This is a two-day course.
Course Base Fees: $1,000 USD
APP 351 provides comprehensive application training for the SEL-351 Protection System, an extremely flexible protective relay used by utilities worldwide, in multiple applications. Working in groups of two, students gain hands-on experience in communicating, setting, metering, monitoring, retrieving event reports, and performing control functions by working directly with the SEL-351S Relay.
Audience
This course is designed for utility and industrial protection engineers and power system consultants.

Course Objectives
At the conclusion of this course, students can:
- Apply the SEL-351S Relay protection, monitoring, and control features.
- Communicate with the relay through the front panel and serial port.
- Use QuickSet to apply relay settings, program SELogic control equations, and analyze fault records and the relay element response.
- Analyze Sequential Events Recorder (SER) reports.
- Implement relay-to-relay logic communications via the Mirrored Bits communications protocol.
- Identify multiple applications for the SEL-351 Relay family.
- Differentiate between SEL-351, SEL-351A, and SEL-351S Relay features.
Student Background and Knowledge
Before you attend this class, we recommend that you:
- Have basic familiarity with protective relaying, SELogic control equations, QuickSet, front-panel controls, and the SEL‑4000 Relay Test System.
- Have the ability to set up relay communications using acSELerator QuickSet SEL-5030 Software.
- Complete CBT 101: Introduction to SEL Relays (highly recommended).
