1. Design and Implementation of Protection Systems:
Design Protection Schemes: Protection engineers design protection systems to detect faults and isolate affected parts of the electrical network. This includes designing systems for circuit breakers, relays, fuses, and other protection devices that automatically trip when an abnormal condition is detected.
Select Appropriate Protection Equipment: Choose the right protection devices (e.g., overcurrent relays, differential relays, distance relays) based on the type of electrical system and operational requirements. They must ensure the equipment is reliable and operates within defined parameters.
System Coordination: Coordinate protection schemes across different parts of the network to ensure that faults are isolated in the most efficient way possible, minimizing disruption to the power supply and protecting both equipment and people.
2. Fault Analysis and Troubleshooting:
Analyze Faults: Protection engineers perform fault analysis to determine the causes of faults in the system. They analyze fault data (voltage, current, etc.) and investigate system behavior during faults to identify weaknesses and improve system reliability.
Troubleshoot Protection Systems: Diagnose and troubleshoot problems with protection systems, ensuring that protective relays, circuit breakers, and other components are functioning as expected. This includes performing tests and checks on protective equipment to verify their settings and operations.
3. System Coordination and Optimization:
Protection Coordination: Ensure that protection settings are coordinated across multiple devices and systems to achieve selective fault isolation. This minimizes downtime and ensures that only the affected part of the network is disconnected, while the rest remains operational.
Optimize Settings: Continuously review and optimize protection settings to improve the reliability and speed of fault detection and isolation. Protection engineers must consider factors like system load, fault current, and network topology to fine-tune settings for efficient performance.
4. Testing and Commissioning:
System Testing: Protection engineers are responsible for testing protection systems to ensure they operate correctly before and after installation. This includes performing functionality tests, verifying settings, and simulating fault conditions to ensure proper response.
Commissioning Protection Systems: During the commissioning of new electrical systems or upgrades, protection engineers ensure that all protection devices are installed and set up correctly. This includes verifying that protection devices are correctly integrated into the system and that they operate as designed during real-world scenarios.

Maintenance and Upgrades:
Routine Maintenance: Regularly inspect and maintain protection equipment, including relays, circuit breakers, and control panels. This ensures that all systems are in optimal working condition and capable of protecting the system when needed.
Upgrades and Replacements: Recommend and implement upgrades to protection systems, particularly in response to changes in the electrical network, new technology, or regulatory requirements. Replace or update outdated protection devices to ensure compatibility and improve system performance.
Safety and Compliance:
Ensure Safety Standards: Protection engineers are responsible for ensuring that electrical systems comply with safety regulations and standards. This includes adhering to industry standards such as those set by the IEEE, IEC, and ANSI to ensure system safety.
Risk Management: Identify and mitigate potential risks associated with electrical faults, such as equipment damage, fires, or electrical hazards. Implement preventive measures to reduce the likelihood of accidents or failures.
