Harmonics in an electrical current are one
indication of poor power quality. They cause
overheating in electrical components and can
damage sensitive equipment, impacting your processes and assets. Poor power
quality can result in:
l
Premature equipment failure
l
Equipment turning on or off unexpectedly
l
Erratic equipment performance
l
Unexpected energized metal—panels or
components carrying a charge that shouldn’t
be
l
resulting in a safety issue
l
Overheating of motors or other conducting
equipment
If you're experiencing such problems,
HVM technicians can help identify the
cause by monitoring your system for
harmonics, voltage dips and other
disturbances.
Features & Benefits
l
Identify power quality problems
l
Reduce nuisance trips
l
Extend equipment life
l
Improve system reliability
Scope
Harmonic analysis is typically conducted as
part of a power quality study to identify
the source of harmonics and develop a plan
for corrective action.
A harmonic analysis study can:
l
Identify harmonic problems
l
Reduce nuisance trips
l
Calculate load flow
l
Identify harmonic distortion problems
l
Identify & analyze telephone interference
problems
l
Identify parallel resonance conditions
Once a study is complete, a report will be
issued including:
l
Voltage & current harmonic distortions
l
RMS, ASUM, TIF, & I*T values
l
Bus impedances (magnitude & angle)
tabulation
l
Violation flags
l
Graphical one-line display of harmonic
results
l
Voltage & current harmonic spectrum plots
l
Bus driving point impedance scan curves
l
Updated one-line diagram (optional)
l
Fundamental load flow results
l
Recommendations for corrective action
