4-20mA to 110Vac
4-20mA to 110Vac
(OP)
Hello,
I need to send the secondary 110Vac/sqrt(3)of a HV metering PT, to a remote location at around 5 km. I have found analogue to digital converters and signal transmission through fiber optic. However, for the remote end, I require also a 110Vac/sqrt(3) output, and I am only able to find digital to 4-20mA or 0-10V transducers.
Anyone can tell me a solution for this?

In principle what you're asking can be done, but is it a good solution? What are you connecting to?

Meters often have the capability to compensate for losses between the metering location and the contractual point of sale. Perhaps you can put the tariff metering at the plant and then program the compensation values to calculate the plant?
