About this course
Covers the routine and corrective maintenance that keeps distribution and power transformers in service. Delegates study inspection routines, oil sampling and treatment, breathers and silica gel, bushings, tap changers, cooling systems, gaskets and leaks, Buchholz and temperature protection, and how to use test and oil results to plan maintenance by condition rather than by calendar alone.
Why this course
Transformer failures often follow neglected basics such as wet oil, saturated breathers, leaking gaskets and worn tap changer contacts. Replacing a failed unit costs far more than routine care, and lead times can be long. Good maintenance extends service life, reduces failures and delays costly replacements.
What delegates will be able to do
By the end of the course, delegates will be able to
- Carry out a routine transformer inspection using a standard checklist
- Take oil samples correctly and interpret basic oil test results
- Maintain breathers, bushings, gaskets and cooling systems
- Inspect and service on-load and off-load tap changers
- Plan condition-based maintenance using inspection, oil and test data
Who should attend
Maintenance technicians, electricians, substation staff and maintenance planners at utilities, municipalities, mines and industrial sites with distribution or power transformers. Delegates should know basic transformer principles and substation safety rules. Those wanting detailed electrical diagnostics should also consider Transformer Testing.
How it is delivered
Facilitator-led sessions with practical demonstrations on transformers and tap changers, oil sampling exercises and maintenance planning work using sample records. It is available as a public course or in-house at your premises. The practical work needs equipment and supervision, so it is not offered online. Duration and dates are confirmed in your quote, and in-house groups can have the examples and exercises fitted to their organisation.
