A

CSD1 & CSD2

125
Q

Following a HOT/LOP condition in the CSD, the FAULT light will illuminate and IDG1/2 caution message will present. How can the IDG be disconnected?

A

Manually by the crew, or automatically by system protection.

Once disconnected, the IDG cannot be reconnected in Flight!!!!!!

126
Q

What does the AUTO XFER FAIL condition mean to?

A

The systems that are still operating are being protected from the failed bus.

The transfer was inhibited, not failed. If one of the buses has a short circuit, a transfer of excess kVA will fry the others, too.

There will be other messages, run the AUTO XFER FAIL QRH first.

127
Q

True or false: DC ties are completely automatic. They will close after system failures to prevent critical DC buses from losing power.

A

True

What happens if you turn OFF the battery master switch in flight?

What happens when you turn it ON?

A

Nothing - it removes connection between that BATT BUS and MAIN and APU Direct Buses.

BATT MASTER ON - APU & MAIN BATT direct BUS connect to the BATT BUS.

136
Q

In flight what powers the DC BATT BUS?

A

ESS TRU 2

137
Q

What occurs when you select the DC service switch to on, and from where will the DC service bus receive its power?

A

DC service bus is powered by the APU BATTERY DIRCT BUS. Service & boarding lights, NAV and LAV lights & galley lights

138
Q

What are the approximate voltage, phase and frequency of the AC power?

A

115 V, three phase, 400 Hz

139
Q

The AC ESS XFER switch light has illuminated, what does this mean?

A

AC bus 2 is it now powering the AC essential bus. The logic is flipped

140
Q

What is the GCU priority for AC bus 1?

A

On side, inside (APU), cross side, outside (external)

141
Q

What is a constant speed drive (CSD) and how is it depicted on the AC electrical synoptic?

A

Uses internal oil system to change engine variable speed into a constant RPM required for generator operation.

It’s depicted as an IDG!

142
Q

What would cause the IDG to automatically disconnect?

A

Severe over temperature or over torque

143
Q

Following disconnect, can the IDG be reconnected in Flight?

A

No maintenance must do it on the ground

144
Q

What would you see on the electrical panel as a result of a TRU 1 failure?

A

Nothing on the panel, but you would see the main TIE close and the utility bus shed on the electrical synoptic page and EICAS status messages

145
Q

When will the DC EMER bus appear on the DC electrical page?

A

Bus fault exists, or when it’s power sources are not powered.

146
Q

What would you lose following a DC EMER bus failure?

A

Fire protection, squibs and SOV

147
Q

Where would the ESS TRU 2  transfer Contactor be visible, and what would cause it to close?

A

Located in the upper right on DC synoptic and it will show when there are multiple failures.

148
Q

What will cause the ADG to automatically deploy?
