Tool/software:
In our 800 V HVDC network, we have implemented a resistor divider network on the line path, but not on the return path since no negative supply is available from the source. However, in the reference design, resistor divider circuits are used on both the positive and return paths for insulation monitoring. We would like to confirm whether our approach is correct, or if the HVDC return path also requires a resistor divider network.
