The TREX R is a three-phase voltage vector measuring option for the TR-Spy Mark II. It is a rugged, portable, option that allows the operator to test the phase relationships of transformer windings while applying three phase voltage. 

This option can precisely measure the angular relationship of transformer phases. This option is especially useful for transformers with phase ralationships other than 30 degrees and Zig-Zag types.
