Three Phase 250V Transformer Turns Ratio Meter
Features
- Fully automated measurement of turns ratio, voltage ratio, phase displacement, and excitation current.
- Better transformer excitation due to higher test voltage of 250V.
- Highest accuracy on the market - up to 0,03%.
- Ratios of up to 50’000 can be measured
- Measurement of phase displacement of transformers with irregular vector groups like: phase shifting, rectifier, arc-furnace and traction transformers.
- Automatic Winding Connection Identification (AWCI) and automatic vector group detection supports quick and easy operation.
- Quick setup with intuitive guide-through user interface. Test setups and results can be stored and recalled, printed out with the built-in printer or used for later analysis.
- Lightweight, rugged and compact design allows use in harsh environment (field proof). Closed case is IP65 waterproof, open case is splash proof.
- Safety connection control feature proofs test setup before applying regular test voltage to guarantee safety of the personnel and instrument.
- Free external application software allows data exchange and advanced analysis of results on a computer (USB connection) including automatic report generation.
- Remote tap changer switch enables convenient testing of multi-tap transformers.
