The SAE ARP 5015 standard, developed by the Society of Automotive Engineers (SAE), includes ground power equipment requirements that can provide 704/400 V, 115-phase, 200 Hz output that can power aircraft-type loads that require power in MIL-STD-3E/DFS-400 standard quality. All 400 Hz ground power forms, including mobile and fixed systems, are covered by this standard.
The purpose of the SAE ARP 5015 standard is to provide specifications for engine generators and solid-state converters specifically designed for performance with modern aircraft, unless otherwise noted. Modern aircraft require uninterrupted higher quality power, which imposes new constraints on ground power units such as unity power factor and uninterrupted power transmission. The protective trip limits are designed to allow a two-stage protection using both the electrical power generation systems of the aircraft and the protection of the ground power units. Some of these specifications impose some new design restrictions on ground power manufacturers, but help support compatibility with all types of ground power equipment and older and new generation aircraft.
Ground power units are designed to provide the same quality of power as the electrical power generation systems of the aircraft. However, there are differences in nominal capacity.
When an aircraft is parked, it cannot use normal 400 Hz mains power as it needs 50 Hz power. As a result, airports require specialized ground support equipment. Ground power units play a vital role, allowing the aircraft to operate while on the ground.
The main advantage of ground power units is that they limit the use of onboard turbogenerators. Thanks to these units, there is a reduction in noise and air pollution. The ground power unit is connected to the normal 3-phase mains power supply and is connected to the aircraft with a special flexible cable of 200 V, Provides 3 phase 400 Hz power output. The converter only turns on when the aircraft needs power.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides testing services for 5015 Hertz ground power performance requirements among ground equipment within the scope of SAE ARP 400 standard, with its trained and expert staff and advanced technological equipment.
