The Raytech T-REX! It’s actually a pretty versatile piece of equipment used in the electrical testing world. Depending on the specific context, it can refer to two different things:
1. Three Phase Voltage Extension to Turns Ratio Meter:
This T-REX is an optional accessory for Raytech phase transformer ratio meter test sets like the TR-Mark III & TR-Mark III 250v. It allows you to measure the phase relationships and actual voltage ratios of transformer windings while applying three-phase voltage. This means you can get a real-world picture of how the transformer will operate when connected to a three-phase system, rather than just testing it statically.
Here are some key features of this T-REX:
- Measures the ratio and angular relationship of transformer phases with voltage applied to all three phases simultaneously.
- Especially useful for transformers with:
- Uncentered neutral points
- Phase relationships other than multiples of 30°
- Zig-Zag windings
- Suspected broken, damaged, or missing core laminations
- Compact and rugged construction for field use.
2. Three Phase Voltage Vector Option for TR-Mark II:
This T-REX is a specific option for the TR-Mark II phase transformer ratio meter test set. It provides a portable solution for testing the phase relations of transformer windings while applying three-phase voltage.
Here are some key features of this T-REX:
- Precisely measures the angular relationship of transformer phases.
- Ideal for transformers with phase relationships other than multiples of 30°.
- Rugged and portable design for field applications.
