Hotels and Casinos

With high concentrations of nonlinear loads, such as gaming machines, operating 24 hours per day, power quality is an extremely important consideration in casino design and operations. Energy losses, equipment failure, and data corruption, which can cause high gaming machine payouts, are some of the common outcomes of high current and voltage distortion caused by these nonlinear loads. We generally recommend proper application of our harmonic mitigating Distribution TransFilters™ to solve these issues. In addition, because the nonlinear loads in casinos are typically located a significant distance from the distribution transformers, our Type Z zero-sequence harmonic filters are critical for reducing voltage distortion at these loads. PQI’s reputation in the casino industry is unparalleled with hundreds of our products in casinos around the world.
