Why the ZERO GROUND System Solution
Was Developed
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
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.
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 MTBF*
REDUCES
UNPLANNED DOWNTIME
ZERO GROUND's new
paradigm now allows grounding technology to catch up to equipment technology.

MTBF |
Mean time between
failures.
An average time between machinery breakdowns. If the MTBF decreases,
root cause analysis must be carried out to bring the MTBF # to a
high, meaning long times between failures. PM, TQM, JIT, better
controls and the ZERO GROUND “System Solution” are all
tools to make MTBF higher. |
