Dairyland is the energy industry’s leading resource for solid-state products and solutions, providing exceptional technical support, customer service and product quality that have been trusted for over 30 years.

If you’ve seen Dairyland at industry tradeshows, or followed our technical newsletter, chances are you’ve seen some of our cows. Everyone seems to love our squishy bovines, but many ask “What’s up with the cows?"  Upon reflection, they then also ask "What's with the name Dairyland?"

Well, Dairyland was incorporated by Henry Tachick in 1983 to address a great need by power utilities for a solid-state approach to the bonding of utility-to-customer grounding systems under certain conditions. This problem caused stray voltage problems for utility customers, typically on dairy farms, which was a massive nuisance to the cows. The first Dairyland products were born, and our utility customers were pleased.  And so were the cows.

Dairyland has the privilege of being located in the state of Wisconsin, known as America’s Dairyland. Hence the Dairyland name and the reason for the cows.

A little more about Dairyland

While Dairyland still offers solutions for the original stray voltage problem, our main markets today are the cathodic protection industry (for pipelines, tanks, power utility structures, boats and more), lightning and fault protection schemes (rail, utility, etc), and custom products. Dairyland pioneered many modern protection approaches, applying solid-state technology to create isolation & grounding products that are now used worldwide. Dairyland trade names, such as the Polarization Cell Replacement or "PCR", and the Solid-State Decoupler (SSD) have become common to the corrosion prevention industry, are widely accepted, and have lead to industry adoption of Dairyland terms for these products, such as "decouplers."

Other core competencies include products for over-voltage protection, including the Over-Voltage Protector (OVP & OVP2), to improve upon limitations of existing industry "lightning arresters." Dairyland is also uniquely positioned to explore and offer custom devices that build on our knowledge of power protection and engineering. Where aspects of solid-state construction, electrical isolation, safety grounding, and over-voltage protection intersect, Dairyland has the expertise to offer novel designs and solutions.

Whether it is entering new markets, enhancing our products, or designing and manufacturing specialty devices, we are always excited about new opportunities to serve our industry. We will continue on the path that has been beneficial to our employees, our clients and the industry.
