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.
Standard Products
| PQI Product | Description | Benefits within Hotels & Casinos |
| EY (e-Rated®) | Ultra-efficient transformer | – Low first cost – Ultra-low excitation (core) losses reduce power costs |
| DV Distribution TransFilterTM | Harmonic mitigating transformer | – Reduces power costs – Reduces penalty losses due to harmonic currents – Reduces transformer heating and A/C loading – Reduces THDv to less than 5% at nonlinear loads or motor drives – Reduces losses in the loads, thereby reducing A/C requirements – Improves switch-mode power supply’s ‘ride-through’ capability – Balances primary phase currents – Assures system compatibility with sensitive electronic loads – Capable of developing 12-, 18-, 24-, and 36-pulse primary systems |
