Condition Monitoring of Power System Equipment

Introduction

Faced with increased demands and growing competition, many utilities and industries are seeking to maximize the value of their existing assets by leveraging new technologies to optimize Operations and Maintenance activities. One of the most successful maintenance strategies is a conditioned-based approach that utilizes data collected from periodic inspections, testing and predictive maintenance technologies to determine the optimum maintenance requirements.

Contrary to the traditional time-based maintenance approach, Condition-based Maintenance is a process, which utilizes monitoring and diagnostic data to drive the maintenance decision process 

Objectives

    • At the end of this course, the electrical power engineers will be equipped with a better understanding of what to do, when to do it and how to interpret the results from on- and off- line diagnostic tests on Cables, Switchgears and Transformers. In effect, utilities and industries may avoid expensive failures and unscheduled outages, and most importantly, personal injury.
    • Understand typical failure modes associated with Cables, Switchgears and Transformers.
    • Understand typically used on- and off- line diagnostic tests for condition monitoring of Cables, Switchgears and Transformers.
    • Understand the interrelationships of various on- and off- line diagnostic tests.
    • Understand the interpretation of test results.

Training Methodology

This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations. The online course is conducted online using MS-Teams/ClickMeeting.

Who Should Attend?

This course is specially designed for Engineers and Technologists dealing with Operation, Maintenance & Testing of Switchgears, Cables, and Power Transformers.
