  • Patent number: 8853586
    Abstract: An electrical switching apparatus includes two arc runners, two contacts in electrical communication with the respective runners, a movable contact having two portions respectively cooperating with the contacts to provide closed and open contact positions, and two arc chambers each including two ends, a longitudinal axis therebetween, and arc plates between the ends. A magnet assembly cooperates with the arc chambers to establish a generally unidirectional magnetic field normal to the axes, normal to a first direction of a first arc between one contact and the first portion as it moves away from the closed toward the open contact position, and normal to an opposite second direction of a second arc between the other contact and the second portion as it moves away from the closed toward the open contact position. The magnetic field causes one arc to enter one arc chamber depending upon current flow direction between the contacts.

  • Patent number: 8638531
    Abstract: A hybrid DC contactor includes contacts that provide a first current path between a DC power source and a load, an electromagnetic coil to position the contacts, a semiconductor switch in parallel with contacts that, when turned on, provides a second parallel current path that diverts current away from the contacts when the main contacts are being opened in either direction. A controller is provided to terminate power to the electromagnetic coil to open the contacts, detect an arc voltage across the contacts as the contacts open, provide a gate signal to the semiconductor switch to pulse the switch on for a pre-determined period of time to route current to the semiconductor switch, measure a current through the contacts and, if current is present through the contacts, then provide another gate signal to the semiconductor switch to pulse the switch on again so as to route current thereto.

  • Patent number: 8368492
    Abstract: A direct current electrical switching apparatus includes a first contact in electrical communication with first and third arc runners, a second contact in electrical communication with second and fourth arc runners, a movable contact, a first arc chamber including first arc plates having a first width, a second arc chamber including second arc plates having a greater second width, an operating mechanism, and a magnet assembly cooperating with the arc chambers to establish generally oppositely directed magnetic fields. The magnetic fields cause one of a first arc and a second arc to enter one of the arc chambers depending upon a direction of current flow between the contacts. The electrical switching apparatus is rated for a first magnitude of current flowing from the first contact to the second contact and for a greater second magnitude of opposite second current flowing from the second contact to the first contact.

  • Patent number: 7777516
    Abstract: A system and method for detecting incipient mechanical motor faults by way of current noise cancellation is disclosed. The system includes a controller configured to detect indicia of incipient mechanical motor faults. The controller further includes a processor programmed to receive a baseline set of current data from an operating motor and define a noise component in the baseline set of current data. The processor is also programmed to repeatedly receive real-time operating current data from the operating motor and remove the noise component from the operating current data in real-time to isolate any fault components present in the operating current data. The processor is then programmed to generate a fault index for the operating current data based on any isolated fault components.

  • Publication number: 20080151761
    Abstract: An embedded system includes a first wireless node and a number of second wireless nodes, each of which includes a wireless transceiver, a memory storing a schedule defining transmission and reception of test packets, and a processor transmitting and receiving the test packets responsive to the schedule. The memories store a corresponding predetermined application employing some of the wireless communications, and a corresponding predetermined measurement function measuring wireless communication performance. A corresponding one of the schedules is executed by the corresponding predetermined measurement function. The second wireless nodes wait to receive a number of the test packets before being synchronized with their schedule and receiving and transmitting the test packets according to their schedule. The processors store data from the test packets to assess wireless communication performance between corresponding nodes.
