What ZERO GROUND System Solution does

  • Significantly Reduces Unplanned Downtime*, Reduces Maintenance Costs Due to Issues Associated with ASD’s / Motor Installations
  • Reduces High Frequency Ground Currents to Zero
  • Extends Motor Life
  • Directs Fault Currents Away From Hazardous Locations to be safely dealt with.

*Unplanned Downtime – Cost of Labor, Materials, Lost Equipment (Repair or Replacement) and Lost Product

The ZERO GROUND System Solution provides unsurpassed performance in reducing EMI/RFI by PWM or high frequency power supplies. The ZERO GROUND System Solution has been engineered and designed as a complete wiring system to be installed between a source and an Adjustable Speed Drive controller and an electric motor or in any wiring scheme where there is the possibility of high frequency voltages tending to stray. ZERO GROUND uses no filters in reducing ground currents to zero.

In replacing a standard wiring system for a VFD cell in one of our Beta Sites, ZERO GROUND reduced 1,538 milliamps to Zero. We define Zero, as five places to the right of the decimal point (please see graphs below):


("ELECTRICAL NOISE" measured before ZERO GROUND System Solution; note: before graph vertical divisions are 500 mA)


("ELECTRICAL NOISE" measured after ZERO GROUND System Solution; note: "after" graph vertical divisions are MAGNIFIED 10x to 50 mA)

When the ZERO GROUND System Solution is installed correctly, this design addresses the issues related with large switching power supplies in BJT, SCR, GTO, IGCT and IGBT technology(s), in conjunction with motors, motor cables, power supply cables, as well as PE ground grids, and rapid rise pulse phenomenon. Our patented system delivers the following:

1) Contains and Mitigates Stray Capacitance

2) Contains and Mitigates Capacitively Coupled Energy

3) Contains and Mitigates Inductively Coupled Energy

4) Contains and Mitigates Common Mode Voltage

5) Minimize Corona Inception Voltage (CIV) in motor cable leads

6) Eliminate motor frame voltage to ground

7) Minimizes all crosstalk between adjacent cables

8) Eliminates stray voltage (CMV) and thereby inhibiting stray currents (CMC) from

flowing in PE equipment grounding circuit(s)

9) A possibility exists that the reduced impedance of our ZERO GROUND

system, could reduce the sum effect of reflected waves.
