Abstract
In a protection apparatus capable of protecting a equipment from an electromagnetic pulse and a control method thereof, the apparatus includes a switching unit configured to electrically connect or disconnect a power line to or from the equipment, a sensing unit configured to detect a current flowing on the power line at a reference time interval, and a controller configured to control the switching unit according to a pulse width of the detected current.
Claims23
A protection apparatus for protecting a equipment from an electromagnetic pulse flowing on a power line, the apparatus comprising:
- a switching unit configured to electrically connect or disconnect the power line to or from the equipment;
- a sensing unit configured to detect a current flowing on the power line at a reference time interval;
- and
- a controller configured to control the switching unit according to a pulse width of the detected current.
A control method for a protection apparatus for protecting a equipment from an electromagnetic pulse flowing on a power line, the method comprising:
- detecting a current flowing on the power line at a reference time interval;
- determining whether or not the detected current contains an electromagnetic pulse having a pulse width more than a preset time;
- and
- controlling a switching unit to electrically connect the power line to the equipment according to the determination result.
