  • Inspections and witness testing during manufacture
  • Condition assessment whilst the transformer is in service
  • Expert advice in transformer operational matters
  • Condition assessment on occasion of mid-life refurbishment
  • Failure investigation following in-service failures

Several recent investigations into the reason for in-service failures of transformers included investigation into the failure of two generator transformers in New Zealand, an investigation into the failure of a 90 MVA auto-transformer in Kuala Lumpur, investigation into the failure of two power transformers in Queensland and investigative contributions with respect to in-service failures over a 10-year period in the NSW high voltage grid.


Walter Wasinger regularly presents in transformer technology seminars in Australia, giving papers on the following subjects:

Short Circuit Forces in Transformers, Transformer Design, Reactor Design and Testing,
How to balance Risk and Cost, Design Reviews, Tap-changers, Power Transformer Operation,
