These 110 Volts AC Wattmeters are ex old substation panels, and can easily be modified for a linear reading Wattmeter on mains voltage via a CT. A 230/110 Volts transformator has to be used for the potential coils in the meter. By adding a certain amount of primary turns on a 400/5 or 200/5 Amp CT a nice vintage Wattmeter with linear schale is made.
