Welcome to the ZERO GROUND System
Solution
Welcome to ZERO-GROUND.com...
Home of the World's Most Advanced Patented Wiring System Solution for
Variable Frequency Drives (VFD’s), Adjustable Speed Drives (ASD’s),
Uninterruptible Power Supplies (UPS’s) and Computer Systems.
The conventional
wisdom and standard practice of grounding electrical circuits to “physical
earth” for SAFETY (in accordance with the NEC), was initiated
over 100 years ago. Over the past few decades, technological developments
including Variable Frequency Drives and power devices utilizing IGBT’s
and other fast switching power devices have been introduced to the market.
These technological developments (VFD’s, UPS’s, SERVOS and
Computer Controlled systems) typically generate high frequency ground
currents, which when grounded to “physical earth” can cause
issues affecting other sensitive electrical/electronic equipment. as
well as shocks, sparks and arcing. High frequency ground currents can
and do cause motor bearings “currents” which leads motor
bearings to fail prematurely (causing premature motor failure).
These high frequency
ground currents cannot be eliminated; however, they can be contained,
controlled and re-directed, which is exactly what is protected in our
ZERO GROUND System Solution patented components and installation method.
The ZERO GROUND System Solution provides a more effective ground which:
REDUCES
HIGH FREQUENCY GROUND CURRENTS TO ZERO
REDUCES
MOTOR BEARING CURRENTS
EXTENDS
MOTOR LIFE
INCREASES
SYSTEM Mean-Time-Between-Failure (MTBF)
REDUCES
UNPLANNED DOWNTIME
DIRECTS
FAULT CURRENTS AWAY FROM HAZARDOUS LOCATIONS
The ZERO GROUND
System Solution new paradigm now allows grounding technology to catch
up to equipment technology.
In replacing a standard
wiring system for a VFD cell in one of our Beta Sites, ZERO GROUND System
Solution 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)
