Electrical Power Systems

Description

Electrical Power Systems which divided for 3 main components:

Switchgear

Switchgear plays an important role in electricity distribution and its performance significantly affects the overall performance of the system. Failure to efficiently disconnect faults elsewhere in the network or failure in switchgear itself is costly, resulting in additional loss of supply, damage to equipment and possibly fatal injury to personnel.

Learning Objectives

• Develop fundamentals & performance of LV & MV switchgear.
• Understanding the operation & Maintenance of switchgear and circuit breakers
• Understanding the proper installation of Switchgear
• Testing Procedures of switchgear and circuit breakers
• Understanding Condition Based Maintenance (CBM)
• Understanding Partial Discharge Measurements
• Understanding the deference between Preventive and corrective Maintenance
• How to perform tests on Circuit Breakers
• How to perform tests on Bus bar
• How to perform tests on Bus Ring Main Unit
• Know the methods of system earthing and protection requirements.
• Examine the differences between switchgear and switchboards
• Understanding of LV panel form
• Understanding Ingress Protection

Power Cables

Power Cables are critical components in utility distribution systems and power plant, their performance significantly affects the overall performance of the system and playing very important role in network reliability.
