Valuation of transformer losses: Food for thought

By Debra Vogler, senior technical editor

March 18, 2011 -- Steve Winden, sales manager at Virginia Transformer Corporation, makes a case for the valuation of transformer losses in a podcast interview at the Renewable Energy World/Photovoltaics World Conference & Expo (3/8-3/10/11, Tampa, FL).

"Transformers are designed on the value that utilities put on their losses," explained Winden. For example, some utilities place a value of as much as $7000-15,000/kW on their no-load losses, he noted. "Yet, when you get out into the industrial world, they don't understand that losses have value."

Buying a more efficient transformer costs more on the front end, said Winden, but the long-term goal is a lower-loss transformer that uses less electricity. "The reality is, it's a savings for customers and, long term, for the energy system."
