Any ideas...

Many thanks for both of you for alerting me on hall effect sensors. I will look into that. Here is more details of I want to do. I am going to use an isolated 1600VDC supply to operate a device about 200m away from the power supply (the cable length is about 200m long). I need to know if there is a ...

Hello, I need to design a line isolation monitor for a isolated DC power line. Just wondering whether you can give me a head start as where to you begin. I am thinking of biasing a small current (wrt to GND) to +V and monitor the return via ground back to +V. If there is no leakage from +V to GND th...
