Abstract: An electrical connector having an electrical conductor member with a first opening and a second opening. Grab rings mounted in the openings have inner diameters containing teeth with crests defining a superimposed inner diameter. The teeth of the grab rings deflect and frictionally engage the outer diameter of the wires to retain them in the openings. A sleeve of insulation material covers an exterior of the conductor member. The sleeve has ends that protrude past the openings and receive an insulation layer of the wires. Resilient electrical contact members are recessed from the grab rings in the openings. The electrical contact members have inner portions biased into contact with the electrical wires and outer portions biased into contact with the conductor member.

Abstract: A subsea pump assembly includes a tubular conduit that has an upstream end plate and an inlet for flowing well fluid into an interior of the conduit. A power cable opening extends through the upstream end plate. An electrical submersible pump and motor are in the interior of the conduit. The motor has a motor assembly housing with an upstream end having an electrical insulator opening. An end connection secures the upstream end to an interior side of the upstream end plate with the insulator opening registering with the power cable opening. An insulated electrical connector is mounted in the insulator opening. A motor wire in the motor assembly housing joins to an inner end of the electrical connector. A power conductor extends from exterior of the conduit through the power cable opening and joins to an outer end of the electrical connector.

Abstract: Systems and methods for constructing electric motors in which rotor sections are individually keyed to a rotor shaft such that, in a resting position, the rotor sections are circumferentially shifted (“clocked”) with respect to each to mitigate effects of harmonic feedback, torsional flexibility and the like. In one embodiment, a system includes an electric drive, and an ESP coupled to it by a power cable. The ESP motor has a rotor in which multiple permanent-magnet rotor sections are mounted to a shaft. Within each rotor section, permanent magnets are positioned in two or more axially aligned rows. Adjacent rotor sections are clocked with respect to each other so that, in operation, the rows of permanent magnets in the different rotor sections are positioned to counter the harmonic feedback or to use torsional deflection to equalize torque contributions from the different rotor sections.

Abstract: An electronic representation of a network and at least one equipment at the network is received. Intelligent electronic device (IED) information describing at least one IED is received. The at least one IED has an associated plurality of logical IED nodes. A map is created that associates the at least one equipment to an instance of a selected one of the plurality of logical IED nodes. A configuration interface is created and is based upon at least one of the electronic representation of the network, the IED information, and the map. The IED information and the configuration interface are generated automatically.

Abstract: A submersible well pump motor has features to prevent the carrier bearing from sliding axially along the stator due to thermal growth of the rotor. The rotor has a shaft and rotor sections spaced apart from each other. Carrier bearings are located between the rotor sections, each having an anti-rotation member that frictionally engages the inner diameter of the stator to prevent spinning of the carrier bearing. A deflectable thrust washer may be located between ends of the carrier bearing and the rotor sections. The thrust washer reduces in thickness in response to an axial thermal growth force due to axial thermal growth movement of the rotor sections and shaft. The thermal growth force is less than an amount of dislodging force required to cause the anti-rotation member to axially move relative to the stator. Rather than deflectable thrust washers, sacrificial thrust washers that dissolve prior to normal operation may be used.

Abstract: A thrust module and a seal module for use in an electric submersible pump assembly is provided. The thrust module provides increased lubrication and heat dissipation while increasing sealing redundancies within the module. The thrust module includes a thrust bearing that absorbs thrust from the primary pump. A circulation pump assembly is coupled to the thrust bearing to circulate fluid through the thrust bearing and dissipate heat generated in the thrust bearing through a plurality of fins formed on an exterior surface of the circulation pump assembly. The seal module has labyrinth discs positioned within the seal module that inhibit fluid flow through the seal module. The seal module also includes check valves that release fluid from and allow fluid into the seal module at predetermined pressures. The sealing assembly is interposed between the thrust bearing and a primary pump of the electric submersible pump.
