Abstract
An improved circuit interruption system for interrupting a primary circuit includes a secondary circuit disposed in a magnetic field generated by current passing through the primary circuit. In response to a threshold change to the charge induced in the secondary circuit, a circuit interrupting device opens the primary circuit.
Claims15
A circuit interruption system for use with a first circuit conveying a current from a power source to a load, the circuit interruption system comprising:
- a second circuit disposed in a magnetic field generated by the current passing through the first circuit, wherein the magnetic field induces an induced voltage in the second circuit;
- and
- a circuit interrupting device configured to open the first circuit in response to a change in the induced voltage caused by a change in the magnetic field.
A system comprising:
- a first circuit for conveying a current from a power source to a load;
- a second circuit comprising a coil disposed in a magnetic field generated by the current passing through the first circuit, wherein the magnetic field induces an induced voltage in the second circuit proximate the coil;
- and
- a circuit interrupting device configured to open the first circuit in response to a change in the induced voltage caused by a change in the magnetic field.
