Description
The Meco TTR 8100 Transformer turns ratio meter is a portable instrument for accurate measurement of 1-phase and 3-phase Transformer VT/CT Turns Ratio, Excitation Voltage, Current, Phase Angle and Deviation.
TTR-8100 ensures the correct turn ratio and quality of the transformer. It checks live test points, Open circuits, and reverse polarity before each measurement.
Features:
- Measurement of 1 Φ and 3 Φ Transformer / VT / CT Turns Ratio
- VT / PT Ratio 0.8 ~ 2000, Ct Raio 0.8 ~ 2000
- Graphical and Literal Illustration of Measurements and Connections with Large Back – back-lighted dot Matrix 240 x 128 LCD
- Displays Turns Ratio, Deviation, Secondary Output, Excitation Voltage, and Current, Phase Angle and Nameplate. Transformer VT / CT Values on one page for easy quality interpretation
- Check for Live Test Points, Short Circuits, Open Circuits, and Reverse Polarity before each measurement
- Store 4096 Files of Transformer Nameplate Values (VT / PT / CT 1 Φ / 3Φ, Test Frequency, Primary and Secondary Voltages or Ratio, RCF) and Measuring Data.
- Ten Test Frequencies (50 ~ 400 Hz)
- 9 Types of 3 Φ Winding Connection pre-installed
