In this engaging lecture on Time-Distance Impedance Relays, we delve into their essential function in the protection of electrical power systems, particularly in safeguarding transmission lines from faults. The session provides an in-depth look at the fundamental concepts of impedance measurement and how these relays determine the distance to a fault based on changes in impedance. We will examine the operational mechanisms of Time-Distance Impedance Relays, including their time-delay features that allow for effective coordination with other protective devices.
