| 11. | In three phase power transmission applications, autotransformers have the limitations of not suppressing ground fault currents.
|
| 12. | A circuit breaker ( within a switchgear enclosure ) is the primary component that interrupts fault currents.
|
| 13. | This is similar to a control relay but requires a rather high fault current to operate the contacts.
|
| 14. | The combination of equipment within the switchgear enclosure allows them to interrupt fault currents of thousands of amps.
|
| 15. | A high-resistance-grounded system may restrict line to ground fault current to only 5 amperes.
|
| 16. | The ELCB detects fault currents from live to the Earth ( ground ) wire within the installation it protects.
|
| 17. | A fault current quenches the superconductor, the secondary becomes resistive and the inductance of the whole device rises.
|
| 18. | Inductors are also employed in electrical transmission systems, where they are used to limit switching currents and fault currents.
|
| 19. | When a large fault current flows through the circuit breaker, this is detected through the use of current transformers.
|
| 20. | Almost any fault would instead be a single-phase earth fault which does not produce a large fault current.
