The Vector VII Variable Speed Drive is designed specifically for oil-field pumping applications
including electrical submersible pumps (ESP) and surface pumping systems (SPS). Vector VII
drives are available in ratings from 104 KVA to1500 KVA. They are provided in rugged outdoor
rated enclosures designed for a wide variety of environments ranging from arctic to desert
conditions. Application specific software and a GE Oil & Gas Custom Operator Control Panel
combine to optimize pump control while simplifying drive operation.
Vector VII uses the latest Insulated Gate Bipolar Transistor (IGBT) technology in combination
with surface mount printed circuit boards to create a VSD of the highest reliability, and small
physical size. Fixed voltage, three-phase AC input power is first converted to a fixed DC bus
voltage by the input rectifier section of the drive. That fixed DC bus voltage is then processed
by the inverter section to produce a sine coded variable voltage, variable frequency output to
control the speed of the motor.
For ESP applications, the Vector VII Variable Speed Drive is available with integrated VSG®
Technology. With VSG Technology the drive output voltage waveform is a near perfect sinewave which results in improved motor performance, extended motor run life, extended motor
cable life, and increased operational efficiency in the driven equipment. Vector VII drives with
VSG (Variable Sinewave Generation) technology can successfully operate with motor cable
lengths up to 15,000 ft.
User adjustments include operating speed, acceleration and deceleration rates, motor overload
protection settings, auto restarts, time delays, and stopping methods. Control methods include
frequency control, current control, pressure control, or analog follower (Analog 1 = 0-10 VDC,
Analog 2 = 0-10 VDC or 4-20 mA) capability.
