Ok thanks for clarification

my device is used to test the insulation of the electrical equipments by applying high voltage DC to the device and merasuring the leakage current to the earth I observed that my device always injects negative votage instead of positive voltage with a zero volt on the other side of tested item...

my device supplies negative (-V) to the tested item and a zero volt to the Earth and this zero volt terminal is the earthing terminal of the test device it does not provide +v and -v I hope you understood what i mean

Hi every body I've some question that need to be answered WHy DC high voltage test devices always generate negative voltage rather than positive voltage I hope that i can get an answer Thanks
