GE F3500HCHF8FH6GM8FP6HCXXWXX Multiple Feeder Protection Module

Configured for multi-circuit protection and variable distance tracking in electrical substations, the GE Fanuc Multilin F35E00HCHF8FH6GM8FP6HUXXWXX (F35 Multiple Feeder Protection Module) provides direct physical execution of programmatic tripping arrays across distribution network platforms.

Hardware Specifications

Industrial Control and Networks

• Backplane Bus Communication Velocity: The hardware platform routes raw digital samples from the analog card slots across a high-speed parallel internal bus structure. This framework ensures that calculated distance protection matrices update in real time, executing fault clearance triggers within fixed millisecond clock intervals to maximize power line stability.
• I/O Density Scaling: The modular frame accepts distinct input topologies including completely independent current/voltage paths, independent current/common voltage arrays, or dedicated current-only links. This variable density packs multiple distinct feeder protection sectors into a unified 4U chassis, dropping external hardware count.
• Firmware Flash Compatibility: Core tripping equations, reclosing logic maps, and network protocol dictionaries reside in non-volatile flash sectors. The hardware firmware version must correlate exactly with the active engineering software platform build to prevent operational configuration blocks during runtime modifications.

Frequently Asked Questions

Q: How does the auto-reclosure element manage the independent dead time timing parameters across multi-shot sequences?

A: The firmware allows up to 4 consecutive reclose attempts, with each individual shot mapped to an independent, software-adjustable dead time register. When a distance zone trips the breaker, the reclose state machine loads the specific delay vector for that step, waiting out the programmed de-energization period before pulsing the breaker close coil.

Q: What action takes place within the distance tracking blocks if a hardware fault causes an unexpected dropout condition?

A: The internal processing core runs continuous runtime self-diagnostics. If the signal falls below the 97–98% dropout zone or if an internal hardware tracking error occurs, the module immediately forces a critical device alarm, blocks the active distance zone tripping circuits to prevent spurious operations, and flags a diagnostic error across the substation automation network.
