This is a two-day course.
Course Base Fees: $1,000 USD
In this two-day course, 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 Motor Protection Relay. 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.
