2.6.2.13
Harmonic Distortion
Harmonics generated by the insertion of a filter shall not increase line
voltage distortion more than 2.5 percent when measured with a unity power
factor in accordance with the paragraph ELECTORMAGNETIC FILTERS.
2.6.3
Marking of Filter Units
Each filter case shall be marked with HCI tags and with the rated current,
rated voltage, manufacturer s name, type of impregnating or potting
compound, operating frequency, and model number. In addition, individual
filter cases, the filter enclosures, and supply and load panelboards of
filtered circuits shall be marked by the manufacturer with the following:
"WARNING: Before working on filters, terminals must be temporarily
grounded to ensure discharge of capacitors. Nameplates and warning labels
shall be securely attached.
2.6.4
Minimum Life
Filter assemblies shall be designed for a minimum service life of 15 years.
2.6.5
Power and Signal Line Factory Testing
**************************************************************************
NOTE: In most cases, test results for equal filters
are sufficient to determine compliance with
specification requirements. Factory tests on
individual filters may be required for higher than
average temperature applications, special filter
configurations, and other special project
requirements.
Filters with nonstandard configuration or ratings
may require testing by an independent testing
organization. These ratings would be for filters
above 1,000 amperes.
**************************************************************************
Factory test report data shall be submitted for each filter configuration,
voltage, and amperage which shall show the ability of filters to meet the
specified requirements. Filter test reports shall be based on prior tests
of the same filter assembly design and components. Test data reports shall
be submitted in accordance with paragraph SUBMITTALS. Test data shall
include the following:
a.
Voltage Drop Measurements.
b.
c.
Filter Life Test.
d.
Thermal Shock Test.
e.
f.
Reactive Shunt Current Measurements.
g.
Dielectric Withstand Voltage.
