350-07 - Pilot Protection
Learning objectives
- Recall why pilot protection systems are needed
- Identify the strengths and weaknesses of the major communications channels
- Identify which communications mediums are capable of high bandwidth data transmission
- Identify the differences between permissive, blocking, and direct transfer trip schemes
- Recall how pilot protection both manipulates and makes use of time delays
- Define the difference between overreaching and under-reaching schemes
Course overview
System protection monitors system parameters to identify abnormal and unacceptable conditions. If one of those conditions occurs, system protection takes appropriate action to avoid any system damage. Time delays are used to ensure coordination between all system elements when a fault occurs. Pilot protection is used to avoid extended system damage by quickly identifying the fault, taking appropriate action, and bypassing the time delay.
The Pilot Protection training course explains the major communication channels used by this protection. It also describes the basic functions of the common pilot protection schemes deployed in power system protection. This online course covers:
- Pilot protection introduction
- Communication channels
- Pilot schemes
Pilot Protection is part of the System Protection training series.
