DS200PTCTG1B GE Potential and Current Transformer Board

Description:

DS200PTCTG1B is a Potential and Current Transformer Board manufactured and designed by General Electric as part of the EX2000 Series used in Excitation Control Systems. The voltage and current signals from the PTs and CTs are scaled and isolated by the Potential Transformer Current Transformer (PTCT) board. Additionally, it offers auxiliary inputs and outputs for either 4-20 mA current signals or low voltage ( 10 V dc) signals. The JKK ribbon connector is used to connect the isolation transformer secondaries to the TCCB board. Line side voltage is provided by the third set of three-phase PT inputs, which the control uses for an optional voltage matching capability. The PTCT board is the destination for these connections.

Two-phase CT inputs in one set are supported. The regulator needs to phase A and phase C currents. These CTs provide information on the generator line current feedback for the brushless regulator control's regulator, limiters, and metering functions, including the optional Power System Stabilizer (PSS).
The inputs need a secondary CT input of no less than 5 A. Software modifications are provided for secondary inputs as low as 3 A nominally.
Less than 1 VA is required for each step of the CT. The PTCT board is the destination for these connections.
