摘要： Provided is a plug for use as a disconnector for current transformers. Two types of short circuits are provided in the plug. A first short circuit is used for diverting overvoltages by short-circuiting the electrical contacts in the plug. A second short circuit is provided for short-circuiting electrical contacts in the plug when the plug is not contacted. The short circuits are designed in such a way that the first short circuit is used as a fuse when the second short circuit fails.

摘要： The disclosure relates to a method, apparatus and computer readable medium for compensating for capacitive coupling effects in an inductive current sensor. The method comprises receiving a current of an electrical signal measured at a current sensor at an instant in time. The method further comprises applying a capacitive coupling compensation coefficient to a voltage of the electrical signal measured at a voltage sensor at the instant in time to obtain a capacitive coupling compensation value. Furthermore, the method comprises adjusting the current of the electrical signal using the capacitive coupling compensation value to obtain a compensated current of the electrical signal.

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.

摘要： An inductor design having a detection winding which is magnetically coupled to the existing winding and its induction voltage is used to cancel that of the existing winding. Having the induction voltage cancelled, the voltage across the existing winding represents a resistive voltage drop of the existing winding current. The detection winding is furthermore built with a non-inductive portion having a significantly higher DC resistance in proportion to that of the existing winding. This resistance proportion is insensitive against temperature variations when both the existing and the detection windings are built with the same material and subjected to the same environment. A reference current is fed through the detection winding to produce a reference resistive voltage drop which is used to cancel the resistive voltage drop across the existing winding. When a precise cancellation occurs, the existing winding current is known to be in exact proportion to the reference current.
