PROT 415: Time-Domain Line Protection

Course Length: 2 Days (PDHs: 15)
Course Based Fees: $1,200 *
* Plus Applicable Tax

Description

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.

Audience

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.
