Combined TTR & Winding Resistance Test Sets
Measure transformer turns ratio, winding polarity, phase displacement and winding resistance with one portable HVEX test set. The integrated touchscreen and Ethernet connection support use in the factory, laboratory and field.
Test functions
Turns-ratio testing for power, distribution and instrument transformers.
Winding polarity and phase-displacement checks.
DC resistance measurement on inductive loads, including transformer and motor windings.
Documented configuration
TTR output: 220 V; voltage ratio: 200.
Winding-resistance ranges: 100 µΩ–1 Ω and 1 Ω–5 kΩ.
Supply: 110 V or 220 V, 60 Hz.
Weight: 20.2 kg (44.5 lb).
Specify your transformer ratings, required test connections, resistance range and available supply when requesting a quotation. The combined instrument is distinct from the standalone TTR and 40 A winding-resistance testers.
