Common use of Tests Prior to Synchronization of the Complex Clause in Contracts

Tests Prior to Synchronization of the Complex. Prior to synchronization of the Complex with the Grid System, the Engineer shall deliver to the Company and the Power Purchaser and NTDC the Certificate of Readiness for Synchronization. Prior to the delivery of the Certificate of Readiness for Synchronization and the first synchronization of the Complex, the Company shall carry out, or shall cause the Contractors to carry out, in the presence of the Engineer, the following tests: (a) automatic voltage regulator setting and adjusting in stand still condition and with the generator running at no load; (b) turbine/engine governor control checks, including a steam governor over speed test; (c) open and short circuit tests on each generator; and (d) functional testing and timing of high voltage switchgear in the switchyard of the Complex. (e) The Company and NTDC shall verify that the protection level settings for the following are as agreed by the Operating Committee: (i) stator earth fault; (ii) negative phase sequence; (iii) generator transformer over-current and earth fault; and (iv) high voltage bus-bar protection. (f) Voltage phasing checks will be carried out between the sub-station of the Complex and the Grid System. (g) All inter-tripping circuits between the Complex and the NTDC’s equipment will be proved. The Power Purchaser and NTDC shall be given not less than twenty-four (24) hours notice of such tests (and any retests thereof) and shall have an opportunity to be present at and observe all such tests.
