MIRUS Combined Neutral Current Eliminator (CNCE)A patented phase shifting autotransformer with a low zero sequence impedance at its output. When connected in series on a 3-phase, 4-wire service to non-linear loads, it provides an alternate path for the triplen harmonics. The CNCE™ also phase shifts 5th and 7th current harmonics by 180º so that they cancel with 5th and 7th harmonics from other loads on the distribution system. Optional FAI feature allows for removal of triplens from the CNCE™ input side as well as secondary.Reduces neutral current, and neutral-to-ground voltage, as well as both current and voltage harmonic distortion at 3rd, 5th, 7th, & 9th harmonics.Features• Diverts the flow of harmonic currents away from neutral and upstream transformer• Reduces high neutral current and neutral-to-ground voltage• Eliminates the need for doable ampacity neutrals upstream• Reduces losses and lowers operating temperature in upstream distribution transformer• Substantially reduces primary winding circulating currents in distribution transformers• Reduces current distortion at UPS, generator or Utility service• Saves energy by reducing harmonic losses• Prevents voltage flat-topping caused by non-linear loads• Lowers voltage distortion to prevent premature equipment failure• Restores ride-through capability of computer equipment• Improves Power Factor• Integrated ammeter measures neutral current removed• Field adjustable impedance option offers improved application flexibility• Helps meet IEEE Standard 519 harmonic limits
