b.
Electrical Tests
(1) Perform insulation-resistance test on each conductor with
respect to ground and adjacent conductor; applied potential shall
be 1000 volts DC for 1 minute; minimum insulation-resistance
values shall not be less than 2 megohms.
(2)
Perform continuity test to insure proper cable connection.
3.2.1.2
Medium Voltage Cables
Perform tests after installation of cable, splices, and terminators and
before terminating to equipment.
a.
Visual and Mechanical Inspection
(1)
Inspect exposed cable sections for physical damage.
(2) Verify that cable is supplied and connected in accordance
with contract plans and specifications.
(3) Inspect for proper shield grounding, cable support, and cable
termination.
(4) Verify that cable bends are not less than ICEA or
manufacturer's minimum allowable bending radius.
(5)
Inspect for proper fireproofing.
[(6) If cables are terminated through window-type CT's, make an
inspection to verify that neutrals and grounds are properly
terminated for proper operation of protective devices.]
(7)
Visually inspect jacket and insulation condition.
(8)
Inspect for proper phase identification and arrangement.
b.
Electrical Tests
(1) Perform a shield continuity test on each power cable by
ohmmeter method. Record ohmic value, resistance values in excess
of 10 ohms per 1000 feet of cable must be investigated and
justified.
(2) Perform a DC high-potential test on all cables. Adhere to
precautions and limits as specified in the applicable NEMA/ICEA
Standard for the specific cable. Test procedure shall be as
follows, and the results for each cable test shall be recorded as
specified herein. Field acceptance test voltage [for 5 kV cable
shall be 25 kV DC] [and] [for 15 kV cable shall be [[55] [65] kV
DC] [53 kV DC with insulated connectors]] [and] [for 25 kV cable
shall be [[80] [100] kV DC] [78 kV DC with insulated connectors]]
[and] [for 35 kV cable shall be 100 kV DC].
