Maximizing Line Protection Reliability, Speed, and Sensitivity
Originally presented at the 42nd Annual Western Protective Relay Conference, October 2015, under the title “Maximizing Line Protection Reliability, Speed, and Security”
Relay protection sensitivity requirements are
Every protection system which isolates a faulty element is required to satisfy four basic requirements: (i) reliability; (ii) selectively; (iii) sensitivity; and (iv) speed of operation. For example, unselective protection operation during a medium voltage network fault will cause an outage for an unnecessarily large number of consumers. While this is bad, It's not a. Protective relays and devices have been developed over 100 years ago to provide “lastline”of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. The sensitivity should be sufficient to ensure reliable protec-tion d...

Protective Relay Basics
Traditionally, protective relays were electromechanical devices utilizing induction disk, coils, contacts, and solenoid elements to determine protective characteristics.
Sensitivity of a Relay
Sensitivity of a Relay The relay in a protection system should be sensitive enough to operate when a fault occurs. A sensitive relay improves the reliability of the system. When the parameter exceeds the
Basic Requirements of Protection System
The smaller the volt-ampere input required to cause relay operation, the more sensitive is the relay. A protection with high degree of sensitivity is more complex
Module 1 : Fundamentals of Power System Protection
Like sensitivity, selectivity also implies an ability to discriminate. A relay should not confuse some peculiarities of an apparatus with a fault. For example, transformer when energized can draw up to
ASSESSING THE SENSITIVITY OF RELAY PROTECTION
One of the main requirements to relay protection is the sensitivity requirement, which implies consistent tripping during the short circuit (s c) events in the protected zone .
