  • Page 16: Rectifier Designs

    Overview of Drive Rectifier Designs Active Front-End (AFE) Rectifier An Active Front-End rectifier is particularly attractive since it does not require an isolation transformer to meet IEEE 519-1992. Many competing technologies in today’s MV market require a multi- winding transformer to mitigate the unwanted harmonics through cancellation by phase shifting the transformer secondary windings.
  • Page 17: Direct-To-Drive" Technology

    “Direct-to-Drive” Technology Reduce the cost, size and weight of your medium voltage drive system with the Allen-Bradley PowerFlex 7000 with Direct-to-Drive technology. This is the first and only technology that allows you to directly connect a medium voltage drive to utility power without the requirement of an isolation transformer.
  • Page 18: Motor Compatibility

    Overview of Drive Motor Compatibility The PowerFlex 7000 achieves near sinusoidal current and voltage waveforms to the motor, resulting in no significant additional heating or insulation stress. Temperature rise in the motor connected to the VFD is typically 3 °C (5.4 °F) higher compared to across-the-line operation.

    Component Definition and Maintenance 4-53 Optical Interface Boards The Optical Interface (OIB) Boards are the interface between the DPM and the Gate Driver circuitry. The drive control decides which device to fire, and sends an electrical signal to the OIB boards. The OIB board converts that electrical signal to an optical signal, which is transmitted via fiber optics to the gate driver cards.

  • Page 199: Appendix D Meggering

    Appendix Meggering Drive Meggering When a ground fault occurs, there are three zones in which the problem may appear: input to the drive, the drive, output to the motor. The ground fault condition indicates a phase conductor has found a path to ground. Depending on the resistance of the path to ground, a current with magnitude ranging from leakage to fault level exists.
  • Page 200: Equipment Required

    Meggering There exists the possibility of serious or fatal A T T E N T I O N A T T E N T I O N injury to personnel if safety guidelines are not followed. The following procedure details how the Megger test on the PowerFlex 7000A is to be performed.
  • Page 201 Meggering Note: It is important to disconnect the terminals on the boards rather than from the ground bus as the grounding cable is only rated for 600 V. Injecting a high voltage on the ground cable will degrade the cable insulation. Do not disconnect the white medium voltage wires from the VSBs.
  • Page 202 Meggering Potential Transformer Fuses A Megger test may exceed the rating of potential transformer fusing. Removing the primary fuses from all potential and control power transformers in the system will not only protect them from damage but remove a path from the power circuit back to the drive control.
  • Page 203 Meggering The test should produce a reading greater than the minimum values listed below. If the test results produced a value lower than these values start segmenting the drive system down into smaller components and repeat the test on each segment to identify the source of the ground fault.
  • Page 204 Meggering 6. Reconnect the Power Circuit to the System Ground Voltage Sensing Boards Securely reconnect the two ground conductors on the VSBs. The two ground connections on the VSB provide a reference point for the VSB and enable the low voltage signal to be fed to the SCBs.
