Aircraft Electrical System Testing with military standards

Aircraft Electric System Testing
MIL-STD-704 Guides Avionics Power Testing & Solutions:

Aircraft Electrical System Testing and other electrically powered equipment must be tested under extreme power conditions to ensure it will operate reliably once in the air. . In the military world, MIL-STD-704 (now up to rev. F), ‘Aircraft Electric Power Characteristics’, establishes the requirements and characteristics of aircraft electric power. The tests specified in the MIL-HDBKs is designed to ensure that airborne utilization equipment, which is defined as equipment that receives power from the aircraft’s electric power system, is compatible with the power system.

Envitest Lab is equipped with the sophisticated power source essential to simulate power conditions as per MIL HDBK 704.the test equipment used for compliance tests for airborne utilization equipment systems cover the latest versions of MIL-STD-704. MIL-HDBK-704-1 through MIL-HDBK-704-8 specify the following power groups.

SAC (single phase 115V/400Hz)
TAC (three phase 115V/400Hz)
SVF (single phase 115V various frequency)
TVF (three phase 115V various frequency)
SXF (single phase 115V/60Hz)
HDC (270V DC)
LDC (28V DC)
