Description / Abstract:
This SAE Aerospace Information Report (AIR) considers the
following major areas:
1. major components and their ratings;
2. selection criteria for optimum design balance for electrical
systems;
3. effects of operating conditions and environment on both
maintenance and life of components;
4. trouble signals - their diagnosis and cure.
Purpose
Electrical systems engineering is the modern concept of
integrating load requirements with generator/alternator and battery
capacity and regarding this electrical equipment as a complete
system rather than a collection of independent units. The old adage
"a chain is not stronger than its weakest link" is particularly
valid for electrical circuits. So great care must be taken in
selection of equipment and in considering the operating position
and environment in which the equipment is expected to function.
