APP 300G: SEL-300G Generator Relay

This course provides complete application training for the SEL-300G Generator Relay, an extremely flexible protective relay used worldwide for protection and monitoring of all sizes of synchronous generators. Working directly with an SEL-300G in groups of two, you will gain hands-on experience in communicating with the relay, applying settings, metering, monitoring, retrieving event reports, and performing control functions.

Audience

APP 300G is designed for utility and industrial protection engineers and power system consultants.

Student Background and Knowledge

Before you attend this class, we recommend that you:

• Complete CBT 101: Introduction to SEL Relays OR have a basic familiarity with protective relaying, SELogic control equations, front-panel controls, and the SEL-4000 Relay Test System.
• Have the ability to set up a communications session using an ASCII terminal emulation program.

Course Preparation

Install or update the following software/files on the laptop you are bringing to class:

• acSELerator QuickSet SEL-5030 Software (include all device drivers during installation).
• SEL-C662 USB driver.
• SEL-5401 Software.
• SEL-300G instruction manual.

Please ensure that your laptop does not have any installation blocks before you come to class.
