3) The no-load loss and exciting current on the rated voltage connection at 100 percent rated voltage shall be determined by test. 4) Polarity and phase relation tests shall be performed on the rated voltage connection. 5) The windings of transformer shall be given a one(1) minute, 60Hz applied potential test. 6) The windings of transformer shall be given an induced potential test. b. Design Tests 1) Full load temperature rise tests 2) Audible sound level tests 3) Lightning impulse dielectric test c. Other Tests/Examinations 1) Short circuit capability tests The Supplier shall provide the analysis or documentation of test results performed on the transformer to demonstrate the transformer meets the short circuit withstand requirements specified in KEPIC EEC 3100. 4-15 Spec. : 0-820-E204 Rev. 1 SECTION 4 - TECHNICAL SPECIFICATION 4.09 INSPECTION AND TESTING(CONT.)

2) Non-destructive Examinations Non-destructive examination (NDE) of the welds shall be visual, unless otherwise specified in this specification. The visual examination acceptance criteria for KEPIC SWS structural steel welds shall adhere to the requirements of NCIG-01. 2. Shop Inspection Inspection of the Materials/Equipment shall be at the Supplier's or Subsupplier's factory. Materials/Equipment shall not be shipped before Buyer has completed final inspection, and has issued the Supplier a release for shipment. The inspection or waiving of inspection by Buyer at the factory shall in no way relieve the Supplier of the responsibility of furnishing Materials/Equipment in accordance with this specification. Buyer's shop representative shall have access to the work specified herein, and shall have authority to refuse release for shipment, if, in the representative's opinion, the design, intent, or requirements of the specifications have not been fulfilled, or certified copies of required inspection and test data are not available for review. The representative shall indicate tests and inspections to be witnessed or performed after a review of the Supplier's work plan. Supplier shall give Buyer's representative seven working days advance notice and five working days advance confirmation on schedule

dates for performance of tests to be witnessed and on final inspection for shipment, per Attachment 4-2. One copy of the associated quality verification documents shall be attached to each transformer per Appendix 4E. 3. A sample of design test carried out on similar equipment with equivalent or higher rating can be accepted in place of carrying out the actual design test provided that the sample design test reports are reviewed and accepted by the buyer. 4.10 SHIPPING REQUIREMENTS A. GENERAL 1. The items procured by this specification are to be shipped, handled, stored, packaged and marked in accordance with Section 2 and subpart II.2 of KEPIC QAP-2. The KEPIC QAP-2, subpart II.2, classification of each item is designated below.
