About ZERO GROUND System Solution
Since 1998, the
ZERO GROUND System Solution has been used to safely wire all input and
output connections included with large switching power supplies. ZERO
GROUND addresses issues associated with Adjustable Speed Drives in BJT,
SCR, GTO, IGCT and IGBT technology(s), in conjunction with motors, motor
cables, as well as PE ground grids, and rapid rise pulse phenomenon.
ZERO GROUND has invested
$3.5 million in Research, Development, Technical and Product Testing.
Our experienced staff of engineers has over 175 years of industry experience
with drives, motors, magnet wire, cable and conduit.
ZERO GROUND System
Solution meets all requirements of NEC 336 Power and Control Cable Type
TC, NEC 350 Liquid Tight Flexible Metal Conduit Type LFMC and NEC 250
grounding. Testing was completed (2002) at Toshiba International Corporations’
Government Certified NVLAP Lab in Houston, TX. In addition, the ZERO
GROUND System Solution has been operating successfully for over three
years at various Beta Sites. The NVLAP Lab test data, coupled with the
Beta Site information, validated claims for our US and International
Patents. ZERO GROUND cable and conduit are now UL (Underwriters Laboratories)
listed materials. In addition, ZERO GROUND System Solution is now rated
for Class I Division II Hazardous Applications. ZERO GROUND has diligently
worked with the United States Mining Safety and Health Administration
(MSHA), who have reviewed our data and visited our Beta Sites to verify
claims. MSHA continues to work with us in utilizing the ZERO GROUND
System Solution with equipment meeting MSHA safety requirements for
the mines.
All ZERO GROUND
System Solution cables and conduits are UL listed materials.
All ZERO GROUND
System Solution cables are rated for 2000V AC RMS. The maximum horsepower
(and voltage) this can be used for is: 1 - 500 HP @ 480 V, 3 phase (0
- 50 KHz) and 1 - 250 HP @ 240 V, 3 phase (0 - 50 KHz). ZERO GROUND
is being successfully used in the field, with motors as follows:
5 HP @ 240 V, 3 Phase
20 HP @ 480 V, 3 Phase
50 HP @ 480 V, 3 Phase
125 HP @ 480 V, 3 Phase
All of these field applications
are running (ASD’s) drives.
ZERO GROUND System
Solution offers Safety & Reliability by reducing High Frequency
Ground Currents to Zero and by directing fault currents away from hazardous
locations to be safely dealt with. In addition ZERO GROUND significantly
reduces unplanned downtime*, due to issues associated with ASD’s
/ motor installations.
