About Grant Transformers

A rich and long history of Australian ingenuity and engineering is what is offered by Grant Transformers.

Ron Grant founded Grant Electrical Industries Pty Ltd in 1931 originally, due to the depression of the era, the primary business at the time was that of an electrical contractor, how it evolved over the years was quite impressive. One of Ron’s sayings, one which is adopted still today and which resonates with the current team at Grant TransformersWe’re constantly looking for products that the fellow down the road hasn’t got the ability to make… or think out or develop”

The initial work involved all types of electrical work including transformers.

With rapid growth during the 50’s and 60’s the company comprised the following divisions: –

  • Grant Electrical Switchboards
  • Grant Electrical Contractors
  • Grant Elevators (Elevator Sales)
  • Grant Transformers
  • Grant Bosch tools

The company employed over 80 employees in the 1980’s.

In 1992 the business was broken into:

  • Grant Transformers
  • Elevator Sales

Grant Transformers continued to grow and provide a range of all types of dry and epoxy transformers for industrial needs as well as specially designed DC systems. Over the years Grant Transformers developed a high level of technical and manufacturing expertise. A key part of this expertise was to understand how customers were intending to use the transformer and translate this to technical requirements to enable a reliable product to be manufactured. In this way Grant Transformers developed skills in being able to provide the customer the exact solution they required.

Grant Transformers provides solutions to electrical problems involving transformers or chokes with over a combined 75 years of experience still being used as the highest level of technical transformer advice.

The products produced by Grant Transformers are manufactured utilizing superior quality materials. Standard products employ Class “H”, winding wires and Class “H”, Nomex insulation and moulded coil Bobbins where used, are manufactured from Class “F”, Glass filled flame retarded Nylon. Minimum Grade M3 and M4 Low Loss silicon steel is used in core manufacture. In other cases application specific core materials are utilised as required. IT based design procedures are employed, ensuring that customer product requirements or specifications are fully met prior to commencing manufacture. This process also permits the designer to optimise important product features. The company adopts strict quality management protocol according to ISO 9001 and industry good trades practice.

Grant provide details of the variety of standard type ferro-magnetic products which we manufacture or are able to supply.

Over the years the Grant Transformers changed hands and Greg Lynch purchased Grant Transformers operating it for a number of years successfully, focused on industrial and switchboard industries. Greg Lynch had been an apprentice with old man Grant from the early days and this was an inevitable change of hands as the Grant family divested from these businesses. As Greg got into his later years, Rohan Borrell based out of NSW who was also involved in a few acquisitions of transformer companies made an offer to take Grant Transformers on and operate it as a small business with a hand few loyal employees. This proceeded along for a few years supporting age old and very loyal customers.

In January 2017 Marco da Silva joined Grant Transformers as CEO, having immigrated from South Africa where he spent time as General Manager and later Managing Director of Ferro Resonant Technologies (FerroTech). Marco da Silva had been involved in the design and manufacture of Ferro Resonant transformers which was a key component of UPS’s (Uninterruptable Power Supplies) in the early 80’s and 90’s, along with the manufacture of other specialised transformers such as buck boost systems, isolation transformers, distribution transformers and voltage regulators/ power conditioners and UPS battery back up systems. With a track record spanning over 15 years in this industry supplying major blue chip companies and State entities in Africa and Europe, he found Grant Transformers an interesting opportunity to nurture and grow.

Today Grant Transformers employs over 18 employees with on going employment occurring often to increase its capability and support structures. Grant Transformers still proudly manufactures in Perth, Malaga and has setup to industrial contract manufacturing plants in Europe and the Far East to strictly manufacture to Grant Transformers specific needs. All products are finished in the Perth plant before supply to their customers. This has allowed Grant Transformers to supply from small ferrite PCB transformers, up to large Power Transformers rating to 50MVA and 133kV. Its scope covers both oil cooled ONAN and KNAN as well as VPI and Cast Resin Type Transformers. Fully integrated transformer kiosks with oil bunding or special accessories are all part of the turn-key supply capability.

Marco da Silva is also the Founder and Managing Director of Antipodes Power Solutions, a specialised Perth and Johannesburg based technology company involved in low voltage and high voltage PFC, Statcoms (Reactive Generators), Small Scale and Large Scale Solar Renewable solutions including general lithium ion battery back up to laboratory spec high end Graphene Hybrid Battery systems. Inverters and Rectifiers all fit part of these total delivered solutions.
