COURSE OVERVIEW:

The safe operation and continuous availability of switchgear assemblies are fundamental to the reliability of any power distribution network. This course provides a technical framework for the management of Low, Medium, and High Voltage switchgear, focusing on the mechanical and electrical interactions that occur during switching operations. Participants will explore the mechanics of "Arc Extinction" and the structural design of "Metal-Clad" versus "Gas-Insulated" (GIS) systems.

The scope of this training addresses the full spectrum of operational tasks, from routine "Racking" and "Switching" to the execution of detailed preventive maintenance schedules. It covers the technical nuances of various insulating media, including air, oil, vacuum, and SF6, and the specific maintenance requirements for each. The curriculum provides a detailed focus on the secondary control systems, ensuring that participants understand the interlocking logic that prevents dangerous operational errors.

Coverage includes the implementation of diagnostic testing techniques such as insulation resistance, contact resistance, and timing analysis. Attendees will learn to identify signs of equipment distress, manage "Arc Flash" risks during operation, and troubleshoot common mechanical and electrical malfunctions. By combining theoretical engineering with practical site-based maintenance routines, the course equips professionals with the expertise required to maximize the lifespan and safety of their switchgear assets.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Define the primary functions and classifications of modern switchgear.
• Identify the mechanical components of the circuit breaker "Operating Mechanisms."
• Execute safe "Racking-In" and "Racking-Out" procedures for MV/LV breakers.
• Explain the physics of arc quenching in Vacuum, SF6, and Air media.
• Perform "Contact Resistance" (Ductor) testing to verify current path health.
• Execute "Insulation Resistance" (Megger) tests on busbars and breakers.
• Perform "Breaker Timing" analysis to verify opening and closing speeds.
• Maintain and lubricate "Spring-Charging" and "Latch" mechanisms.
• Troubleshoot "Fail-to-Trip" and "Fail-to-Close" electrical control faults.
• Utilize "Infrared Thermography" to detect high-resistance connections.
• Manage "SF6 Gas Quality" and monitor for gas leakage.
• Implement a "Condition-Based" maintenance plan for aging switchgear.

TARGET AUDIENCE:

This course is intended for Electrical Technicians, Plant Electricians, Substation Operators, and Maintenance Supervisors.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximize the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
