Level 2 Relay Protection Certificate

The Level 2 Relay Protection Certificate certifies competency in testing and commissioning all distribution protection schemes, including protection of distributed generators and advanced relay systems.

Overview

The Level 2 Relay Protection Certificate is designed for engineers and technicians responsible for testing and commissioning protection systems in electrical distribution networks, typically up to 132kV . It ensures that participants have the skills to handle complex protection schemes, including directional overcurrent/earth fault relays, distance protection relays, transformer differential, busbar differential, line differential, and restricted earth fault protection .

Competency Requirements

To achieve Level 2 certification, candidates must demonstrate proficiency in:

• Testing and commissioning protection systems at voltages up to 11kV, including CTs, VTs, AC/DC scheme wiring, and switchgear trip/close circuits .
• Configuration and testing of pole-mounted auto-reclose equipment and distributed generator protection functions .
• Testing of power transformers, circuit breakers, control and relay panels, and backup protection systems .
• Design or modification of relay logic and performing stability tests for transformer differential, line differential, busbar differential, and restricted earth fault protection .

Training and Practical Experience

Level 2 certification typically requires hands-on training with both electromechanical and microprocessor-based relays. Training programs, such as those offered by AVO Training Institute, provide:

• Practical exercises on overcurrent, bus differential, transformer differential, undervoltage, overvoltage, and harmonic restraint relays .
• Interpretation of AC and DC relay schemes and proper relay maintenance, adjustment, and calibration using state-of-the-art test sets .
• Understanding of NETA testing standards and recording of test results . Courses may range from intensive multi-day lab-oriented sessions to modular online training, covering both theory and real-world application .

Benefits of Certification

Holding a Level 2 Relay Protection Certificate demonstrates that an engineer or technician can:

• Safely and accurately commission and test complex protection systems.
• Ensure system reliability and stability in distribution networks.
• Apply protection schemes to distributed generation and advanced relay configurations.
• Reduce downtime and prevent miscoordination or misoperation of protective devices .

Conclusion

The Level 2 Relay Protection Certificate is a professional credential for electrical engineers and technicians who work with advanced distribution protection systems. It combines practical hands-on training, theoretical knowledge, and competency assessment to ensure that certified personnel can maintain, test, and commission protection schemes effectively and safely .
