Q

Each engine driven generator can supply up to 90kva of AC power whereas the Emergency generator (blue hydraulic RAT) can supply up to:

A

5kva

2
Q

When a monitored (— —-) circuit breaker is out for more than 1 minute an ECAM warning C/B TRIPPED is triggered.

A

Green

3
Q

GEN 1 and 2 when operating have priority over the APU generator and external power. T or F

A

True

4
Q

External power has priority over the APU generator when the EXT PWR pb switch is on. T or F?

A

True

5
Q

When they are fully charged the Battery Charge Limiter disconnects the ——— from the DC BAT BUS.

A

Batteries

6
Q

The system automatically replaces the failed generator with the:

A

APU generator if available, or the other engine generator.

7
Q

Part of the Galley load is shed during:

A

Single generator operations

8
Q

During Emergency Generation after loss of all main generators, below 125kt the emergency generator is

A

No longer powered. The emergency generation network is automatically transferred to the batteries and AC SHED ESS and DC SHED ESS BUS are shed.

9
Q

During RAT extension and emergency power coupling (— seconds) the ———— power the emergency generation network.

A

8 seconds

Batteries

10
Q

The smoke configuration procedure sheds approximately —% of electrical equipment. All equipment that remains powered is supplied via the circuit breakers on the overhead panel.

A

75%

11
Q

Maintaining the IDG PB-Switch more than —seconds may damage the disconnection mechanism.

A

3 seconds

12
Q

During the Preliminary Cockpit Preparation Battery Check/Setup, if the aircraft has not been electrically supplied for 6 hours or more the battery voltages must be checked by selecting BAT 1 and 2 PB’s to off and checking the voltages are above:

A

25.5 V (ensures a charge above 50%).

If the battery voltage is at or below 25.5 a charging cycle of about 20 minutes is required.
