Specify Schneider Electric P3G32-CGI1A-KA1NA-BAAAA for Generator Protection, Machine Differential Protection and Event Recording

Schneider Electric P3G32-CGI1A-KA1NA-BAAAA is a configured PowerLogic P3G32 protection relay for generator applications requiring machine differential protection. It combines protection, measurement, control, supervision and disturbance-recording functions in one relay platform for medium-voltage generation systems.

Protection functions for generator applications

• Machine differential protection for internal generator faults.

• Under-impedance, overcurrent and earth-fault protection functions.

• Overvoltage, undervoltage, frequency and power-related protection.

• Synchro-check, trip-circuit supervision and circuit-breaker monitoring.

• Sequence-of-events, disturbance and tripping-context records for fault analysis.

Integrate protection, control and communication carefully

The P3G32 platform supports configurable digital and analog I/O, programmable logic and communication options. The exact supply voltage, I/O cards, communication protocol, mounting arrangement and arc-flash options depend on the complete order code, so the approved protection schematic and relay configuration file should be reviewed before replacement.

Ordering and commissioning checklist

• Use the full code P3G32-CGI1A-KA1NA-BAAAA on the quotation.

• Confirm CT and VT ratios, phase rotation, differential-zone polarity and grounding method.

• Verify auxiliary supply, binary I/O, trip outputs and communication interfaces.

• Load the approved settings only after checking the protection study and logic diagrams.

• Perform secondary injection, trip-circuit and end-to-end functional tests before service.
