I'm looking to measure an analog voltage signal in the range 0 - 100 V. The system has a 15 kV power supply and is typically running about 500 Amps.
I want to drop the voltage by a factor of 10 or 20. In the past I've used an optical isolator system like this to attenuate the voltage as well as do some signal conditioning.
I'm generally happy with the results, but product requires a module with a large footprint (their smallest module supports 8 channels and I only have the one).
My question is whether a simple voltage attenuator will work, and where to look to find one designed to handle 100 V signals. Would something as simple as these 20:1 attenuators that mechanics use work? I need 0 - 10 kHz bandwidth, but the more the merrier.
