odm IR SF6 density sensor for transformers

Network Protectors obtain control power from the network transformer secondary. Westinghouse NWP's, for example, use a control power transformer while GE taps right off the line and steps down voltage with resistors. In either case, the network transformer supplies voltage. If the transformer goes down, there is no other source for control power.
