For installations in harsh or polluted environments, our cast coil transformers offer high-performance, low-maintenance costs, and protection from short circuits, momentary overloads, impulse voltages, and temperature fluctuations.
PQI has been on the leading edge of harmonic mitigation solutions longer than any other manufacturer in the industry. Our harmonic mitigating transformers are manufactured to the highest quality standards in an ISO 9001 facility, and our product designs have been proven highly effective in real-world scenarios. PQI harmonic mitigating transformers meet or exceed their published efficiencies under the nonlinear load conditions for which they’re designed. For these reasons, many engineers insist upon PQI for the most effective harmonic mitigation solutions.
While we primarily supply transformers less than 600V, our ultra-efficient and harmonic mitigating products are also available at medium voltages.
Our Type EY e-Rated® transformers are an easy choice for building owners looking for energy-efficient solutions with exceptional performance, even in lightly loaded settings such as schools and commercial buildings. Because distribution transformer loading is typically in a range between 9% & 17% of their full load rating, we’ve designed our e-Rated® transformers with extremely low Excitation (no-load) Losses. This is achieved with advanced full and step-lap, miter-cut core designs using high quality grain-oriented silicon steel.
