FUNCTIONAL DESCRIPTION:

IS200PTBAG2A is a Protection Termination Module manufactured and designed by General Electric as part of the Mark V LM Series used in GE Speedtronic Control Systems. The Protection Termination Module (PTBA), located in the core terminates the signals for the core. Input signals for the high and low-pressure shaft speeds, flame detection, generator and bus voltages, and generator currents are landed on the PTBA terminal board and connected to the TCEB board in . The speed signals are also connected to the core. The external trip input signals, generator and bus signals, and generator breaker close signals are read by the PTBA terminal board and then written directly to the Turbine Trip (TCTG) board in the core. Trip output signals and generator breaker close signals from the TCTG board are written to the unit via the PTBA terminal board. The audible alarm (horn) located on the TCEB board is powered using a hardware jumper on the PTBA board.

FEATURES:

• Overcurrent Protection: The PTM monitors current levels and triggers a shutdown if currents exceed predefined thresholds, preventing damage due to excessive loads.

• Overvoltage Protection: It safeguards against voltage spikes or surges by rapidly disconnecting the power supply when voltages exceed safe limits.

• Undervoltage Protection: The module ensures that the system remains operational within specified voltage ranges, initiating protective actions if voltages fall below acceptable levels.

• Short-Circuit Protection: Detects and responds to short circuits promptly to prevent damage to the system or connected devices.

• Thermal Protection: Monitors temperature levels and implements shutdown procedures if temperatures exceed safe operating limits, preventing overheating.

• Reverse Polarity Protection: Safeguards against incorrect polarity connections, protecting the system from potential damage.

• Status Indicators: Provides clear visual or remote indicators to signal the operational status and any triggered protection mechanisms.

• Resettable and Non-Resettable Functions: Incorporates both resettable and non-resettable protection features based on the nature of the fault, allowing for flexibility and safety.

• Fault Logging and Reporting: Records and reports detected faults for diagnostic purposes, aiding in troubleshooting and maintenance.

• Compatibility and Integration: Designed for seamless integration into existing systems with compatibility across various configurations and components.

FREQUENTLY ASKED QUESTIONS:

How does the PTM protect turbines from overcurrent conditions?

The PTM monitors the current flowing through critical components of the turbine system. If the current exceeds safe limits due to faults or overloads, the PTM will trip and disconnect the power supply to prevent damage.

Why is overvoltage protection important in turbine control systems?

Overvoltage protection is vital in turbine control systems to prevent damage caused by voltage spikes or surges, which can occur due to external factors or system malfunctions. The PTM detects these overvoltages and acts quickly to mitigate the risk.

Can the PTM protect against short circuits in turbine systems?

Yes, the PTM includes short-circuit protection to detect and respond promptly to short circuits within the turbine control circuitry. This protection helps prevent catastrophic damage and ensures system integrity.
