Type PY harmonic mitigating Power TransFilters™ exceed all existing and pending energy efficiency requirements under nonlinear loading.
Type PY transformers’ ultra-low Excitation (no-load) Losses provide high efficiency during periods of light-loading (<15% FL). This benefit is achieved by using higher quality, grain-oriented silicon core steel and full and step-lap miter-cut cores with reduced laminations per group.
Unlike Excitation Losses, which are constant from no-load to full-load, Impedance (load) Losses become significant at approximately 15% FL. Excitation and Impedance Losses are approximately equal at 50% FL under linear loading. Type PY transformers exceed the efficiency requirements of DOE 2016 under linear loading. Optional e-RatedÒ units exceed these efficiency requirements under moderate nonlinear loading (≤K-9). Type PY transformers’ published efficiencies can be matched to anticipated or measured average loading above 50% FL, when required.

Type PV transformers’ published efficiencies can be matched to anticipated or measured average loading above 50% FL, when required.
Type PV transformers cancel positive- and negative-sequence harmonic currents at their common primary bus or within their multi-output secondary windings. They are available in a number of standard primary-to-secondary phase-shifts so that they may be used to create twelve-, eighteen- or twenty-four-pulse systems. In addition, Type PV transformer’s secondary windings are configured to cause the cancellation of all load-generated third-order zero-sequence flux in the core’s magnetic circuit.
