First, few if any products will remain in service as long as the transformer you select. It is not uncommon to find transformers still in service after 40 or 50 years.

The second reality is, the loads that we place on our systems today are computers, laser printers, video monitors, electronic ballasts, variable speed drives and ups. Loads that are connected phase to neutral ( equipment typically plugged into a wall receptacle) produce an abundance of 3rd, 5th and 7th harmonic currents. Phase to phase and three phase loads ( variable speed drives for example ) that are 6 pulse produce mostly 5th and 7th harmonics.

Thormag transformers are designed specifically to cope with and harness those load-related 3rd, 5th, 7th, 9th and other 'harmonics'; while operating at ultra-high efficiency, all the time. In comparison, the traditional approach tries to survive the same harmonics by compensating and relying on over-capacity. This over capacity drives the cost up even more.

Energy conscious building owners, landlords and tenants are discovering how improved power quality means improved electrical performance, energy and other cost-related savings. This brings 'added value' to the building itself.

Tough. Durable. Efficient. Thormag Power products are designed to perform both smarter and longer than anyone else's. That's why Thormag Power has the longest warranty in the industry.

In general our transformers are:

Copper wound dry-type distribution transformers

Insulated with the highest quality systems that are UL recognized and CSA certified

Tested extensively under linear and non-linear (if required) loads  to ensure conformance to the nameplate rating and to the NEMA TP1 standard
