About

ZERO GROUND engineers and manufactures specialty shielding and grounding solutions for government, defense and commercial applications.  

Zero Ground has two offerings:

1) ZERO GROUND HFES® - Patented components / method for High Frequency Extraction System (HFES). In switching power supply (ie: Variable Frequency Drive - VFD) applications, the high speed switching of the IGBT (Insulated Gate Bipolar Transistor) generates high frequency ground currents which affect motor life, sensitive devices and cause safety issues. These ground currents cannot be eliminated, although they can be contained, controlled and redirected, which is what HFES does. HFES is the ONLY proven and now patented method to reduce high frequency ground currents to zero in ideal conditions, and by more than 90% in typical conditions. HFES is used in all VFD / motor low voltage (1,000 V) applications from 10 HP - 500 HP. HFES has been verified by the US Dept. of Labor and endorsed by ABB, the largest drive manufacturer in the world. See website for published IEEE "white" paper. www.zero-ground.com

2) ZERO GROUND dBzSHIELD® - ZERO GROUND dBzSHIELD® shielded flexible liquidtight conduits are designed for wiring applications requiring shielding effectiveness from Electromagnetic and Radio Frequency Interference (EMI / RFI). dBzSHIELD Shielded Flexible Conduits have been designed for Modified Commercial Off The Shelf (COTS) applications, offering a lower cost and standard fittings alternative to high-end mil-spec shielded conduits, which typically require expensive custom fittings. Typically supplied to Government, Military and Defense contractors including Boeing, Northrop Grumman, DRS Technologies etc. See website for specifications. www.dBzSHIELD.com
