PCT_SolarPacific Crest Transformers announces that it offers the SPSU photovoltaic (PV) solar converter step-up transformer, ideal for connecting solar farms to the electricity grid at large-scale solar power installations. Reliable and efficient, PCT’s step-up transformer is an engineered solution with the design flexibility needed for the solar market. PCT’s West Coast U.S. location ensures speed of delivery.

The SPSU is uniquely designed for the additional loading associated with non sinusoidal harmonic frequencies often found in inverter-driven transformers. An innovative system of multiple windings reduces transformer costs and minimizes transformer footprint by combining the step-up function to fewer transformers than other systems.

Designed and constructed to meet and exceed earthquake standards, the SPSU is rated for installation in the highest earthquake rating zones. In addition, PCT’s SPSU PV solar converter step-up transformer incorporates a variety of fluids, including less flammable fluids required for enclosed applications.
The SPSU model features circular windings that spread the radial forces evenly over their circumference and have cooling ducts throughout the coils, eliminating hot spots that lead to premature breakdown and ultimately to transformer failure. Coil end blocking with heavy duty 3 gauge steel bracing and proprietary pressure plates contains the axial forces exerted during a fault condition. These forces can cause telescoping of the coils, shortening transformer life.

The Model SPSU features an innovative design that includes round coils, a cruciform, mitered core with heavy-duty clamping and a proprietary pressure plate design, as well as a premium no-load tap changer.

“New energy applications require new technologies,” said Tom Steeber, Pacific Crest Transformer’s vice president of marketing and sales. “The SPSU step-up transformer is especially designed to meet the solar industry’s need for reliable service in remote locations, and offers superb fault survivability.”
