Experience – Petro-Chemical Industry
- Design review and Expert witness of failure investigation of several oil type transformers rating 16 MVA – 30 MVA for adjustable speed drive applications.
- Conducted complex investigations into utility power failure resulting in shutdown of two major oil refineries.
- Conducted motor starting analysis and computer modelling for 13.8 kV, 25000 HP synchronous motor under normal and abnormal utility conditions for a large chemical plant in Ontario. Prepared a report with recommendations.
- Completed a complex electrical failure analysis and field measurements of three slow speed 17500 HP, 13.8 KV brushless Synchronous motors driving reciprocating compressors. All failures were rotor related that made predicting the failures very challenging. The first motor suffered a cracked shaft that had to be replaced. The second experienced arcing amortisseur bars and the third shorted field winding.
