Power Input Characteristic Measurement System for Airborne Electrical Equipment Based on Labview

The power input characteristics of airborne electrical equipment directly affect the stability and reliability of the aircraft power grid. This characteristic must meet the requirements of the international standard ISO-1540. In view of the airworthiness certification of airborne electrical equipment, a detection system for the power input characteristics of airborne AC electrical equipment based on virtual instrument technology is designed. The detection model is determined. The system adopts NI high-speed data sampling card and labview, and automatically compares the detection results with standard indicators. In order to ensure the accuracy of the power input characteristic measurement, the system has the function of detecting the quality of the power supply. Experimental results show that the system can provide rapid testing methods for airworthiness certification of airborne electrical equipment.
