Transformer Turns Ratio Meter
- Measurements of 1Φand 3ΦTransformer/VT/CT Turns Ratio.
- VT/PT ratio 0.8~10000, CT ratio 0.8~2000.
- Graphical and Literal Illustration of Measurements and Connections with Large Back-lighted Dot Matrix 240 x 128 LCD. Display Test Data with Nameplate Transformer Values for Easy Interpretation.
- Ten Test Frequencies (50~400Hz).
- Display Turns Ratio, Deviation, Secondary Output, Excitation Voltage and Current, Phase Angle and Nameplate Transformer/VT/CT Values in one page for easy transformer quality interpretation.
- Check for Live Test Points, Short Circuit, Open Circuit, and Reverse Polarity before Each Measurement. Message is displayed to Warn Users (But, checking is not performed once measurement starts).
- Store 4096 Files of Transformer Nameplate Values (VT/PT/CT, 1Φ/3Φ, Test Frequency, Primary and Secondary Voltages or Ratio, RCF) and Measuring Data.
- 9 types of 3Φ Windings Connections pre-installed for easy user selection.
