본 장치는 Raytech사의 권수비시험기에 연결되어 각변위를 측정하는 장치이다. 본 장치는 삼상전원을 동시에 변압기에 인가하여 변압기의권수비와 각변위를 정밀하게 측정할 수 있는 장치이다.
특히 30˚ 이외의 각변위 측정에 전세계 유일한 제품이다.

The T-Rex is a three-phase Voltage Vector measuring option for the TR-Spy Mark II. It is a rugged, portable, option that allowsthe 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 fortransformers with phase ralationships other than 30 degrees and Zig-Zag types.
