About this file
The document is an introduction to a power quality study report for the Veterans Affairs Medical Center in Grand Junction, Colorado. The study aims to assess the reliability and safety of the hospital's electrical system through a comprehensive analysis that includes creating a one-line diagram, verifying equipment interrupting ratings, reviewing overcurrent protective device settings, conducting an arc flash analysis, and identifying potential maintenance or code variation issues.
The power system studies were performed using Easy Power Version 10.5 software to model the electrical system's physical properties and compute electrical characteristics. The data collection involved gathering information from multiple sources, including onsite discovery, equipment nameplates, manufacturer ratings, and utility data from the VA's Engineering Department. The primary focus was to determine short circuit current magnitudes, establish protective device coordination, and assess arc flash incident energy levels to ensure personnel safety at electrical equipment.

INTRODUCTION
The intent of this report is to describe the results of the power quality study for the existing electrical system at the Veterans Affairs Medical Center in Grand Junction, Colorado. This study was commissioned to ensure that the hospital’s power system is operating in a reliable and safe manner due to the critical nature of its day-to-day operation.
Project Scope
The study’s scope is the following:
Provide a one-line diagram of the studied electrical system.
Verify the interrupting ratings and the bracing of the electrical equipment is adequate for the exposure to fault currents Review and coordinate the settings of adjustable Overcurrent Protective Devices (breakers and fuses) to achieve optimum coordination within the limits of installed equipment.
Conduct an arc flash analysis study and provide equipment arc flash labels for field installation.
Review and comment on observed field conditions where maintenance and code variation may need attention.
Review and comment on notable situations revealed by the various studies.
Report Organization
Data Collection and Assimilation
The data collection and assimilation is comprised of data obtained by others, published information, through onsite discovery, equipment nameplate data, manufacturer rating, or other means. The site data was collected using personnel from Slocum Associates/SDV Services Inc. Utility data was obtained from the VA’s Engineering Department.
The collected system data is compiled and used to create an up-to-date one-line riser diagram of the system’s facilities, Power System Studies
The power system studies are performed to determine magnitude of short circuit currents throughout the electrical system; establish the relationship of protective devices as related to device coordination; and establish arc flash incident energy levels and personnel exposure to arc flash limits at equipment. Easy Power Version 10.5 is used to computer model the electrical system and is one the industry’s most respected software products for these applications. The program converts the electrical systems physical properties, such as wire sizes and lengths; transformer capacities; motor horsepower; etc. into their electrical equivalents. Then the various electrical computations are compiled based on the type of analysis required.
