Features:

  • Primary Speed Signal Processing and Overspeed Protective Safeguards
  • Direct Integration for Automatic Generator Synchronization and Main Breaker Management
  • Comprehensive Monitoring for Shaft Electrical Stress and Flame Detection Systems
The General Electric IS200VTURH1BAA functions as the turbine specific primary trip board within a Mark VI Speedtronic control rack, delivering continuous protective oversight and signal processing for turbine operations. It directly processes inputs from four passive pulse rate speed sensors to calculate turbine rotational velocity and relay overspeed trip commands to the controller. The IS200VTURH1BAA enhances system safety over legacy trip mechanisms by combining primary overspeed trip logic, automatic generator synchronization controls, and specialized Geiger-Mueller flame sensor management within a unified system architecture.

The IS200VTURH1BAA provides vital protective functions common to the entire turbine safety architecture, serving as a key hardware component that directly dictates the execution of emergency trip sequences. Depending on system topology, one or more IS200VTURH1BAA boards are deployed in the Mark VI VME rack structure, interfacing directly with the TRPG (Primary Trip Terminal Board). The IS200VTURH1BAA connects through designated rack slots to output trip commands to the magnetic relays mounted on the terminal board.

For high-reliability power generation applications, the system utilizes the IS200VTURH1BAA alongside the VPRO emergency trip card to establish a redundant dual-path safety architecture. Beyond standard single-channel (Simplex) operation, the IS200VTURH1BAA in a Triple Modular Redundant (TMR) configuration works with nine TRPG relays across three voting channels. In this arrangement, the safety network continuously evaluates turbine speed and trip inputs; if the IS200VTURH1BAA detects an abnormal overspeed condition or flame loss, it immediately de-energizes the corresponding relays on the TRPG, firing the Electrical Trip Devices (ETD) to trigger an immediate mechanical shutdown.

The IS200VTURH1BAA General Electric Turbine Specific Primary Trip Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Primary Overspeed Protection: Measures turbine shaft speed via 4 passive magnetic pickup (MPU) devices. It acts to instantly trigger a system trip if boundaries are breached.
  • Flame Detection Tracking: Monitors up to 8 Geiger-Mueller flame detectors inside gas turbine chambers. It isolates fuel valves if a flameout condition occurs.
  • Generator Autosynchronization: Evaluates phase and voltage alignment between the grid and generator. It automatically closes the main breaker relays (K25, K25A, K25P).
  • Shaft Voltage Monitoring: Tracks stray currents and ground faults across the main turbine rotor. It flags early mechanical friction or bearing insulation degradation.
  • Ambient Temperature Range: 0°C to 60°C (32°F to 140°F) continuous.
  • Pulse Rate Frequency: 2 Hz to 20 kHz tracking spectrum.
  • Speed Sensing Accuracy: Within ±0.05% of the total reading.

Description
The General Electric IS200VTURH1BAA is a specialized, turbine-specific primary trip board developed by GE as an essential component of the Mark VI control system architecture. This IS200VTURH1BAA board is specifically designed to address critical turbine safety, monitoring, and synchronization challenges within power generation facilities, solving the complex issue of managing multi-faceted protective protocols while preventing catastrophic mechanical failures. 

Serving as a central control hub within the turbine management framework, the IS200VTURH1BAA orchestrates real-time operational safety, continuous speed evaluation, and automated breaker management. By implementing robust primary safeguarding measures, the IS200VTURH1BAA ensures seamless functionality, protects expensive heavy equipment from operational damage, and maintains overall system integrity.

In terms of specific application scenarios, the IS200VTURH1BAA excels at handling primary overspeed protection by interfacing with four passive pulse rate devices to continuously track turbine rotational speed and relay this data to the main controller for rapid emergency tripping. 

Additionally, the IS200VTURH1BAA manages automatic generator synchronization and main circuit breaker closure, facilitating safe and efficient grid connection. In gas turbine environments, the IS200VTURH1BAA oversees eight Geiger-Mueller flame detectors (requiring an external 335 V DC, 0.5 mA power supply) linked to the TRPG terminal board, ensuring early detection and swift mitigation of flame irregularities or failure conditions. Furthermore, the IS200VTURH1BAA actively monitors induced shaft voltage and current, offering critical diagnostic insight into electrical stress and preventing premature bearing degradation caused by shaft arcing.
