Hi,

Is there a circuit that can maintain power factor for two different transformers at the same time? I'd like it to just use a single power factor relay, if possible.

 

The control relay adjusts the amount of capacitance that is cut in and out of the circuit.

So, no. Two transformers = 2 relays.

 

So each transformer will need it’s own power factor relay and its own set of capacitors? Correct?

 

Unless your transformers are connected in parallel ... I'm going to assume you cannot combine the equipment ... They have to have their own control components.
