Presentation by Michael Larkin - Managing Director of Tortech Pty Ltd and Tortech Lighting Pty Ltd

The design of 3 phase transformers has been standard for some years. However, with the introduction of new magnetic material and the ever increasing demand for power efficiency, we are constantly developing new designs to meet these efficiency requirements.

Recently our team at Tortech has researched IP56 3 phase transformer design for the NSW State Railway using special stainless steel enclosures. We have successfully overcome the problem of high temperature failures by using air cooled transformers. The solution is in using thermodynamic principles incorporated in with the Electrical transformer design.

In addition, our Solar Isolation Transformer Design incorporates the perfect solution for minimising the core losses, and thereby improves the efficiency and temperature characteristics of the enclosed transformer. This has enabled the Solar Inverters to operate more efficiently and provide substantial cost savings to the customer.

The talk will review some of Tortech’s R & D research areas including:

1) Calculation of temperature rise of enclosed 3 phase aircooled transformers

2) Use of different core steel characteristics based onapplication

3) Design of IP56 stainless steel enclosures for 3 phasetransformers

4) The solution for the problem of “in rush” current forrailway applications

5) The use of aluminium windings in air cooledtransformers

This talk will review the innovation in winding techniques and cooling calculations that have been developed recently for the major industry applications in Mining, Railway, Transport and Solar Power.

The talk will be stimulating and interesting to both the experienced engineers and those new to the workplace.

SPEAKER BIOGRAPHY

Michael Larkin

Michael Larkin is the Managing Director of two Sydney-based businesses, one is transformers and the other is a lighting business, Tortech Pty Ltd and Tortech Lighting Pty Ltd.

As a UNSW Electrical Engineer Honours Graduate he was sponsored by Sir William Tyree and began his career at Tyree Westinghouse, Liverpool in 1976. During this period he gained valuable “hands-on” experience in the design of 33KV, 66KV 3 phase oil-filled transformers up to 20MVA, and the computer design of large power transformers. He also gained expertise in the design of high voltage current transformers, magnetic voltage transformers and capacitor voltage transformers for SECV and ECNSW supply authorities.

Later he expanded his skills into Sales and Marketing to become Product Manager for Ferguson Transformers. In this capacity, he liaised with customers and helped solve their technical problems. He designed High Intensity Discharge control equipment for various applications including the illustrious WACCA Cricket Ground in Perth. He also designed single and three phase dry type transformers and battery chargers.

In 1987 he established his own toroidal transformer business called Tortech Pty Ltd, which provides design, approval and manufacture (local and overseas) of transformers ranging from toroidal transformer s and chokes, three phases dry type transformers up to 500 KVA and most types of transformers required in a variety of applications from government departments such as the NSW/QLD Railways, Defence Department, Air force, Navy, Satellites, to overseas embassies , medical equipment, mining power supplies and general transformers and power supplies for farms, commercial and home use.

As a Chartered Professional Engineer with the IEE, Michael is proud to be able to give back to the new

generation of upcoming engineers. At Tortech Pty Ltd he mentors Engineering Graduates and

provides training in transformers and LED lighting. He is an enthusiastic presenter and a “powerhouse

“of knowledge.
