Therefore, it can be used very well in test labs or be assembled into complete measurement systems. The T-Rex R three phase voltage extension is an optional system accessory for 3-Phase transformer ratio meter test sets designed by Raytech (i.e. TR-Mark III). The T-Rex R was designed to give Engineers and Test Technicians the ability to test the phase relationships and actual voltage ratios of transformer windings while applying three phase voltage.
The system (in connection with a 3 phase Raytech Turns Ratio meter) precisely measures the ratio and angular relationship of transformer phases with voltage applied to all three phases simultaneously. This is a “real condition” measurement, which allows greater understanding of how the transformer will operate connected to a 3 phase system.
The T-Rex R is especially useful for transformers with:
The T-Rex R comes complete to connect to the Raytech TR-Spy, TR-Mark II R, TR-Mark III R, or TR-Mark III R 250V three phase transformer ratio meter.
