TES Transformer Turns Ratio Meter PROVA-1660

PROVA 1660
Transformer Turns Ratio Meter
Product Features
  • Transformator/VT/CT Turns Ratio 1 and 3 measurements
  • CT ratio of 0.82000, VT/PT ratio of 0.810000.
  • Using a large, back-lit dot matrix LCD, measurements and connections are graphically and literally illustrated. For simple interpretation, display test data with nameplate transformer values.
  • (50–400Hz) Ten test frequencies.
  • For simple understanding of transformer quality, display Turns Ratio, Deviation, Secondary Output, Excitation Voltage and Current, Phase Angle, and Nameplate Transformer/VT/CT Values on a single page.
  • Before each measurement, check for Live Test Points, Short Circuits, Open Circuits, and Reverse Polarity. A warning message is shown to users (But, checking is not performed once measurement starts).
  • Save 4096 files of measurement data and the transformer nameplate values (VT/PT/CT, 1/3, test frequency, primary and secondary voltages or ratio).
  • There are 9 different types of 3 Winding Connections pre-installed for user convenience.
  • Bluetooth wireless communication with a computer.
  • Choose a filter to eliminate field noise (Slow, Normal, Fast).
  • Auto-Power-Off with Programmable Time can be enabled or disabled.
  • Clock with calendar built-in.
  • Date and time stamped records.
  • 3400mAH powerful lithium battery with integrated charging circuit.
  • RCF (Reference Correction Factor, 0.99–1.01) is programmable by the user and corrects accuracy to within 1% error.
  • Friendly File System for Nameplate Values Management and Simple On-Site Data Retrieval.
  • includes PC application software.
