What happens to the ESS buses if a short is detected?

When a short is detected in the Electrical Supplementary System (ESS) buses of the Dassault Falcon 7X, the system is designed to automatically untie those buses. This untying is a safety feature that isolates the affected circuits to prevent further damage to the electrical system and to maintain overall safety and functionality of the aircraft.

This automatic action allows the aircraft to maintain power to other essential systems that are not affected by the short circuit, thereby ensuring that critical operations can continue. The system’s design is focused on minimizing risk during potential electrical faults, making the automatic response essential for safe operations.

Remaining connected for safety or completely turning off would not facilitate the functioning and safety of other systems that may still be operational. Additionally, requiring manual intervention would result in delays that could be hazardous in certain circumstances. Therefore, the automatic untying of the ESS buses is a crucial feature in maintaining the integrity of the aircraft's electrical systems during anomalies like a short circuit.
