PROT 415: Time-Domain Line Protection

Overview

This course is intended for utility transmission protection engineers and power system consultants who need a comprehensive understanding of the new ultra-high-speed time-domain line protection principles and applications.

After a refresher of power system faults and protection concepts, PROT 415 provides an in-depth study of incremental-quantity-based line protection elements. The course also covers traveling-wave protection elements and schemes in detail. Finally, the course covers fault-locating methods, including the new, highly accurate methods based on traveling waves launched by faults.
