The electrical power generation is provided by the following sources : R -
Main and emerge emergency ncy batteri batteries es Two engine-driv engine-driven en DC starter/genera starter/generators tors Two AC wild wild freque frequency ncy generators generators Two external external power power units (AC (AC and and DC) DC)
In addition, two static inverters (supplied by the DC system) provide constant frequency AC power. The ACW electrical system can also supply DC electrical system through a transformer rectifier unit (TRU). The electrical distribution is ensured by busses which feed equipments. Two seperate networks (left and right) run individually and can be connected in case of generation failure thanks to bus tie contactors (BTC).

DC SVCE BUS
The DC SVCE BUS supplies power in flight, and on ground during airplane servicing operations. The DC SVCE BUS can be supplied by : - DC BUS 1. 1. The master master sw is the the DC SVCE/UTLY SVCE/UTLY BUS pb. When When selected on, the cabin attendant controls the DC SVCE BUS supply from a sw located on the cabin attendant control panel. - EXT PWR. Only the the cabin attendant pb has control. The The supply of the BUS BUS may be be performed with batteries switched OFF. OFF. GND HDLG BUS
The GND HDLG BUS supplies the DC loads required for airplane servicing on the ground even with BAT sw selected OFF. Since these loads are not required during flight, the GND HDLG BUS is deenergized in flight. The GND HDLG BUS can be supplied : - When EXT PWR is available, available, from DC SVCE BUS. - When EXT EXT PWR is not available, from HOT MAIN BAT BAT BUS provided : D Cargo door operating panel door is open (micro switch), or D Refueling panel is open (micro switch), or D Entry door is open (micro switch). TRANSFER (see schematics p. 15 to p. 26) With all switches in normal position, the DC power transfer is achieved by automatic automatic opening and/or closure of electrical contractors according to the part icular electrical conditions. - On gr ou ound D When EXT PWR is connected (p. 15/16) Note : The electrical power power transfer is achieved in the same way as in flight as long as EXT POWER is not connected. - I n fl ig ight D Both engine driven generator operating (p. 19/20) * The engine driven generator 1 supplies the DC BUS 1, * The engine driven generator 2 supplies the DC BUS 2, * The BTC is open.

30.1 DESCRIPTION GENERATION
The source of constant frequency (400 Hz) AC power consists of two static inverters (INV). The inverters are rack mounted and cooled by forced air with provisions for natural convection cooling. The static inverter design characteristics are as follows : - Po w er 500 VA - O ut pu t v ol t age 115 V " 4V and 26 V " 1V - F r e qu enc y 400 Hz " 5 Hz - Type s i ng l e ph as e The two inverters are powered respectively from DC BUS 1 and DC BUS 2. The input voltage range is between 18 VDC and 31 VDC for satisfactory operation. In event of one DC BUS loss, loss, corres ponding inverter is not supplied, but corr esponding AC BUS is supplied by AC BTR (BTC pb). In event of both DC BUS power loss, INV1 is automat ically suppli ed by HOT MAIN BAT BAT BUS, or by HOT EME R BAT BUS BUS in OVRD configu ration ratio n or by TRU when selected ON. The maximum power available on each 26 VAC BUS is 250VA.
