Relay testing & commissioning training — online but still practical

Format: Virtual Classroom (Google Meet, Zoom/Teams) + Practical Demos + Simulation Software + Remote testing

Learning Objective 🎯

✔ Perform secondary injection relay testing (O/C, EF, Differential, Distance)
✔ Use real/virtual test set software for protection verification
✔ Analyze event/fault reports & troubleshoot misoperations

Fundamentals & Test Equipment

• Basics of protection relays
• Overview of commissioning process: wiring, CT/PT checks, safety
• Introduction to relay test sets
• Software tools for testing

Practical Demo: WE share screen + test set connection showing how to inject currents/voltages.

Relay Secondary Injection Testing

• Principle of secondary injection
• Current & voltage injection procedures
• Time-overcurrent (51/50) element testing
• Instantaneous vs inverse time characteristic testing

Hands-On (Remote): YOU inject current signals and record trip times

Differential & Distance Protection Testing

• Generator / Transformer differential (87) relay testing
• Slope settings, stability vs sensitivity tests
• Distance protection (21) – Zone testing using a test set

Fault Analysis & Troubleshooting

• Reading relay event reports, COMTRADE files
• Case study
• Common mistakes in testing & commissioning
• Analyzes a provided fault record
• Identifies correct operation vs misoperation
