SURGE CURRENT SENSOR AND SURGE PROTECTION SYSTEM INCLUDING THE SAME

摘要

The present invention may provide a surge current sensor and a surge protection system that deploys one or more surge current sensors. The surge current sensor may be placed on or near to a conduit, and it may be used for sensing the surge current conducted therein. The surge current sensor may include a current transformer and a processor. The current transformer may be used for receiving a magnetic flux generated by the surge current and transforming the received magnetic flux to a voltage. The processor may be coupled with the current transformer, such that it may be configured to generate a digital signal based on the voltage. Once the digital signal indicates that the magnitude of the surge current has exceeded a predefined threshold, the surge protection system may initiate a surge protection mechanism.
