R in megohms = (rated voltage in kV + 1) x 304,800/(length of cable in
meters)
R in megohms = (rated voltage in kV + 1) x 1000/(length of cable in feet)
Each cable failing this test shall be repaired or replaced. The repaired
cable shall then be retested until failures have been eliminated.

Liquid-Filled Transformer Tests
The following field tests shall be performed on liquid-filled transformers
[[_____] kVA and above]. Pass-fail criteria shall be in accordance with
the transformer manufacturer's specifications.
a.
Insulation resistance test phase-to-ground.
b.
Turns ratio test.
c.

3.11.8
Pre-Energization Services
The following services shall be performed on the equipment listed below.
These services shall be performed subsequent to testing but prior to the
initial energization. The equipment shall be inspected to insure that
installation is in compliance with the recommendations of the manufacturer
and as shown on the detail drawings. Terminations of conductors at major
equipment shall be inspected to ensure the adequacy of connections. Bare
and insulated conductors between such terminations shall be inspected to
detect possible damage during installation. If factory tests were not
performed on completed assemblies, tests shall be performed after the
installation of completed assemblies. Components shall be inspected for
damage caused during installation or shipment and to ensure that packaging
materials have been removed. Components capable of being both manually and
electrically operated shall be operated manually prior to the first
electrical operation. Components capable of being calibrated, adjusted,
and tested shall be calibrated, adjusted, and tested in accordance with the
instructions of the equipment manufacturer. Items for which such services
shall be provided, but are not limited to, are the following:
Automatic circuit reclosers.
Capacitors.
Switches.
Transformers.
3.11.9
Operating Tests
After the installation is completed, and at such time as the Contracting
Officer may direct, the Contractor shall conduct operating tests for
approval. The equipment shall be demonstrated to operate in accordance
with the specified requirements. An operating test report shall be
submitted in accordance with paragraph SUBMITTALS.
