TR1 RESET CONFIGURATION
When the fault disappears, the TR remains deactivated.
Reset action is necessary for TR reactivation.
The Transformer Rectifier protection reset is possible
either from the Centralized Fault Display System via
MCDU or from the pusbutton located in the avionics
bay.

TR2
The operation of TR2 is identical to that of TR1.
When AC and DC GRND FLT Buses are only supplied by
external power, the TR2 minimum current detection
system is inhibited.

SELF EXAMINATION
What are the protections for a Transformer
Rectifier unit?
A - Overheat and minimum current detection.
B - Overheat and overvoltage detection.
C - Overheat and overcurrent detection.
How can a Tranformer Rectifier unit be reset?
A - Either from the Battery Charge Limiter
or a pushbutton in the avionics bay.
B - Either from a pusbutton in the avionics
bay or automatically at power up.
C - Either from the Centralized Fault
Display System or a pushbutton in the
avionics bay.
When is the TR2 minimum current detection system
inhibited?
A - On ground when the aircraft electrical
network is supplied by the APU generator.
B - On ground when the AC and DC GRND FLT
Buses are only supplied by external
power.
C - On ground when the AC and DC GRND FLT
Buses are supplied by external power.
