More Information

Overview Manuals TGEN Interface Measurement Inputs Generator Calculations Relay Output Path

Features:

  • Receives generator and bus potential signals through the TGEN terminal interface.
  • Combines voltage, current, and configurable analog measurement channels.
  • Transfers twelve relay-output commands to a connected TRLY board.
IS200VGENH1B calculates three-phase power, power factor, and frequency from its generator-monitor input set.

Two three-phase potential-transformer groups and three single-phase current-transformer channels feed IS200VGENH1B through TGEN.

IS200VGENH1B adds four analog channels that can accept 4–20 mA, ±5 VDC, or ±10 VDC signals.

The General Electric IS200VGENH1B Generator Monitor Board may be available for purchase and support from Apter Power for installed Mark VI systems.

Terminal-Board Connection

  • Field interface: TGEN terminates the generator-monitor voltage and current signals.
  • Simplex path: One VGEN connection carries the TGEN signal set.
  • TMR path: Three VGEN connections distribute the signals across redundant processors.
  • Board pairing: IS200VGENH1B processes the TGEN terminal-board inputs.

Voltage, Current, and Analog Channels

  • Potential inputs: Two three-phase PT groups represent generator and bus voltages.
  • Current inputs: Three single-phase CT channels carry generator current measurements.
  • Analog inputs: Four channels accept 4–20 mA, ±5 VDC, or ±10 VDC.
  • Channel purpose: The combined inputs supply the generator-monitor calculations.

Computed Electrical Quantities

  • Three-phase power: IS200VGENH1B derives power from the PT and CT input set.
  • Power factor: The board evaluates the phase relationship between voltage and current.
  • Frequency: Generator frequency is calculated from the incoming voltage signals.
  • Protection functions: PLU and EVA processing is available for large steam-turbine configurations.

Command Transfer to TRLY

  • Output count: Twelve relay commands originate from the IS200VGENH1B processing path.
  • Terminal destination: The command set is delivered to a TRLY relay terminal board.
  • Functional separation: Generator measurements remain on VGEN while field relay wiring terminates on TRLY.
  • System path: The relay interface links calculated conditions to external control circuits.
Description
Electrical monitoring in a Mark VI VME rack is handled by General Electric IS200VGENH1B, a generator monitor and trip board paired with TGEN. The board receives generator and bus signals and places the processed values on the VME bus for control calculations.

The principal measurement set for IS200VGENH1B consists of two three-phase potential-transformer inputs and three single-phase current-transformer inputs. These channels are evaluated together to produce three-phase power, power factor, and electrical frequency.

At the TGEN interface, IS200VGENH1B also receives four configurable analog channels for 4–20 mA, ±5 VDC, or ±10 VDC signals. Field test points support phase checks on voltage and current paths, and the conversion path uses a 16-bit A/D converter with 14-bit resolution.

In the documented large steam-turbine arrangement, IS200VGENH1B supplies the Power Load Unbalance and Early Valve Actuation functions and transfers twelve relay commands to a TRLY terminal board. One TGEN-to-VGEN cable supports simplex use, while three separate VGEN connections support TMR operation.
