GE T35-W00-HKH-F8M-H6V-M8M-P6V-U6V-W6V Protective Relay Modules

Configured for high-speed differential protection in electrical substation networks, the GE T35-W00-HKH-F8M-H6V-M8M-P6V-U6V-W6V (T35-W00-HKH-F8M-H6V-M8M-P6V-U6V-W6V Transformer Protection System) provides direct physical/electrical execution. It processes electrical currents from up to six sets of current transformers (CTs) to execute phase and ground overcurrent logic profiles natively at the substation tier to maintain differential trip execution parallel to master control network platforms.

Hardware Specifications

Industrial Control & Drive Integration

• Backplane Bus Communication Velocity Licences and Firmware Compatibility: The hardware platform utilizes a high-priority internal bus to align multi-channel current input sampling cycles, enforcing strict firmware flash compatibility across safety-critical automation states.
• Profinet / EtherNet/IP Deterministic Networks Mapping: Real-time protection tasks run independently from external network communication interfaces, ensuring that wide-area data delivery over Routable GOOSE (R-GOOSE) or local process bus execution routines do not introduce processing delays or jitter to the core transformer differential trip circuits.
• I/O Density Scaling: High-density digital input and output module options support flexible field wiring structures while preserving internal signal isolation barriers.

Frequently Asked Questions

Q: Can the internal high-density I/O modules be swapped out while the protection system is energized?

A: No. The internal backplane power architecture is not designed for hot-swapping. Control power must be completely disconnected from the unit before removing or installing internal modular cards to prevent electrical transients or unstable logical output states.

Q: How are concurrent measurements from the 6 sets of CT inputs reconciled within the processing loops?

A: The digital processing block samples all 6 current transformer inputs synchronously. The internal clock structure maintains determinism across the input matrices, computing differential equations and phase balances within a single processing sub-cycle.

Field Installation Guidelines

• Mechanical Mounting: Secure the rack-mount chassis firmly into standard 19-inch electrical cabinets using appropriate structural fasteners to withstand substation seismic and operational vibrations.
• Shielded Grounding: Ensure all process bus fiber-optic lines and secondary CT circuit shield drains are properly terminated to the designated substation earth grounding bus to prevent electromagnetic interference.
• Terminal Torque Specification: Fasten all current and voltage terminal screws using calibrated torque drivers to standard industrial ratings to maintain secure electrical continuity under high fault current conditions.
