Transmission line protection is the coordinated use of protective relays, instrument transformers, circuit breakers, communication channels, and backup logic to detect faults on high-voltage lines and isolate the affected section. presentation of protection and control relaying. 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. A typical protective relay circuit is shown below: Protective Relay Circuit Diagram The first part of the circuit consists of the primary winding of a CT. The components used in the power system are usually dimensioned to withstand a short circuit current for one or three seconds but power system stability during short circuit current may be endangered already after 200ms. A protection scheme – for example, a differential protection scheme – is.

This list of highest bridges includes bridges with a deck height of at least 250 metres (820 ft). The deck height of a bridge is the maximum vertical drop distance between the (the road, rail or other transport bed of a bridge) and the ground or water surface beneath the bridge span. Deck height is different from structural height, which is a measure of the maximum v.
