INSTALLATION FOR RESEARCH ON THE INFLUENCE OF NOISE CRITERIA PRIMARY ELECTRICAL

摘要

The invention relates to means for carrying out research in the field of electrical safety, in particular, to study the effect of noise on the primary electrical safety criteria. solving task - to determine the dependence of the threshold current of different types of tangible and often from exposure to different types and levels of noise. The installation comprises a noise source in a PC and the simulated voltage source, electrodes, a block recording apparatus comprising an ammeter and a voltmeter. The unit is equipped anechoic chamber for receiving the test, on the ceiling and the walls of which there are speakers connected to the sound source, and which is equipped with indicator lights and webcam Logitech Webcam to control subjects. One of the electrodes is provided with a lock button for self test applied to the signal electrodes, wherein the source of simulated stresses is designed as a PC and is provided with a set of creating and applying a voltage of any shape, frequency and slew rate. 3 yl.
