METHOD AND SET OF EQUIPMENT FOR TESTING THREE-PHASE ELECTRICAL SUPPLY NETWORKS ON BOARD AIRCRAFT

摘要

FIELD: electricity.;SUBSTANCE: one connects the electric power supply lines and signalling lines to the input contacts (24) of the testing device (1) instead of the three-phase current consumer. One applies voltages to the electric power supply lines. One checks the voltages using the testing device (1) to determine whether the voltages applied to the electric power supply lines are equal to the preliminarily preset voltage values. Simultaneously with checking voltages one checks the phases using the testing device (1) to determine whether the phase shift of the voltages applied to the electric power supply lines is equal to preliminarily preset phase shift value. One ensures automatic connection of the input contacts (25) of the testing device (1) to the input contacts of the three-phase current consumer if the voltages and the voltage phase shift are equal to the preliminarily preset values.;EFFECT: ground tests simplification.;7 cl, 2 dwg
