COMMISSIONING OF THE WORKS Sample Clauses

COMMISSIONING OF THE WORKS. The Contractor shall perform Commissioning of the Works, as further detailed in Appendix 1B.

COMMISSIONING OF THE WORKS. 1.34.1 When installation stage is complete, The Contractor must submit operating manual to The Employer and as-built drawings within 7 days. An appointment date for commissioning must be arranged by The Contractor with 2 weeks after submitting operating manual and as-built drawings. During commissioning the following checks are to be done: ✓ Verification and calibration of oil (i.e. if applicable) and winding instruments ✓ Verification of functionality of cooling fan start signals, alarms and trip signals. ✓ Cooling equipment checks. ✓ Check control circuit cabling and auxiliary power cabling. ✓ Checking of pressure relief valve (i.e. if applicable) ✓ Checking of rapid rise pressure relay. ✓ Checking of tap changer over pressure switch. 1.34.2 A checklist page prepared by The Contractor is to be used to tick each step of commissioning process by stakeholders and The Employer can issue a snag list to The Contractor after this process, of which The Contractor must fix within a period agreed between two parties. No payments are to be made by The Employer until all snags are completed and snag list signed off by The Project Manager. 1.34.3 When checks and visual snags are completed, the following tests are to be completed by The Contractor: ✓ Swept frequency response analysis (SFRA) ✓ Ratio, polarity, and vector group verification. ✓ Tan delta/Power Factor/Dielectric dissipation factor and capacitance tests on winding. ✓ Excitation/Magnetising current tests. ✓ Impedance/Leakage reactance test. (Compare to nameplate and factory tests) ✓ Zero sequence impedance tests ✓ Insulation resistance test on windings, core, and frame to earth (i.e., Megger) ✓ Current transformer testing. 1.34.4 The Contractor must submit test certificates to The Employer within two weeks after commissioning. The Employer is to pay maximum 75% the contract value before commissioning, as per cost projections and actual work completed in stages of the project. However, the remaining 25% will be paid to The Contractor 30 days after successful commissioning date and completion of snags (i.e., provided no faults occur in before 30 days is depleted).
