APP 311L: SEL-311L Line Current Differential Relay

Description

SELU
Course Information

This is a two-day course.

Course Base Fees: $1,000 USD

APP 311L provides comprehensive application training for the SEL-311L Line Current Differential Relay, which offers complete line current differential protection with full scheme distance backup. In groups of two, students gain hands-on experience in communicating, metering, monitoring, commissioning, analyzing event reports, and performing control functions by working directly with the SEL-311L Relay.

Audience

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