Short Circuit and Coordination Studies for Safe, Reliable, and Efficient Electrical Distribution Systems
The Purpose and Importance of Short Circuit Studies
System Reliability: Design robust electrical systems that can continue to operate safely and reliably under fault conditions by accurately determining the fault current levels.
Safety Assurance: Identify the potential fault currents that can occur within an electrical system so engineers can design systems that withstand and safely interrupt these faults, thus preventing damage to equipment and hazards to personnel.
Equipment Specification: Inform the selection of electrical components, such as circuit breakers, fuses, and switchgear, to ensure they have the appropriate interrupting capacity to handle the maximum possible fault current.
ULE Group’s Short Circuit Study Process
Data Collection: Gather detailed information about the electrical system, including one-line diagrams, equipment ratings, impedance values, and system configuration.
Fault Analysis: Use specialized software to simulate various fault conditions to calculate the prospective fault currents at different points in the system.
Evaluation and Reporting: Analyze all of the simulation results to identify potential issues and provide detailed reports that include recommendations for equipment ratings and system improvements.
The Purpose and Importance of Coordination Studies
Optimal Protection Settings: Ensure that protective devices operate in a coordinated manner to minimize the impact on the rest of the system.
Minimized Downtime: Provide proper coordination to ensure faults are isolated quickly and efficiently, reducing downtime and maintaining the continuity of electrical supply to unaffected areas.
Protection of Equipment: Prevent unnecessary tripping of upstream devices to protect critical equipment and reduce the risk of widespread outages.
ULE Group’s Coordination Study Process
System Analysis: Review the electrical system layout and protective devices in place, including their settings and characteristics.
Time-Current Characteristic (TCC) Curves: Develop TCC curves for each protective device to know their operating characteristics over various current levels and time durations.
Coordination Evaluation: Analyze the TCC curves to ensure there is a clear coordination between devices and adjust settings as necessary to achieve selective tripping.
Documentation and Implementation: Document the recommended settings and any changes, and implement these adjustments in the field to achieve the desired level of protection and coordination.
