Automatic Dielectric Constant Tan Delta & Resistance Bridge Automatic Dielectric Constant Tan Delta & Resistance Bridge Fully Automatic Dielectric Constant, Dielectric Dissipation Factor & Resistivity Measurement. ■ Inbuilt Printer Facility for Test Report Printing. ■ Easy Storage of Data. ■ PC Compatibility. ■ Fully Automatic Operation ■ Data Storage 250 test results in inbuilt memory The TDM-4000 is an automated instrument for measuring the electrical characteristics of transformer oil, insulating liquids & other insulating material samples. The TDM-4000 measures Capacitance, Dielectric Constant (I), Dielectric Loss, Tan Delta (Dissipation Factor), Resistance & Resistivity of the test sample. The Tan Delta value gives an indication of the condition of the oil sample. There are several reasons due to which the Tan Delta value may be affected - such as moisture, dissolving of some of the transformer varnish, insulating material deteoriating etc.

Oil sample dose - Start measuring - The result obtained TDM-4000 is especially designed to work with the IEC & ASTM type oil cell with a 2mm spacing and will apply a stress in the range of 100 - 1000 volts per mm as recognized by ASTM and other specifications. DESCRIPTION The model TDM-4000 is a versatile Test Set used for measuring the Dielectric Constant, Tan Delta (DF), Resistivity of transformer oils & other electrical insulating liquids or solid insulating materials in sheet form. The TDM-4000 is only the measuring instrument to test insulating liquids, it should be used with a three...
