Additional Product Information

Features & Benefits
  • With big LCD to show the measurement data;
  • With mini-printer to print out the test data;
  • Automatically recognize the test object whether it is capacitive, inductive or resistive, easy operation;
  • Can connect an external standard capacitor, or connect an external oil cup to measure the dielectric loss of insulation oil, or connect measuring electrodes to measure the dielectric loss of solid insulation material.
  • Automatically recognize 50Hz/60Hz power source;
  • With Series or Parallel methods of measurement;
  • Automatically recognize external HV power source with frequency between 40-70Hz, can be used together with AC test transformer or AC resonant test system;
  • 100 test results storage facility, computer interface.

It can be used to measure the dielectric loss on site (power plants or substations) or in the lab (load capacitor, capacitive voltage divider, current transformer, grading capacitors, surge arresters, shunt reactors, bushings, etc ).
