with confidence in a highly changing world in all sectors of the industry. Participants will have first hand experience of new concepts.
