electric power system

#1. In an electrical circuit the reverse current cut-out relay will open:

• Awhen battery voltage exceeds generator voltage.
• Bwhen circuit voltage is less than generator voltage.
• Cwhen the main output C/B is reset.
• Dwhen the batteries are flat.

#2. A generator cut-out is provided:

• Ato prevent the battery over heating.
• Bto prevent the battery from being overcharged.
• Cto allow the generator to be isolated in a crash.
• Dto prevent discharge of the battery through the generator.

#3. A generator cut-out will open when:

• Acircuit loads equal the battery voltage.
• Bthe air temperature reaches 45 C.
• Ccircuit loads equal the generator voltage.
• Dgenerator voltage falls below battery voltage.
