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.

What size do you need? I also work for a utility and we have units in service sized from 200 KW to 5 MW.

Let’s compare apples to rotten tomatoes. If a request is for the utility to change/add to the service feeding the customer, then a PE is required in most municipals.

There use to be a device called something like Add-A-Phase, but I do not know if it is still being made.

As long as you do not need to test at 50% power factor. PF tests require three-phase input to the test set.

You are correct that an electromechanical meter will turn backwards unless it has a detent. Presently almost all of the single-phase solid-state meters will add negative flow as positive flow because negative flow normally is considered tampering. Industry is slowly reacting to the customer...
