New Electrical Equipment
Process Industry Practices Page 5 of 23
4.5 The Tester shall be responsible for maintaining the individual test sheets and the
project master checkout sheet as defined in the project scope. These sheets shall be
maintained in an up-to-date condition and are subject to review at any time. These
sheets shall be submitted to the Owner’s project electrical representative in final
format at the completion of the project.
4.6 All components with test results that fall outside the acceptable range and individual
measurements that fall outside the average of like measurements by 25 percent
difference shall be immediately brought to the Owner’s attention.
4.7 Inspection items, testing, and function test items shall be witnessed by an Owner’s
authorized representative unless specifically waived in writing. Tester shall give
sufficient notice before any witnessed test.
4.8 Copies of the test results shall be submitted in preliminary form to the Owner’s
authorized representative within five (5) working days after each test. These
preliminary results shall be submitted and approved by Owner before placing any
equipment in operation.
4.9 Tester shall transmit all final testing forms to the Owner.
5. Acceptable Measurements
5.1 Insulation resistance tests shall be made at the following voltages with respect to the
circuit voltage rating:
Volts DC Circuit Rating (V)
500 0 - 300 volts
1000 301 - 600 volts
2500 601 - 2500 volts
5000 2501 volts and above
All circuit conductors shall be tested phase to phase and phase to ground. A phase-
to-ground test on shielded cable shall mean "conductor to shield." Insulation
resistance for wire and cable shall be corrected to 60°F (15.6°C). Insulation
resistance for all other equipment items shall be corrected to 104°F (40°C). The
measured insulation resistance values shall not be less than the following values.
5.1.1 Motors:
460 volt, cold machine 15 megohms
2300 volt, cold machine 25 megohms
Above 2300 volt, cold
machine
75 megohms
5.1.2 Transformer windings in which all windings are grounded except the one
under test:
