Abstract
Various embodiments disclosed herein provide techniques for detecting electrical arcing in an electrical system. The techniques include a network device receiving first voltage or current readings associated with a first power cycle, receiving second voltage or current readings associated with a second power cycle, determining that an electrical arcing condition is present by comparing the first voltage or current readings with the second voltage or current readings, and performing a remedial operation in response to determining that the electrical arcing condition is present.
Claims19
A method comprising:
- receiving, by a network device, first voltage or current readings associated with a first power cycle;
- receiving, by the network device, second voltage or current readings associated with a second power cycle;
- determining, by the network device, in response to a slope of a trend model determined from the first voltage or current readings and the second voltage or current readings being above a threshold, that an electrical arcing condition is occurring;
- and
- performing, by the network device, a remedial operation in response to determining that the electrical arcing condition is present.
One or more non-transitory computer-readable media storing program instructions that, when executed by one or more processors, causes the one or more processors to perform operations comprising:
- receiving first voltage or current values measured on an electrical circuit during a first power cycle;
- receiving second voltage or current values measured on the electrical circuit during a second power cycle;
- determining, in response to a slope of a trend model determined from the first voltage or current readings and the second voltage or current readings being above a threshold, that an electrical arcing condition is occurring in the electrical circuit;
- and
- performing one or more remedial actions in response to determining that the electrical arcing is occurring in the electrical circuit.
A utility monitoring device, comprising:
- one or more processors, and
- a memory storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
- receiving first voltage or current measurements for an electrical circuit during a first power cycle;
- receiving second voltage or current measurements for the electrical circuit during a second power cycle;
- determining, in response to a slope of a trend model determined from the first voltage or current measurements and the second voltage or current measurements being above a threshold, that electrical arcing is occurring in the electrical circuit;
- and
- performing a remedial action in response to determining that there is electrical arcing in the electrical circuit.
