Functional Description

IS200RPSAG1A is a Redundant Supply Interface Card developed by GE. It is a part of Mark VI series. It is designed to interface with redundant power supplies, ensuring continuous and reliable power to the control system. It effectively manages the switching between primary and backup power sources to prevent interruptions. The card is designed to integrate seamlessly with other components of the Mark VI control system, ensuring smooth and cohesive operation.

System Power supply features

• Reliable Power Sources: The rack power supplies in the Mark VI control system are supplied power from either a battery, multiple power converters, or a combination of both. This setup ensures that there is always a backup power source available to maintain operation in case one source fails. Redundancy is a key feature, allowing the system to seamlessly switch between power sources without interruption.
• Redundancy and High Select Configuration: Multiple power sources are connected in a high select configuration within the Power Distribution Module (PDM). This configuration enables the system to select the most reliable power source automatically. In the event of a power source failure or during maintenance, the system switches to an alternative source without affecting operational continuity.
• Floating DC Bus and Resistor Network: To stabilize and distribute power effectively, the Mark VI system uses a floating DC bus created by a balancing resistor network. This network utilizes a single ground connection and divides the 125 V DC supply to produce +62.5 V DC (P125) and -62.5 V DC (N125). These voltage rails supply power to the system racks and terminal boards, ensuring consistent and stable operation of control components.
• Ground Fault Detection and Tolerance: The Power Distribution Module (PDM) incorporates ground fault detection mechanisms to monitor the system for any ground faults. Despite its robust design, the system is tolerant of a single ground fault, meaning it can continue operating without performance degradation or blowing fuses. However, the detection of a ground fault triggers an alarm, alerting operators to the issue so that timely repairs can be made.

Frequently Asked Questions

What is IS200RPSAG1A?
It is a Redundant Supply Interface Card developed by GE under the Mark VI series.

What happens if a ground fault occurs in the system?
The system includes ground fault detection mechanisms. It can tolerate a single ground fault without performance degradation or blowing fuses but alarms to alert operators for prompt maintenance.

How does the system manage multiple power sources?
Multiple power sources are managed through a high select configuration in the PDM, which automatically selects the most reliable source. This setup minimizes downtime and ensures continuous operation.

What are the benefits of using a resistor network in the power distribution?
The resistor network stabilizes and distributes power effectively across the system, enhancing reliability and performance in industrial and power generation applications.
