GENERAL ELECTRIC IS200TTURH1BED Protection Input turbine terminal Board

GE  IS200TTURH1BED  Input turbine terminal Board 

Specification

Funcrional  Description 

IS200TTURH1BED is a Protection Input turbine terminal Board developed by GE.

It is a part of the Mark VI control system. It interfaces with the turbine I/O processor

and plays a key role in managing inputs and outputs related to turbine operations

This board is integral for ensuring accurate measurement and control of various turbine parameters.

Inputs and Outputs

The TTUR is connected to twelve passive pulse rate devices. These devices utilize a toothed wheel to measure the turbine’s rotational speed. The pulse signals

generated by these sensors are used to calculate the turbine speed precisely, which is essential for monitoring and controlling turbine performance.

The TTUR handles generator and bus voltage signals, both of which are obtained from potential transformers. These transformers reduce high voltages

to lower, manageable levels, providing accurate voltage readings crucial for the safe and efficient operation of the generator and bus systems.

A 125 V DC output is provided by the TTUR to the main breaker coil. This output is necessary for automatic generator synchronizing. It

enables the main breaker to close and align the generator with the power grid, ensuring seamless integration and operation.

The TTUR receives inputs from shaft voltage and current sensors. These sensors measure the induced voltage and current in

 the turbine’s shaft, which are vital for assessing the turbine’s operational health and ensuring optimal performance.
