| 1. | The Aurora vulnerability is caused by the out-of-sync closing of the protective relays.
|
| 2. | Protective relays can also be classified by the type of measurement they make.
|
| 3. | Behind the driver is case inside of which has an electric panel protective relays.
|
| 4. | His work soon broadened to include transmission lines, distribution systems, and protective relays and switches.
|
| 5. | A protective relay may respond to the magnitude of a quantity such as voltage or current.
|
| 6. | A protective relay detects any imbalance in currents, and trips circuit breakers to isolate the device.
|
| 7. | Systems for process control and protective relays used analog computation to perform control and protective functions.
|
| 8. | Correct identification of terminals and wiring is essential for proper operation of metering and protective relay instrumentation.
|
| 9. | Digital protective relays are primarily IEDs, using a microprocessor to perform several protective, control and similar functions.
|
| 10. | In 1975, a 14-car Tait train ran between the Royal Park substations, to test a new protective relay device.
