ELECTRIC CIRCUIT AND ARC DETECTION SENSOR AND GLAZING WITH USAGE OF ABOVE CIRCUIT AND SENSOR Russian patent published in 2015 - IPC H05B3/86 

FIELD: electricity.

SUBSTANCE: electric circuit sensitive to overheating and/or electric arc generating at an electroconductive element, for example, a heating element of any aircraft windshield, comprises the first switch in the first passway of electric current and the second switch in the second passway of electric current. The first passway of electric current passes from the power supply source through the first switch, through arc detection sensor to the heating element and to the power supply source. The second passway of electric current passes from temperature sensor controlling temperature of the heating element through the second switch to temperature controller. When temperature of the heating element is equal or higher than the preset value temperature controller opens the first switch. When arc is generated the second switch is transferred to open condition. The temperature controller reads the data that the second switch is open and opens the first switch.

EFFECT: excluded overheating or arc generating.
