Characteristics of aircraft electrical system1 ScopeThis standard specifies the characteristics of airborne electrical equipment supply power input, in order to adapt to a variety of power on the new civil aircraft and set Meter electrical equipment [such as by technical standards (TSO) certification of electrical equipment] provides an interface definition. It has a single purpose or special Equipment for military purposes do not comply with this standard, in order to avoid due to the pursuit of multi-purpose and lead to reduced device performance. This standard also provides a background of the development of these requirements for modern aircraft electrical system design and (or) integrated reference. Power quality is Results supply, power distribution and electrical equipment interaction. Once the specified limits for electrical equipment, will determine the support of the whole system open Background made of key interfaces power supply and distribution equipment. This standard takes into account the type and variety of power distribution parameters in both small and large transport category aircraft are likely to encounter. Power is divided into Rotary And static variant, could be onboard power supply, it may be used as one of the ground support equipment ground power. This standard relates to the supply voltage Species Category are. --- DC 14V, 28V and 42V (nominal value); --- Single-phase AC 26V400Hz (nominal value); --- Single-phase or three-phase AC 115V/200V and 230V/400V (nominal value), constant frequency or range of frequencies including 400Hz 400Hz Frequency.2 Normative referencesThe following documents for the application of this document is essential.
