APP 710: SEL-710 Motor Protection Relay

Course Length: 2 Days (PDHs: 15)
Course Based Fees: $1,000*
* Plus Applicable Tax


In APP 710, students will explore how to use the SEL-710 Motor Protection Relay to protect induction motors in an industrial setting. Students will complete in-depth, hands-on application and settings examples to learn how they can implement complete motor protection and control.

Students will gain a comprehensive understanding of motor protection application philosophies, including SEL’s patented thermal model, which is integrated into the SEL-710. APP 710 includes real-world motor examples and reduced voltage and capacitor start applications. In groups of two, students gain hands-on experience in communicating, setting, commissioning, retrieving reports, and performing motor control functions by working directly with the SEL-710.


This course is intended for utility and industrial protection engineers and power system consultants.
