COURSE OVERVIEW:

The longevity and reliability of an electric distribution network are fundamentally linked to the quality of its preventive maintenance program and the engineering principles applied to its operation. This course provides a comprehensive framework for Electric Distribution System Preventive Maintenance, focusing on the technical requirements for maintaining transformers, switchgear, and cables. Participants will explore the transition from reactive "run-to-fail" approaches to proactive, data-driven maintenance strategies that optimize asset life.

The scope of this training addresses the underlying engineering principles that govern equipment degradation, including thermal aging, dielectric stress, and mechanical wear. It covers the technical nuances of conducting periodic inspections, fluid analysis, and electrical testing to identify incipient faults before they lead to system outages. The curriculum provides a detailed focus on the development of maintenance schedules and the interpretation of diagnostic data to inform asset replacement decisions.

Coverage includes the implementation of advanced diagnostic tools and the management of maintenance documentation in compliance with utility standards. Attendees will learn to conduct root cause analysis of equipment failures and apply engineering solutions to mitigate recurring issues. By combining theoretical knowledge of equipment physics with practical maintenance protocols, the course equips professionals with the expertise required to manage a resilient distribution system that balances cost-effectiveness with high service availability.

COURSE OBJECTIVES:

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

• Design a comprehensive Preventive Maintenance program for distribution assets.
• Explain the engineering principles of insulation and conductor degradation.
• Perform routine inspections and testing of distribution transformers.
• Execute maintenance and timing tests for MV and LV circuit breakers.
• Interpret oil analysis and dissolved gas data for health assessment.
• Conduct thermal imaging surveys to identify high-resistance connections.
• Evaluate the condition of underground cables and overhead line hardware.
• Implement effective maintenance for battery systems and chargers.
• Utilize diagnostic tools for insulation resistance and polarization index.
• Manage the scheduling and documentation of maintenance activities.
• Conduct root cause analysis for distribution equipment failures.
• Ensure safety and regulatory compliance during maintenance operations.

TARGET AUDIENCE:

This course is intended for Distribution Maintenance Engineers, Utility Supervisors, Electrical Technicians, and Asset Managers responsible for network reliability.

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.
