Study Report
a.
The report shall include a narrative describing: the analyses
performed; the bases and methods used; and the desired method of
coordinated protection of the power system.
b.
The study shall include descriptive and technical data for
existing devices and new protective devices proposed. The data
shall include manufacturers published data, nameplate data, and
definition of the fixed or adjustable features of the existing or
new protective devices.
c.
The report shall document [utility company data including system
voltages, fault MVA, system X/R ratio, time-current characteristic
curves, current transformer ratios, and relay device numbers and
settings;] [and] [existing power system data including
time-current characteristic curves and protective device ratings
and settings.]
d.
The report shall contain fully coordinated composite time-current
characteristic curves for each bus in the system, as required to
ensure coordinated power system protection between protective
devices or equipment. The report shall include recommended
ratings and settings of all protective devices in tabulated form.
e.
The report shall provide the calculations performed for the
analyses, including computer analysis programs utilized. The name
of the software package, developer, and version number shall be
provided.

FACTORY TESTS
**************************************************************************
NOTE: Delete tests that are not applicable to the
project. Refer to TM 5-811-1/AFM 88-9 Chapter 1 for
guidance. Tests must be justified. Delete
transformer losses test when losses are not
specified.
**************************************************************************
Factory tests shall be performed, as follows, in accordance with the
applicable publications and with other requirements of these
specifications. The Contracting Officer shall be notified at least [10]
[_____] days before the equipment is ready for testing. The Contracting
Officer reserves the right to witness the tests.
a.
Power Transformer: Manufacturer's standard [routine] [design]
[and] [other] tests in accordance with IEEE C57.12.00.
b.
Power Transformer: Reduce full-wave, chopped-wave, and full-wave
impulse test on each line [and neutral] terminal, in accordance
with IEEE C57.98.
c.
Power Transformer: Tests for transformer losses in accordance
with IEEE C57.12.90.
d.
High-Voltage Circuit Breakers: Manufacturer's standard tests in
accordance with IEEE C37.09 and IEEE C37.081.
