AC GENERATION MONITORING AND INDICATING - DESCRIPTION AND OPERATION

** ON A/C NOT FOR ALL

1. General
Monitoring and indicating of the Alternating Current (AC) generation and distribution is done with the Electronic Centralized Aircraft Monitoring (ECAM) system which displays the electrical parameters related to:

the two Integrated Drive Generators (IDG)s,
the Auxiliary Power Unit (APU) generator,
the Constant Speed Motor/Generator (CSM/G), (emergency generator),
the static inverter,
the electrical ground power unit.

2. System Description

AC Generation Monitoring and Indicating - ECAM

The following AC electrical parameters are shown on the ELEC page of the lower ECAM Display Unit:

the oil outlet temperatures, the low oil pressure indication and the disconnection status of each IDG,
the voltage, frequency and nominal load in percentage of each main generator and APU generator,
the status of the AC normal and essential busbars,
the status of the galleys and the commercial loads; the ECAM also gives a synoptic of the AC generation system which tells the flight crew what is the electrical configuration,
the voltage and frequency of the ground power unit, the emergency generator and the static inverter.

3. Operation/Control and Indicating

A. Operation

The ELEC page on the lower ECAM Display Unit is shown:

either automatically after a class 1 failure on the AC network (if requested by the Flight Warning System (FWS)),
or manually if the ELEC page is selected on the ECAM control panel (Ref. 31-56-00).
