Module 6 : Distance Protection Lecture 21 : Introduction to Distance Relaying Objectives In this lecture we will Introduce distance protection. Discuss advantages of distance protection. Fault modeling of
The protective relays act only after an abnormal or intolerable condition has occurred, with sufficient indication to permit their operation.
Distance Protection Relay: Distance relays are used for transmission line protection. They measure the impedance or reactance of the line and operate if a fault occurs within a predefined distance.
This paper discusses how the use of microprocessor based protection relays and modern digital communication technologies have simplified transmission line protection. The paper also discusses
A primary motor protective element of the motor protection relay is the thermal overload element and this is accomplished through motor thermal image modeling. This model must account for thermal
