• Diagnostic tools - Polarization index (PI), Dielectric discharge (DD) and Dielectric Absorption Ratio (DAR) with automated resistance ranging. All parameters can be measured and displayed in one single measurement. Advanced 5 kV Insulation Tester with Diagnostics Tools TYPICAL APPLICATIONS: • power transformers • Step voltage test - Insulation resistance will be measured at five different, • high voltage cables • R(t) graph - Real time resistance against time graph plotting facility to • rotating machines equality sequenced test voltages for profound insulation system diagnostics. graphically illustrate the response of a material to an applied test voltage. • surge arrestors 50 µF can be quickly charged and tested. • measuring transducers leads supplied in a standard set make the instrument suitable for accurate insulation testing in environments with high EM interferences like HV switchyards or similar. • High charging capacity - With 5 mA charging current insulation systems up to • High EM (noise) immunity - Built in noise rejection filters and shielded test • High protection level - CAT IV / 600 V overvoltage category for industrial • Lightweight and user-friendly design - TeraOhm 5 kV Plus is packed in a handy, rugged carrying case weighing only 3 kg. The new TeraOhm 5 kV Plus insulation tester has all necessary features for a profound insulation diagnostics. Automated calculation of PI, DD and DAR, combined with a possibility to perform a step voltage test make the instrument suitable for the most demanding customers and applications. Large LCD display allows real time R(t) graphs to be displayed. Windows compatible HVLink PRO PC Software and either RS232 or USB communications ports serve for connecting the instrument to the PC and management of the recorded test data. Electromagnetic compatibility: EN 61326 class B Safety: EN 61010-1 (instrument) EN
