Mirus Neutral Current Eliminator (NCE)

MIRUS Neutral Current Eliminator (NCE)

A 3-phase, low zero sequence impedance autotransformer, which when connected near to and in parallel with the harmonic generating non-linear loads (usually connected at the distribution panel), provides an alternate path for 3rd, 9th, & 15th current harmonics (triplens) which the loads create. Patented Field Adjustable Impedance (FAI) feature allows for adjustment of NCE™ zero sequence impedance to field conditions.

Reduces neutral current and neutral-to-ground voltage as well as both current and voltage triplen harmonic distortion.

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
