Grounding issues create many of today’s Power Quality problems.
system testing is as important as any other maintenance procedure. NRG,
Inc. has the capability of testing, troubleshooting and designing grounding
systems. This ranges from internal facility studies to ground grid
The Following are Typical
Grounding Measurements that NRG Can Perform:
Quality Grounding Problems: A major part of power quality
problems are associated with improper grounding techniques. NRG
performs site studies in which the grounding practices of panels and
transformers are checked. The improper bonding of panels or
equipment can cause serious power quality problems, which can be
solved with minor electrical revisions.
Electrode Resistance: Ground rods have several purposes.
They are used to discharge lightning strikes, protect personnel from
faults in the electrical power system, and for a reference potential
for instrument references and safety. It is also essential to
meet NEC, OSHA and other electrical safety standards. NRG can
perform resistance testing of ground electrodes to assure the levels
are within appropriate standards.
Grid Design / Soil Resistivity: NRG can perform soil
resistivity tests, which are essential when designing a grounding
grid. This test will also determine the best location for
driving ground rods, as soil resistivity is the key factor in
determining what the resistance of the ground rod(s) will be.
