As proven, the MLEs 500 connect to a motor block 315, which could also be a motor (or motors) of a pump (e.g., an ESP, and many others.) and be controllable by way of the VSD/step-up transformer block 370. In the instance of FIG. 3, the conductors of the MLEs 500 electrically join at a WYE level 325. The circuitry block 350 could derive power by way of the WYE point 325 and may optionally transmit, receive or transmit and obtain knowledge via the WYE point 325. As shown, the circuitry block 350 may be grounded. For a LVD, a VSD unit can embody a step-up transformer, management circuitry and a step-up transformer whereas, for a MVD, a VSD unit can include an integrated transformer and control circuitry. The VSD unit 270 could include commercially available control circuitry such as the SPEEDSTAR™ MVD control circuitry marketed by Schlumberger Limited (Houston, Tex.). The SPEEDSTAR™ MVD management circuitry can optionally interface with the UNICONN™ motor controller, which can present some of the foregoing functionality. The UNICONN™ motor controller can embrace management functionality for VSD units equivalent to target speed, minimum and maximum pace and base velocity (voltage divided by frequency); three bounce frequencies and bandwidths; volts per hertz sample and begin-up boost; potential to start out an ESP while the motor is spinning; acceleration and deceleration charges, together with start to minimum speed and minimal to focus on pace to maintain fixed stress/load (e.g., from about 0.01 Hz/10,000 s to about 1 Hz/s); cease mode with PWM provider frequency; base velocity voltage selection; rocking start frequency, cycle and pattern control; stall safety with automated speed reduction; changing motor rotation route without stopping; velocity power; pace follower mode; frequency control to take care of constant velocity, pressure or load; current unbalance; voltage unbalance; overvoltage and undervoltage; ESP backspin; and leg-ground.

For FSD controllers, the UNICONN™ motor controller can monitor ESP system three-phase currents, three-phase floor voltage, supply voltage and frequency, ESP spinning frequency and leg ground, energy issue and motor load. For instance, a power cable for use with an electric submersible pumping system can include a conductor; an insulation layer disposed on an outer floor of the conductor; a barrier layer disposed on an outer floor of the insulation layer; and a protecting layer disposed on an outer surface of the barrier layer. For instance, an ESP could embody a hydraulic diaphragm electric submersible pump (HDESP), which is a positive-displacement, double-performing diaphragm pump with a downhole motor. For example, a motor could embrace windings, and so on., for three or more phases. As an example, a flat kind issue cable could also be used in low clearance functions within a bore or, for example, in shorter run lengths where a rise in temperature of a center conductor shouldn't be an appreciable concern during operation.

Extruded XLPE might are likely to have a low crosslink density, as such, the XLPE may exhibit low chemical compatibility compared to completely cured XLPE (e.g., more extremely crosslinked XLPE). In the instance of FIG. 2, the VSD unit 270 could also be a low voltage drive (LVD) unit, a medium voltage drive (MVD) unit or different sort of unit (e.g., a excessive voltage drive, which may present a voltage in excess of about 4.16 kV). The SPEEDSTAR™ MVD management circuitry is suitable for indoor or out of doors use and comes commonplace with a visible fused disconnect swap, precharge circuitry, and sine wave output filter (e.g., integral sine wave filter, ISWF) tailored for control and protection of excessive-horsepower ESPs. The SPEEDSTAR™ MVD management circuitry can include a plug-and-play sine wave output filter, a multilevel PWM inverter output, a 0.95 energy issue, programmable load discount (e.g., comfortable-stall operate), speed control circuitry to maintain constant load or stress, rocking begin (e.g., for stuck pumps ensuing from scale, sand, and so forth.), a utility energy receptacle, an acquisition system for the PHOENIX™ monitoring system, a site communication box to assist surveillance and management service, a speed control potentiometer. For instance, a REDA™ HOTLINE™ excessive-temperature ESP motor may be implemented in a thermal recovery heavy oil production system, comparable to, for example, SAGD system or other steam-flooding system.

In the instance of FIG. 2, the motor controller 250 contains numerous options to handle, for instance, backspin of an ESP, sanding of an ESP, flux of an ESP and gasoline lock of an ESP. FIG. 19 shows a plot 1900 for knowledge from a second heating run for pure PP, uncured pure XLPE, and uncured blends of XLPE/PP 75/25 and XLPE/PP 50/50 wt %. For instance, the UNICONN™ motor controller can interface with the PHOENIX™ monitoring system, for example, to entry strain, temperature and vibration information and various safety parameters as well as to provide direct present power to downhole sensors. For connection to a energy cable or motor lead extensions (MLEs), a motor might embody a pothead. Over time, creep can happen and failure of a number of of the protecting lead (Pb) walls between conductors. Further monitoring of power high quality from a provide, to a motor, at a motor, might occur by one or more circuits or options of a controller.
