Feb 21, 2018 This is an electrostatic polarity detector with increased sensitivity. This device makes it possible to investigate the polarity of the high voltage. RED LED = Positive, BLUE LED = Negative, Both LED = Alternating Voltage On the HVDC line, only one LED will be on. How to make an Electrostatic Polarity Detector :
