Pertinent data and the rationale employed in developing the calculations shall be incorporated in the introductory remarks of the study. 3. Present the data determined by the short circuit study in a table format. Include the following: a. Device identification. b. Operating voltage. c. Protective device. d. Device rating. e. Calculated short circuit current. D. Coordination Curves: 1. Prepare the coordination curves to determine the required settings of protective devices to assure selective coordination. Graphically illustrate on log log paper that adequate time separation exists between series devices, including the utility company upstream device. Plot the specific time current characteristics of each protective device in such a manner that all upstream devices will be clearly depicted on one sheet. 2. The following specific information shall also be shown on the coordination curves: a. Device identification. b. Voltage and current ratio for curves. c. 3 phase and 1 phase ANSI damage points for each transformer. d. No damage, melting, and clearing curves for fuses. e. Cable damage curves. f. Transformer inrush points. g. Maximum short circuit cutoff point. 3. Develop a table to summarize the settings selected for the protective devices. Include the following in the table: a. Device identification. b. Relay CT ratios, tap, time dial, and instantaneous pickup. c. Circuit breaker sensor rating, long time, short time, and instantaneous settings, and time bands. d. Fuse rating and type. e. Ground fault pickup and time delay. 5. ANALYSIS A. Analyze the short circuit calculations and highlight any equipment that is determined to be underrated as specified. Propose approaches to effectively protect the underrated equipment. Provide minor modifications to conform with the study (Examples of minor modifications are trip sizes within the same frame, the time curve characteristics of induction relays, C.T. ranges, etc.). B. After developing the coordination curves, highlight areas lacking coordination. Present a technical evaluation with a discussion of the logical compromises for best coordination. ADJUSTMENTS, SETTINGS AND MODIFICATIONS Necessary final field adjustments, settings and minor modifications shall be made to conform with the protective device study without additional cost to the Government. All final circuit breaker and relay settings and fuse sizes shall be made in accordance with the recommendations of the protective device study. Equipment List: The above procedures are to be implemented to all electrical equipment listed in the attached electrical studies for both Divisions. If an electrical equipment exists in the facility but does not show in the attached study, provide testing and maintains to equipment, and mark equipment s information and location on a hard copy of the attached studies. Provide marked copies with report upon completion. Workmen are subject to normal Medical Center rules: Smoking is not permitted on VA property Parking. One vehicle is authorized to load and unload material and equipment at loading docks. All other vehicles must park in Contractor designated area or as directed by Electronics Shop Supervisor.
