2-Days Training Course on Condition Monitoring of Power Transformers through Oil Analyses

The course at a glance

The purpose of this training is twofold:

Acquiring the knowledge needed to define and implement an adequate program of oil analyses to monitor the condition of transformers.
Understanding and interpreting oil analysis reports and implementing maintenance recommendations.

Maintenance staff, operators, asset managers, responsible for transformers, technical project managers

2 days

Condition monitoring through regular oil analyses: best practices for power transformers
Sampling practices
How does a transformer fail? Ageing of the paper/oil insulation system?
Adequate oil analyses programs (frequency, which analyses) in function of transformer type and condition
Interpretation of analyses results / relevant IEC/IEEE standards and maintenance guides
Appropriate maintenance actions in function of ageing (reconditioning, reclaiming, reinhibition, passivation, …)
How to read routine reports and how to make up interpretation and recommendations based on oil analyses results : case studies and exercises

The course also covers specific transformer oil-related ‘hot topics’:

Dissolved gasses and stray gassing
Online monitoring of water/%RH and dissolved gasses by Hydran or equivalent (accuracy of the readings, alarm settings, procedures what to do when alarms are exceeded)
Case studies showing added value of online monitoring
Specific case studies related to partial discharges
Ageing estimation of power transformers: importance of furans and methanol : context and how to implement adequately
Corrosive sulfur: context, actions, GDFSUEZ approach, context GLOW
Unused oils: trend versus inhibited oils
