One mitigation technique is to add a synchronism-check function to all protective relays that potentially connect two systems together.
12.
Some suggested methods include adding functionality in protective relays to ensure synchronism and adding a time delay for closing breakers.
13.
Electromechanical protective relays are used to detect overload and other faults on electrical lines by opening and closing circuit breakers.
14.
A significant part of Dr . Gurevich's work is also devoted to the problem of reliability of digital protective relays.
15.
In higher powered applications, the protective relays that detect a fault and initiate a trip are separate from the circuit breaker.
16.
In electrical engineering, a "'protective relay "'is a relay device designed to trip a circuit breaker when a fault is detected.
17.
It is possible to program customised curves in some protective relays and other manufacturers have special curves specific to their relays.
18.
Their own protective relays, which are designed to protect the line from overload, tripped, isolating Beck Station from all of Southern Ontario.
19.
COMTRADE files are typically generated by Intelligent Electronic Devices ( IEDs ), such as an electronic protective relay, in electrical substations during power systems disturbances.
20.
Maintenance personnel incorrectly set a protective relay on one of the transmission lines between the Sir Adam Beck Station No . 2 in Queenston, Ontario.
