Product Overview

This Electrical Protection Trainer has been created for learning the dangers caused by touching electrical or electrical conductor equipment, simulation of protection of overcurrent, earth fault and earth leakage by using fault resistor. It is designed as a modular panel system with a 2 level mounting experiment frame. There are clear symbols on each panel by silk screen. All connecting points are via 4mm safety connectors for safety in operation.

A typical electrical protection relay syllabus covers the fundamentals of protective systems, various types of relays, and their applications in power systems. It includes topics like circuit breakers, fault analysis, protection schemes for different power system components (generators, transformers, transmission lines, etc.), and the principles of relay operation. The syllabus also explores aspects like over current protection, neutral grounding, and the use of digital and microprocessor-based relays.
