2.26.1
Transformer Test Schedule
The Government [reserves the right to] [will] witness tests. Provide
transformer test schedule for tests to be performed at the manufacturer's
test facility. Submit required test schedule and location, and notify the
Contracting Officer 30 calendar days before scheduled test date. Notify
Contracting Officer 15 calendar days in advance of changes to scheduled
date.
a.
Test Instrument Calibration
(1) The manufacturer shall have a calibration program which
assures that all applicable test instruments are maintained within
rated accuracy.
(2) The accuracy shall be directly traceable to the National
Institute of Standards and Technology.
(3) Instrument calibration frequency schedule shall not exceed 12
months for both test floor instruments and leased specialty
equipment.
(4) Dated calibration labels shall be visible on all test
equipment.
(5) Calibrating standard shall be of higher accuracy than that of
the instrument tested.
(6) Keep up-to-date records that indicate dates and test results
of instruments calibrated or tested. For instruments calibrated
by the manufacturer on a routine basis, in lieu of third party
calibration, include the following:
(a) Maintain up-to-date instrument calibration instructions and
procedures for each test instrument.
(b) Identify the third party/laboratory calibrated instrument to
verify that calibrating standard is met.
2.26.2
Routine and Other Tests
IEEE C57.12.00 and IEEE C57.12.90. Routine and other tests shall be
performed by the manufacturer on [each of] the actual transformer(s)
prepared for this project to ensure that the design performance is
maintained in production. Submit test reports, by serial number and
receive approval before delivery of equipment to the project site.
Required tests shall be as follows:
a.
Polarity
b.
Ratio
c.
No-load losses (NLL) and excitation current
d.
Load losses (LL) and impedance voltage
e.
Dielectric
(1)
Impulse
