Power Transmission & Distribution Technical Training > Advanced Level – Assessing and Monitoring the Condition of Power Transformers by Oil Analysis – Virtual Instructor Led Training (VILT)

About this Virtual Instructor Led Training (VILT)

The objective of this 4-half-day Virtual Instructor Led Training (VILT) course is to equip participants with the required knowledge so that they can define and implement an effective oil analysis programme, monitor the condition of transformers and understand oil analysis reports as part of their maintenance strategy.

This VILT course is delivered in partnership with ENGIE Laborelec.

Participants will be able to go through the following areas during the VILT course:

Condition monitoring of power transformers through oil analyses:

  • Transformer Health Index, Transformer Fleet Condition Assessment, Risk Matrix
  • Best practices
  • Which oil analyses/how frequent
  • DGA: focus on partial discharges, sparking, stray gassing, catalytic effects / interpretation systems.
  • Interpretation of results
  • Why and when to perform electrical measurements?
  • International standards: IEEE, IEC, Duval, ASTM, etc
  • Maintenance guidelines
  • Trending and reporting
  • Sampling techniques

Use of online monitoring for DGA/water: implementation and real-case advantages etc:

  • New developments: importance of methanol as ageing marker, temperature correction of ageing markers, stray gassing of oils in service etc
  • REX, case studies and real-case exercises concerning power transformers within generation and high-voltage grids
  • Discussion of reports on power transformers
  • Use of unused insulating transformer oils
  • Market trends in the use of inhibited and uninhibited oils
  • Differences, advantages and drawbacks of uninhibited compared with inhibited oils
  • Importance of additives, oxidation stability tests, stray gassing, etc

The VILT course is intended for a wide audience, including professionals who are maintenance staff, electrical engineers and asset managers responsible for transformers. Typical industries are powerplants, high voltage grids or large industrial sites.

The VILT course will be delivered online in 4 half-day sessions comprising 4 hours per day, with 2 x 10 minutes break per day, including time for lectures, discussion, quizzes and short classroom exercises.

Course Duration: 4 half-day sessions, 4 hours per session (16 hours in total).

This VILT course is delivered in partnership with ENGIE Laborelec.
