Advanced Training on Interpretation of Dissolved Gas Analysis of Transformer Oil

Introduction

The dissolved gas-in-oil analysis is by far the most frequently requested diagnostic test and the single most important test performed on transformer oil. As the insulating materials of an electrical apparatus, such as a transformer, break down from excessive thermal or electrical stress, gaseous byproducts form. The by-products are characteristic of the type of incipient-fault condition, the materials involved, and the severity of the condition. Dissolved gases are detectable in low concentrations (ppm level), which usually permit early intervention before the failure of the electrical apparatus occurs, and allow for planned maintenance.

Objectives

    By the end of the training course, participants will learn to:

    • Transformer types and cooling systems
    • Oil-filled transformers
    • Dissolved gas analysis
    • Oil level indicators
    • Transformer oil test
    • Key gas methods

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?

Electrical engineers, Instrument engineers – Operations and field engineers, Maintenance engineers.
