JILS - Investigating the partial discharge testing of 3 ø transformers


This event has been rescheduled till Wednesday 22 February 2023.

Learn how to measure partial discharge in poxy cast three-phase transformers up to a voltage rating of 36kV ø – ø voltage.

The testing of 3PH epoxy cast power transformer for partial discharge is more a “skilled art” than an absolute science. It takes much detailed experience to understand the complete subject of partial discharge testing. The understanding of the circuit, the power supply, the filtering plus the earthing are fundamental concepts to understand before you can attempt to study and understand the measuring circuitry and the equipment testing process.

Michael Larkin of Tortech Transformer


A Sir William Tyree scholarship holder in 1973 at the UNSW School of Electrical Engineering, Michael also holds a financial degree from the Kuring-Gai College of Advanced Education. Michael’s background in electrical transformers dates back to 1976. He designed the first 500kV post type outdoor CT while working at Tyree and has gained professional experienced at Tyree Electrical, Westinghouse Tyree and Ferguson Transformers. In 1987, Michael set up Tortech, a company originally specialising in toroidal transformers before branching out to include three-phase transformers and other products.Michael
