Hammond Power Solutions (HPS), originally known as O.S. Hammond and Son was established in 1917 in Guelph, Ontario by Oliver Hammond to build various tools for the foundry industry. O.S. Hammond and Son began making tube radio sets, battery chargers and other related products between 1919 and 1927.  Their philosophy for quality and success was simple:  “Build the product like you were going to use it yourself.” Oliver passed away in 1925 and his four eldest sons took over the business. It was in 1927 that the company changed their name to Hammond Manufacturing.  Along with the name change came other transformations. At this time, the Hammond family changed their focus from radios to transformers and filter chokes for broadcast transmitters and AC radio sets.

With the start of World War II in 1939, Hammond started to build specialized transformers and reactors for military communication and radar equipment. Almost overnight the Company grew from under 50 employees to over 300 to satisfy the critical surge in demand for transformers.

In 2001, Hammond Manufacturing officially became two companies.  Rob Hammond headed Hammond Manufacturing, which manufactures electrical enclosures, electronic packaging, power bars, and electronic transformers. Bill Hammond renamed his transformer division Hammond Power Solutions, which manufactures custom and catalog transformers and related magnetics. This reorganization has enabled both companies to pursue their strategic goals independently, providing an orderly succession to the next generation of the Hammond family and an opportunity to create increased enterprise and shareholder value. Behind the Hammond name is a rich history spanning over 90 years.

“At the end of the day, the most evident way to understand what our values mean is to see them at work all around us. To see people be more open and honest with each other, to gather facts to make better decisions, to be more open to change and looking for better ways, to treat others the way we want to be treated. These are the ways that we will see our core values at work throughout HPS.”

Hammond Power Solutions is the largest manufacturer of dry-type transformers in North America. We engineer and manufacture a wider range of custom transformers that are exported globally in electrical equipment and systems. We support solid industries such as oil and gas, mining, steel, waste and water treatment, and wind power-generation.

Our stability and integrity as a supplier are paramount in an industry where demands must be resolved quickly and effectively. HPS has grown to become the largest dry-type transformer manufacturer in North America.

HPS is well positioned for growth and has several long term and short term plans to continue on this path of success. As North America’s leader in the dry-type transformer industry, we have every intention of staying there and getting stronger.
