Applied Energy Logo  Phaseback

PhasebackApplied Energy, LLC has designed Phaseback to operate at the beginning of voltage change in the manner of an inductive circuit.  Reacting at millivolt changes in voltage Phaseback prevents the degradation that occurs with the current flow allowed before present technology TVSS products clamp and redirect that current. Phaseback works like a voltage pull down circuit to high phase voltages and a pull up circuit to low phase voltage while filtering noise. Phaseback continues to monitor phase voltages, filter noise and balances phase voltages as it is always online even during a direct short to ground.  Phaseback functions as a voltage stabilizer, surge suppressor and harmonic filter. 

Phaseback has no relays, contactors, or trip units that could fail and disable the system. Its MTBF (mean time before failure) is designed to exceed 35 years.  The original design has been a success with over 10 years of development and continuous testing in various industrial applications.  Phaseback has performed well in both grounded WYE and ungrounded DELTA power systems, balancing phase voltages in ungrounded DELTA systems to prevent motor winding failure due to high voltage stress ultimately reducing electric motor winding failures by about 98%.  Furthermore, the system has demonstrated that it cleans up the high frequency noise and voltage spikes associated with arcing ground faults in hundreds of computerized CNC machines allowing productive operation as opposed to frequent rebooting and maintenance.
