FUNCTIONAL DESCRIPTION:
IS200TGENH1AAA is a Generator Monitor Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Gas Turbine Control Control Systems. The generator board VGEN and its terminal board TGEN monitor the generator's three-phase voltage and currents and calculate the three-phase power and power factor. For large steam turbine applications, VGEN provides the power load unbalance (PLU) and early valve actuation (EVA) functions, using fast-acting solenoids located on the TRLY terminal board. The VGEN processor works with TGENH1A. Simplex and TMR systems are supported. One TGEN can be connected to the VGEN. With TMR systems, TGEN is cabled to three VGEN boards.
INSTALLATION:
The analog current and potential transformer (PT) inputs are wired to terminal block 1. The current transformer (CT) is wired to special terminal blocks TB2, 3, and 4, which cannot be unplugged. This protects against an open CT circuit. Jumpers J1A and B set the desired input current or voltage on analog inputs 1 through 4.
OPERATION:
VGEN monitors two, 3-phase PT inputs, and three, one-phase current transformer CT inputs. On TGEN four analog inputs can be configured for 4-20 mA or ±5, ±10 V dc. Test points on the generator and bus voltages and currents are for checking the phase of the input signals. Signal conversion and calculations of power, power factor, and frequency take place on the VGEN board.
Test points are provided for all PT and CT inputs to verify the phase in the field. Three single-phase CT inputs are provided with a normal current range of 0 to 5 A continuous. The CTs are magnetically isolated on TGEN. Terminations for the CTs are non-pluggable terminal blocks with captive lugs accepting up to #10 AWG wires. The four analog inputs can accept 4-20 mA inputs or ± 5, ± 10 V dc inputs. A +24 V dc source is available for all four circuits with individual current limits for each circuit. The 4-20 mA transducer can be connected to use the +24 V dc source from the turbine control or as a self-powered source.
