Without reliable transmission capability, generation units throughout the BPS are useless. Transmission lines are highways allowing energy to travel from source to load to support customer demand. As such, protecting these lines is as critical as protecting systems that generate and distribute energy. Protecting these lines depends on:

• Properly loading transmission line relays
• Identifying the characteristics of overcurrent and ground faults
• Recognizing zone of protection and voltage instability protection

The Line Protection training course explains basic power system line relay loadability. It also discusses how to apply various protection methods to isolate faults on those lines. This online course includes:

• Transmission relay loadability
• Overcurrent protection
• Ground fault protection
• Distance relaying
• Voltage instability protection

This course is part of the System Protection training series.
