This 12-Hour (2 Day) Short Circuit Study & Protective Device Coordination Study live online instructor-led course gives students an understanding of what is involved in performing both a Short Circuit Study and a Protective Device Coordination Studies on industrial, commercial and institutional power systems.
This course can be taken with our Arc Flash Study Training course
Short Circuit Study & Protective Device Coordination
A power system study is an extremely important document for any power system. Even small power systems are having power system studies performed to comply with more stringent codes and regulations. Due to the high reliability requirement imposed upon the operation of data centers it is an absolute necessity.
A power system study typically consists of three studies: Short Circuit Study, Protective Device Coordination Study, and Arc Flash Study. While these individual studies may sometimes be considered separately, they are very much interrelated. It is therefore recommended that these studies be performed at the same time, by the same engineer(s), to ensure the most accurate results.
Short Circuit Study
The purpose of a short circuit study is to identify the maximum available fault current at all locations, called busses, in the power system. It is then compared with the ratings of the individual power system components to determine if the equipment is adequately rated to safely withstand or interrupt the calculated fault current. The results of the short circuit study are also used in both the coordination study and the arc-flash study.
Protective Device Coordination Study
The purpose of a protective device coordination study is to determine the proper settings for overcurrent protective devices in the power system. Ideally, the selection of the proper settings will both protect the power system equipment as well as remove only the smallest portion of the electrical system as necessary from service in order to isolate a fault. In most cases however compromises must be made in order to provide the best overall system reliability.
A Short Circuit Study is the analysis of an electrical system that determines the magnitude of the currents that flow during an electrical fault. Comparing these calculated values against the equipment ratings is the first step to ensuring that the power system is safely protected. Once the expected short circuit currents are known, a Protective Device Coordination Study is performed to determine the optimum characteristics, ratings, and settings of the power system protective devices.
This Short Circuit Study & Protective Device Coordination Study course gives students an understanding of what is involved in performing both a Short Circuit Study and a Protective Device Coordination Study.
The Short Circuit Study course module will provide students with an understanding of how to calculate short circuit levels on three phase power systems. One of the important purposes of calculating short circuit levels is to facilitate the application and setting of protective relays.
This Short Circuit Study course module will present the fundamentals of power system protection so that attendees will understand:
The Protective Device Coordination Study course module will provide students with an understanding how overcurrent protection is applied to power distribution systems.
This course will present the fundamentals of distribution system protection so that attendees will understand:
Short Circuit Study & Protective Device Coordination course is designed for utility, industrial, commercial and institutional power system electrical engineering personnel, electrical consulting engineers, as well as electrical design engineers, who are responsible for the reliable design, engineering and operation and of industrial, commercial and insitutional electric power distribution systems. Plant, facility, and corporate electrical engineers dealing with one or more company distribution systems and consulting and utility engineers dealing with clients' systems. Consultants, architect-engineers will also find this course very beneficial.
