Earth Fault Monitoring Equipment
Earth Fault Monitoring Equipment
(OP)
My project use Earth Fault Monitoring equipment in
Panel Distribution Board 24 VDC
( see this equipment in http://w ww.bender. org/ground _fault_for _ungrounde d_small_sy stems.aspx )
Anyway, I really want to know principle of it how it work
I just know that within this equipment, a measuring signal is generated
I just know that it is used for monitor insulation resistance
but the other things, I don't know how does it measure insulation resistance
and etc. like what wave form is generated, how does it know insulation resistance down..........
and many many question about it
I have a lot of question on it, because I don't know principle about this equipment
So, could you please explain me the principle of Earth Fault Monitoring

They have good descriptions on how insulation monitoring works, both for AC and DC systems.
Basically, the meter circulates a small current thru the power system and back to earth-ground. As that current increases, that shows the insulation decreasing.
There are filters and several other components, but that is the basics of it.
