ELECTRICAL MENU System presentation 1/41 ELECTRICAL MENU System presentation 2/41 The A320 electrical system looks very much like electrical systems which you are familiar with. It is simply more automatic and easier to use. ELECTRICAL MENU System presentation 3/41 GEN 1 GEN 2 GEN 1 TThheerree aarree ttwoo eennggiinnee ddrriivveenn ggeenneerraattoorrss.. GEN 2 ELECTRICAL MENU System presentation 4/41 GEN 1 The generators maintain a constant speed by a drive mechanism known as an Integrated Drive Generator (IDG). GEN 2 IDG 1 IDG 2 ELECTRICAL MENU System presentation 5/41 Each generator supplies Alternating Current (AC) to its own bus: • Generator 1 to AC bus 1, • Generator 2 to AC bus 2. GEN 1 GEN 2 IDG 1 IDG 2 AC 1 AC 2 ELECTRICAL MENU System presentation 6/41 AC 1 AC 2 TR 1 TR 2 GEN 1 GEN 2 IDG 1 IDG 2 ELECTRICAL MENU System presentation 7/41 AC 1 AC 2 Each AC bus supplies its own Transformer Rectifier (TR): • AC bus 1 to TR 1, • AC bus 2 to TR 2. The TR convert alternating current into direct current (DC) to supply their associated DC buses, DC 1 and DC 2. GEN 1 GEN 2 TR 1 TR 2 IDG 1 IDG 2 DC 1 DC 2 ELECTRICAL MENU System presentation 8/41 AC 1 AC 2 GEN 1 GEN 2 TR 1 TR 2 IDG 1 IDG 2 DC 1 DC 2 DC BAT ELECTRICAL MENU System presentation 9/41 AC 1 AC 2 GEN 1 GEN 2 TR 1 TR 2 DC bus 1 then, feeds the DC BAT bus (DC BAT). The DC battery bus can charge the batteries or receive power from the batteries, as required. This will be explained further in Normal operation. IDG 1 IDG 2 DC 1 DC 2 DC BAT BAT 1 BAT 2 ELECTRICAL MENU System presentation 10/41 AC 1 AC ESS AC 2 GEN 1 GEN 2 TR 1 TR 2 DC ESS IDG 1 IDG 2 DC 1 DC 2 DC BAT BAT 1 BAT 2 The electrical system also includes two essential buses. The first one is the AC ESS bus fed by AC bus 1 and the second one is the DC ESS bus fed by DC bus 1. ELECTRICAL MENU System presentation 11/41 AC 1 AC ESS AC 2 DC ESS GEN 1 GEN 2 TR 1 TR 2 This is the basic electrical system. We will now introduce some other components which supply the basic system. IDG 1 IDG 2 DC 1 DC 2 DC BAT BAT 1 BAT 2 ELECTRICAL MENU System presentation 12/41 AC 1 AC ESS AC 2 DC ESS GEN 1 GEN 2 TR 1 TR 2 The electrical network can also be supplied by the APU generator. APU GEN APU GEN IDG 1 IDG 2 DC 1 DC 2 DC BAT BAT 1 BAT 2 ELECTRICAL MENU System presentation 13/41 AC 1 AC ESS AC 2 DC ESS GEN 1 GEN 2 TR 1 TR 2 These three generators are all identical and any one of them can supply the entire aircraft electrical needs. APU GEN IDG 1 IDG 2 DC 1 DC 2 DC BAT BAT 1 BAT 2 ELECTRICAL MENU System presentation 14/41 DC ESS AC 1 AC ESS AC 2 GEN 1 GEN 2 TR 1 TR 2 APU GEN IDG 1 IDG 2 DC 1 DC 2 DC BAT BAT 1 BAT 2 On the ground, the aircraft can be supplied by an external power source. ELECTRICAL MENU System presentation 15/41 As a backup, there is a hydraulically driven EMERgency electrical GENerator (EMER GEN). AC 1 AC ESS AC 2 TR 1 TR 2 DC 1 DC ESS DC 2 GEN 1 GEN 2 DC BAT BAT 1 BAT 2 APU GEN EMER GEN IDG 1 IDG 2 ELECTRICAL MENU System presentation 16/41 The hydraulic power to drive the EMER GEN is provided by a Ram Air Turbine (RAT) located in the belly fairing which extends in case of severe electrical or hydraulic failures. AC 1 AC ESS AC 2 TR 1 TR 2 DC 1 DC ESS DC 2 GEN 1 GEN 2 DC BAT BAT 1 BAT 2 APU GEN EMER GEN IDG 1 IDG 2 ELECTRICAL MENU System presentation 17/41 DC ESS AC 1 AC ESS AC 2 GEN 1 GEN 2 TR 1 TR 2 APU GEN ESS TR EMER GEN IDG 1 IDG 2 DC 1 DC 2 DC BAT BAT 1 BAT 2 The electrical system is also fitted with an ESSential Transformer Rectifier (ESS TR). We will see the EMER GEN and the ESS TR in detail in the Abnormal operation module. ELECTRICAL MENU System presentation 18/41 AC 1 AC ESS AC 2 DC ESS GEN 1 GEN 2 TR 1 TR 2 APU GEN ESS TR EMER GEN Now, let's see how this information is presented to the pilots in the cockpit. We will introduce the ECAM ELEC page. IDG 1 IDG 2 DC 1 DC 2 DC BAT BAT 1 BAT 2 ELECTRICAL MENU System presentation 19/41 DC ESS AC 1 AC ESS AC 2 GEN 1 GEN 2 TR 1 TR 2 APU GEN ESS TR EMER GEN You can see that all the components we have talked about are displayed on the ECAM page. Notice that each component has a title to aid identification. Let’s briefly review the basic system using the ECAM ELEC page.

ELECTRICAL MENU System presentation 24/41 For simplification the component indications have been removed, let’s now present them. ELECTRICAL MENU System presentation 25/41 As shown, each component can be monitored via its indications.

Let’s now locate the various controls available to the pilots and associate them with the components displayed on the ECAM. ELECTRICAL MENU System presentation 31/41 The ELEC panel is located on the overhead panel . ELECTRICAL MENU System presentation 32/41 For emergency cases, there is an EMER ELEC PWR panel on the left side of the overhead panel. Now let’s look at the relationship between the ELEC panel and the ECAM ELEC page. ELECTRICAL MENU System presentation 33/41 The battery voltage can be monitored either on the overhead panel or the ECAM page. ELECTRICAL MENU System presentation 34/41 Eaacchh bbaatttteerryy iiss ccoonnttrroolllleedd bbyy aa ppbb ssw.. ELECTRICAL MENU System presentation 35/41 Both main generators and the APU generator are controlled by their associated pb sw. ELECTRICAL MENU System presentation 36/41 The external power is also controlled by a pb sw. We will learn how to use it in the Normal operation modules. ELECTRICAL MENU System presentation 37/41 The AC ESS FEED pb sw enables the pilots to change the feed for the AC ESS bus from AC bus 1 to AC bus 2. ELECTRICAL MENU System presentation 38/41 The BUS TIE pb sw enables the pilots to isolate one side of the system from the other. You will see and do this in the abnormal operation modules. ELECTRICAL MENU System presentation 39/41 In case of failure, these pb sw enable you to disconnect an IDG from its drive shaft. ELECTRICAL MENU System presentation 40/41 The controls and indications on the EMER ELEC PWR panel will be covered in the abnormal operation modules. There is one exception. The EMER GEN TEST sw is used by maintenance only to test the emergency generator. ELECTRICAL MENU System presentation 41/41 In this module, you have seen the electrical configuration on ground, with both engines running and with APU generator and external power available. We will introduce you to the different possible configurations in the next modules.
