Abstract: An apparatus includes an upstream/downstream probability module that determines, for each measurement point in an electrical power system, an upstream/downstream probability. The apparatus includes a zone module that identifies a plurality of zones within the power system and an upstream/downstream module that identifies, for each measurement point and for each zone, if a power quality event in a zone is upstream or downstream of a measurement point. The apparatus includes a zone probability module that determines a zone probability for each zone by multiplying the upstream probability or the downstream probability for each measurement point. The zone probability is a probability that the event happened in a zone. The zone probability module uses the upstream probability of a measurement point when the zone is upstream of the measurement point and uses the downstream probability when the zone is downstream of the measurement point.

Abstract: A method for determining contact thickness change in a contactor includes sensing a first displacement distance moved by an armature of the contactor from a reference location to a first transition point during a switch-off operation of the contactor at a first contactor life reference time when movable contacts and fixed contacts of the contactor define a first contact thickness. The method further includes sensing a second displacement distance moved by the armature from the reference location to a second transition point during a switch-off operation at a second contactor life reference time that is after the first contactor life reference time when the movable and fixed contacts define a second contact thickness that is less than the first contact thickness. The first displacement distance and the second displacement distance are used to determine a contact thickness change between the first contact thickness and the second contact thickness. A contactor adapted to implement the method is also disclosed.

Abstract: Various embodiments of the present technology generally relate to power topology discovery in industrial environments. More specifically, some embodiments relate to automatic power topology discovery for factories based on device data that is already recorded for other purposes. Systems and methods described herein may be used to generate an accurate electrical network topology by collecting power data from power devices that may provide real-time or recorded measurements, detecting power change events, and matching power change signatures over power events for the devices in order to calculate the likelihoods of possible topology assumptions. Power change event data is used to recursively update topology probabilities using the Bayesian formula until a system topology can be produced with satisfactory confidence.

Abstract: For device configuration and monitoring, a processor receives configuration settings from an electronic device via the electronic device interface. The processor converts the configuration settings to hardware settings for a target device. The processor communicates the hardware settings to the target device via a target device interface.
