Bid Package 08 North Well Field - Garney Construction

a. Perform insulation resistance test on 5KV cable for insulation resistance tested at
2,500 volts with respect to ground and at 2,500 volts with respect to all other
conductors in each circuit.
b. H‐Pot test 5KV cables incrementally to 25 KVDC for 15 minutes per ANSI/IEE STD
400. Record leakage current in the spaces provided, at the time intervals shown, on
the "Medium Voltage Cable Test Report." Do not exceed the cable Supplier’s
maximum test values or procedures.
c. Perform Individual conductor resistance tests and recorded results. Test each
circuit for continuity between terminations ends and record the test results.
Provide additional tests and checks as requested by the Supplier.
4. 15kv Cable And Conductors:
a. Perform insulation resistance test on 15KV cable at 2500 volts with respect to all
other conductors in each circuit.
b. H‐Pot test 15KV cable incrementally to 55KVDC for 15 minutes per ANSI/IEE STD.
400. Record leakage current at the time interval, shown, on the "Medium Voltage
Cable Test Report." Do not exceed the cable Supplier's recommended maximum
test values or procedures. Perform individual conductor resistance tests and record
the results. Test each circuit for continuity between terminating ends and record
the results. Provide additional tests and checks as required by the Supplier.
F. Switchgear
1. Test electrical switchgear and electrical devices and controls mounted on or in the
switchgear in accordance with the "Switchgear Test Report" form.
2. Record the following information and attach to the test report:
a. Resistance reading across joints of each horizontal and vertical bus.
b. Verify proper operation of electrical, mechanical and keyed interlocking systems.
c. Operate devices at both their open and closed states. Operate stored energy
devices mechanically and electrically as applicable. Operate remotely controlled
devices from their remote location.
d. Verify proper operation of draw‐out circuit breakers and switches. Remove and reinstall
each unit. Verify proper operation of shutters and barriers.
e. Disconnect electrical and electronic sensing and protective devices not rated to
withstand insulation resistance test potentials. Reconnect the devices before
energizing the switchgear.
f. Perform insulation resistance tests at the test voltages shown below for the
following equipment. Do not exceed the Supplier's recommended maximum test
values or procedures.
