LV/MV/HV Circuit Breakers and Switchgear

Course Introduction

This intensive five-day training 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 maintenance. It must be understood that there is an incredible variety of equipment used on low, medium and high-voltage switchgear today. Switchgear plays 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.

An older plant may have switchgear that was built in the forties in the older areas and modern switchgear in other areas as the plant was upgraded. This course will present maintenance problems to the maintenance manager and technician. Newer plants will have modern equipment of a limited variety and manufacture. It is these similarities that will be covered in the course.

Objectives

By the end of the training, participants will be able to:

• Design, inspect, maintain, repair and troubleshoot circuit and switchgear
• Apply in-depth knowledge and skills on LV/MV/HV circuit breakers and switchgear
• Describe switchgear details such as ratings, degree of protection, service conditions and ancillary equipment
• Explain switchgear asset management including CBM and RCM process, tripping devices, maintenance, and testing
• Apply load and fault calculation to decide the task of protection system and the operating conditions of the power system
• Explain circuit breaker control circuits, types and applications of protective relays, the structure of control circuits and the use and application of current and voltage transformers
• Discuss circuit breaker characteristics in relation to protection control circuits, selectivity, sensitivity, and speed of the control circuits
• Recognize the value of the earthing system to protect control circuits and the power system protection as well as fault clearance and power redundancy through a control system application
• Identify the various switchgear diagnostic techniques and employ the different types of substation circuit breaker techniques and determine the switchgear vital equipment including batteries condition and monitoring, relay applications for basic complex busbar arrangement and zone selection logic
• Employ substation maintenance techniques and discuss their description, structures, features and functions
• Apply the switchgear maintenance practices and improve maintenance and repair procedures
