test 2.5 element transducer

[stevencress]

We have an old relay test set, RTS-150 made by EIL (now Ametek). Having trouble wiring up 2.5 element watt transducers to this test set so that it can be tested with single phase amps and volts. Can anyone tell us how to wire the 12 lugs? Thanks

If it is similiar to a watthour meter, the middle current coil is wired backwards and has two current coils in it. So you have four current coils and two voltage coils and for math, treat it as a four element. All of that said IF it is like a watthour meter.
