FUNCTIONAL DESCRIPTION:

IS200CPFXG1A is a Phase Leg Flash Protection Board manufactured and designed by General Electric as part of the Drive Control Series used in GE Drive Control Systems. The main purpose of the board is to provide power isolation for the IS200PICH Phase Interface and Control Board. Each phase leg is equipped with a single CPFX board, and there is one IS200 Control Power Flash Protection Board per bridge. Multiple outputs from the Control Power Flash Protection Board are linked to each Phase Leg Flash Protection Board. When the CPFX board operates in conjunction with the PICH board, it effectively isolates the power of an individual phase leg from the other phase legs. The Phase Leg Flash Protection Board (CPFX) lacks LED indicators, test points, fuses, or user-adjustable hardware. It features two plug connectors and flying leads connecting the transformer to the CPFX board. Moreover, it establishes connections with both the CPFP board and the PICH board.

FEATURES:

• Two plug connectors for enhanced connectivity.
• Flying leads facilitate the connection between the transformer and the CPFX board.
• Does not include LED indicators, test points, fuses, or user-adjustable hardware.
• Establish connections with both the CPFP board and the PICH board.

INSTALLATION:

The board is mounted securely onto the DIN-rail, aligning it precisely with the rack architecture to maintain mechanical stability and proper clearance for wiring. Electrical interfacing is performed by connecting the dual plug connectors (J1 and J2) to the CPFP and PICH boards, while flying leads are routed to the control transformer. Proper cable management is critical to separate high-voltage lines from low-voltage control signals, and all terminal screws and connectors are tightened to the manufacturer-specified torque values to ensure low-impedance connections and minimize electromagnetic interference (EMI). Once installed, the system undergoes visual inspection, continuity checks, and insulation resistance verification to confirm proper electrical integrity. With its surface-mount components and pre-configured circuitry, the board requires no field adjustments or jumpers and is immediately ready to provide high-speed phase leg isolation, detecting voltage transients, flashovers, and faults to protect the drive system reliably.

OPERATION:

It detects abnormal voltage conditions, such as transients, surges, or potential phase-to-phase flashovers, using its integrated sensing circuitry. When a fault is identified, the board�s internal isolation logic acts rapidly to disconnect the affected phase leg from the system, preventing the fault from propagating to other phase legs or downstream equipment. The board interfaces directly with the CPFP (Control Power Flash Protection) board and PICH (Phase Interface and Control) board, coordinating the distribution of protective signals and ensuring that only the faulty phase is isolated while maintaining continuous operation of the remaining phases. Because it is fully pre-configured and relies on circuit-level protection mechanisms, no external adjustments or monitoring inputs are needed, enabling fail-safe, high-speed protection that enhances system reliability and reduces downtime.

FREQUENTLY ASKED QUESTIONS:

What is IS200CPFXG1A?

IS200CPFXG1A is a Phase Leg Flash Protection Board from General Electric, designed to provide electrical isolation and fault protection for individual phase legs in GE Drive Control Systems. It monitors voltage transients and short circuits, isolating faulty phases to protect the system.

What are the main components of a Phase Leg Flash Protection Board?

The main components typically include sensors for detecting electrical abnormalities, a control unit for processing signals and initiating protective actions, and switches or relays for isolating the faulty phase.

How does the IS200CPFXG1A interface with system components?

The board is electrically interfaced via dual plug connectors (J1 and J2) and flying leads, establishing connections with the CPFP (Control Power Flash Protection) board, PICH (Phase Interface and Control) board, and the system control transformer. These connections enable bidirectional signal and power coordination for real-time fault isolation.

How does the board handle multiple simultaneous phase faults?

The board isolates each affected phase leg independently using its internal relay logic. Coordination with the CPFP and PICH boards ensures that only faulty legs are disconnected, allowing unaffected phases to continue normal operation.
