Abstract:
1. Method for testing power lines and signal lines onboard of an aircraft, the power lines and signal lines connecting a 3-phase AC consumer with the power supply system of the aircraft, the 3 phase AC consumer having separate input terminals onto which, during operation of the 3-phase AC consumer onboard of the aircraft, predetermined voltages of predetermined phase difference are to be applied, the method comprising the steps of: connecting the power lines and signal lines with input terminals of a testing equipment, in place of the 3-phase AC consumer; applying voltages to the power lines; conducting a voltage test by the testing equipment in respect of whether the voltages applied to the power lines are equal to the predetermined voltages; conducting a phase test by the testing equipment simultaneously with the voltage test in respect of whether a phase difference of the voltages applied to the power lines is equal to the predetermined phase difference; and
