Commercial and Industrial
For commercial buildings, we recommend evaluating our ultra-efficient e-Rated® transformers. Also, because these facilities often support a high percentage of electronic loads (computers, phones, LED lighting, etc), we recommend evaluating our Distribution TransFilters™ to reduce flat-topping of the voltage waveform at the loads’ switch-mode power supplies and improve overall system efficiency.
For industrial facilities, harmonics from nonlinear loads, such as motors drives, electronic lighting ballasts, and rectifiers are a primary cause of equipment failures and energy losses. Harmonic mitigation is especially crucial for operations involving motors since harmonic currents lead to decreased motor efficiency, increased heating, and reduced motor life. We will work with you to develop a system-wide approach that may include proper application of our Distribution TransFilters™, to deliver high power quality with outcomes including:
- Improved system and load compatibility
- Improved overall system efficiency with reduced transformer, cable losses, and motor (and other load) losses
- Reduced equipment failures
- Improved production rates (production per kWh)
