Triad Magnetics
Looking for Current Sense Transformers Current sense transformers "transform " AC electrical currents from larger-current values into smaller currents that are better suited for instruments, protective relays, and control circuits. This is achieved by developing a current in the secondary winding that is proportional to that of the primary. The isolation aspect of the transformer keeps the high voltage of the primary system separate from the instrument, safety circuit, or control circuit on the other side, thereby protecting them...

Majestic Transformer Co.
Low Inrush Transformers We were approached by a client who was experiencing problems with inrush start up currents on conventional transformers. On long cable runs these high inrush currents (typically 10 - 15 times the full load current of the transformer can be experienced) were causing excessive cable voltage drops and causing other equipment on the supply to drop out. After some discussion with the client, it was decided that the options of offering some form of inrush suppression were not suitable...
