Box 1265 Arvada, CO 80001 Arvada, CO 80001 Abstract - This paper presents some general procedures for the However, some equipment suppliers may claim to test the proper inspection, testing, and start-up of critical, but often switchgear but in fact may not truly perform comprehensive overlooked, electrical items in substations and medium voltage testing. The switchgear is disassembled for shipment, and then switchgear commonly found in petro-chemical facilities. The reassembled at the job site. The result may be the creation of paper emphasizes procedures for protective relay and circuit many mechanical and electrical problems. Start-up lists and test breaker control circuit testing. Practical methods for testing procedures, including IEEE standards [2] [3] [5] [6], testing current and potential circuits, which are the critical sensing organization procedures, electric utility procedures, and inputs for most protective relaying
