Portable Transformer Test Equipment

Portable Transformer Ratio Test Set TTR2000A

Main Features
1. The tester makes automatic measurement with no need to set any parameters and automatically

completes the three-phase ratio and connection group measurements with easy operation.

All you need to do is to press a button.
2. The tester measures three-phase and single-phase transformer ratios automatically,

and calculates the ratio error.
3. The tester has inner three-phase signal source, which can make measurement of Y / y, Y / d, D / y, D / d,

ZN / y, ZN / d, rectifier transformer, traction transformer and all kinds of ratios of transformer connection groups.
4. The tester can measure transformer connection group label and polarity to clearly display the first and

second winding connection vector.
5. The tester can track the transformer on-load tap-changer position automatically, and indicate the current

tap point automatically.
6. The tester can display a transformer’s first and secondary voltage Oscillograms and phase relationship.

It can measure transformer’s first and second harmonic voltages, to facilitate the analysis of transformer failure.
7. The tester has perfect and reliable automatic protection, to ensure the intactness of the tester under abnormal conditions.
8. The tester is has small size and light weight. It makes accurate measurement at fast speed (about 3 seconds to complete the test).
