METHOD OF ELECTRICAL PROTECTION OF THE ELECTRICAL POWER SUPPLY OF ELECTRICALLY CONTROLLED SYSTEM WITH VARIABLE OPTICAL PROPERTIES OR LIGHTING SYSTEM, APPLICATION OF ELECTRICALLY PROTECTED SYSTEM

摘要

The present invention relates to a method of electrically protecting a source (1000) of electrical powering an electrically controlled system (100) with variable optical properties located near water, wherein the electrically controlled system comprises a substrate (4, 5) carrying an electrically active element (3) located between and the second electrodes (1, 2) fed by a periodic voltage U (t) with a given maximum effective value U0 at a given low frequency of power, and the method contains the steps to limit reaching potential at the input (1a) or output (2a) contact of an electrically controlled system with a maximum value less than or equal to 50 V, and the attained potential is defined as the potential acting on the human body in case of contact with the input or output contact. The invention also relates to applications of the electrically controlled system thus protected.
