An Intensive 3-day Training Course
Dissolved Gas Analysis (DGA) of Transformers and Oil-Filled Cables
Merits, Significance and Impacts of Dissolved Gas Analysis
CLASSROOM DATES
INTRODUCTION
Transformers are critical assets in the energy industry, when transformers fail prematurely, damages can far exceed the cost of a replacement, and additional expenses may include the loss of production time and regulatory fines. A holistic monitoring approach integrates dissolved gas analysis, partial discharge, bushing monitoring, through fault currents and transformer analytics into a single system.
Dissolved gas analysis (DGA) initially developed for the monitoring of transformers was recently introduced for in-service diagnostics of power cables. Criteria successfully developed for transformers are not readily applicable to cables because of significant differences in the design and operating characteristics of both systems.
The diagnostic of a given cable circuit is based on the voltage rating, the individual gas concentration levels, the key gas ratios, the gas formation trends, the years in service, and the load. A new graphical representation of the IEC 599 method for the interpretation of gas ratios was developed in view of its application to power cable diagnostics. This new method, also applicable to transformers, solves most of the undetermined diagnostics given by the IEC method. The whole DGA diagnostic procedure logic is coded in an expert system shell automating the final diagnostic on the condition of the cable insulation.
Delegates attending the Dissolved Gas Analysis training course will develop the following competencies:
- Understand the importance of oiled filled power transformers
- Awareness of the characteristics of mineral oil in transformers
- Comprehend dissolved gas analysis for transformer
- Exposed to the construction of oil filled cables
- Determine dissolve gas analysis for the oil filled cables
TRAINING OBJECTIVES
EuroMaTech’s Importance of Dissolved Gas Analysis training course aims to assist delegates to achieve the following objectives:
- Define the roles and components of a power transformer
- Understand the different types of power transformer
- To appreciate the merits transformer oil functionalities
- Identify the components the oil filled components in the transformer
- Understand the functionalities and purpose of dissolve gas analysis
- Competence to identify the oil filled cables
- Be able to perform the dissolve gas analysis for oil filled cables
- To explore the online dissolved gas analysis merits and significance
WHO SHOULD ATTEND?
The technicians and maintenance staff will be able to perform correct maintenance procedures and troubleshooting of the UPS and battery systems. This EuroMaTech Training course is suitable to a wide range of professionals but will greatly benefit:
- Electrical Engineers
- Maintenance Technicians
- Management Professionals
- Project Engineers
TRAINING METHODOLOGY
The goals of each participant are discussed to ensure their needs are fulfilled, as far as possible. Questions are encouraged throughout, particularly at the daily wrap up sessions. This provides opportunities for participants to discuss specific issues and, if possible, find appropriate solutions. Case studies are employed to highlight particular points and appropriate video materials used to illustrate particular conditions.
TRAINING SUMMARY
This EuroMaTech training course on Dissolved Gas Analysis will expose the various topologies to the delegates. Upon completion of the course delegates will improve the maintenance strategies of their existing oil filled equipment, hence will optimize the operations of the transformers and oil filled cables.
