What action does the over-voltage relay perform in the electrical system?

• A. Increases power supply to the engine
• B. Shuts down the electrical line due to voltage spikes
• C. Maintains battery charge levels during flight
• D. Regulates fuel flow in the engine

Answer: (B)

The over-voltage relay is a crucial component in the electrical system of the Beechcraft Travel Air BE-95, as its primary function is to protect the electrical components from damage due to excessive voltage levels. When voltage spikes occur, which can potentially happen in various scenarios such as a malfunctioning alternator or battery issues, the over-voltage relay activates to disrupt the electrical flow. This interruption prevents high voltage from reaching sensitive equipment, thereby safeguarding the integrity of the entire electrical system. Understanding this function emphasizes the importance of voltage regulation in aircraft systems, where reliability and safety are paramount. Proper functioning of the over-voltage relay ensures that the aircraft's electrical components operate within their designed voltage ranges, enhancing overall aircraft reliability during flight.
