SmartGATE™: A Dynamic Power Quality Correction Device for Commercial Buildings
The SmartGATE analyzes and corrects the power coming into the building in real time. The system is installed in series with the electrical service, providing a voltage adjustment up to +/- 8%. The patented topology of the system allows for eﬃciency greater than 99.5% across the operating range.
The core of the system is comprised of 2 transformers, an active bridge, and a control system. The control system analyzes the individual voltage waveform and computes the ideal correction. The ﬁrst transformer extracts up to 10% of the system power while the active bridge constructs the required waveform correction as determined by the control system. The second transformer is used to inject the corrected waveform back into the building connection. SmartGATE is the only complete power quality management solution sized and priced for commercial building applications.
Full voltage regulation ±8%, Phase Balancing, Voltage Buck up to – 8%, Voltage Boost up to +8%, Sag mitigation, Swell mitigation, Surge Suppression and Power Factor Correction
Each SmartGATE is conﬁgured to each power feed to improve power quality and save energy.
Full Voltage Regulation:
Buck and Boost voltage regulation ±8% of supply, holding voltage to a near constant level on a cycle-by-cycle basis. Reduces energy consumption while increasing equipment reliability and life-expectancy.
±8% phase-by-phase voltage buck and boost regulation – regulating each phase independently to produce balanced three phase power. Reducing operating temperature of three phase loads, increasing eﬃciency and extending equipment life-expectancy.
+8% voltage boost, responding to a voltage sag and reduction within 1 cycle. Mitigates and protects equipment from malfunction and failure during voltage sags – extending voltage ride through envelope.
Automatic voltage reduction in discreet increments, including a 0% bypass step, to produce a controlled voltage reduction to reduce a building’s energy usage.
