Why Choose this Training Course?
Why Choose this Course?
Protection systems are installed in power system to prevent damages of electrical equipment by faults, to isolate a faulty part, and to maintain continuity of supply elsewhere in the system. Modern protection includes multiple protection functions as well as monitoring and recording features, self-diagnostics and analogue and digital data. Although the primary role of protective relays is to perform protection functions, relays also provide additional data and some control functions.
The Protection Relay Application online training course is interactive and encourages delegates to participate through questions and answers. Case studies help further in better understanding the discussed topics.
The Protection Relay Application online training course will cover the following:
- Power System Fault Analysis
- Current and Voltage transformers
- Protection Concept
- Over Current and Earth Fault Protection
- Pilot Wire and Distance Protection
- Transformer Protection
- HV Circuit Breakers principle of operation and maintenance
- Principles of LV motor starts protection and maintenance
