Description

PE-AORDF-1 Fully Automatic Oil Resistivity & Tan-Delta tester is an integrated unit, consisting of Heater unit and Measuring Bridge. The Stainless Steel oil cell is to be mounted inside the HF Induction heater cubicle, and HV is engaged to it automatically. Measuring Bridge consists of AC/DC high voltage supply, Tera-Ohm meter, and precision electronic bridges to measure and derive readings for :

  • Resistance
  • Resistivity
  • Capacitance
  • Power Factor
  • Tan-delta
  • Watt-loss
  • Dielectric Constant
  • Temperature

Pre-programmed international test methods compliant to:

ASTM-D924-04, ASTM-D1169, IEC-60247, IEC-61620, IS-6262/6103, NBR 12133, VDE-0380-2, BS-5737

 

Features

  •  Complete automatic test procedure. Once test voltage is selected, it applies excitation to the 3-terminal Oil cell, measures R, C, DF, F, V, and then displays and prints the results on integrated printer
  • High Accuracy, Best resolution in its class
  • Pure Sine test operation for AC measurements and <0.1% ripple for DC measurements>
  • Heater interfaced with main unit for temperature set, control and display
  • Multiple temperature set values programmable
  • Programmable cell constant for Resistivity and Dielectric Constant
  • SF6 Gas Capacitor integrated inside for standard reference
  • 7″ color TFT display with touch screen with wireless keyboard for user convenience
  • Integrated Programmable AC & DC test voltages
  • Thermal printer for immediate printing
  • Pre-programmed 9 test sequences, and user-programmable 10 test sequences
  • USB 2.0 interface for PC
  • PC software for control and display of test results
  • On-site calibration possible for yearly schedule
  • Optional Bluetooth / RS485 / RF interface with user definable config, for Automated Laboratory setup
