Digital Relay & Testing
3 Days / 24 Hours
Laboratory Simulation + Hands-on with Relay Test Sets
Rapid isolation of short-circuit faults in electrical transmission and distribution networks depends on the accurate configuration of secondary protection relays. In this training, engineers gain hands-on experience with programming digital relays, performing injections with secondary test sets, and ensuring coordination selectivity on actual devices.
Target Audience
Electrical-Electronics Engineers, protection department engineers, automation specialists.
Certification
Secondary Protection and Relay Testing Certificate of Expertise
Training Outcomes and Competencies
- ANSI protection codes (50/51, 50N/51N, 87T, 21, 59, 27, 81) and operating logic
- Interface software for modern digital relays (Siemens Siprotec, Schneider Sepam, ABB Relion)
- Current-voltage injection and trip time verification using Omicron / Doble relay test sets
- Selectivity calculations and plotting of relay coordination curves
- Analysis of event logs and fault oscillograms (COMTRADE)
