Easy Insulation Integrity Testing and Quality Control with the HV Diagnostics HVA30 VLF and DC Hipot Tester

  • Uncategorized

High potential testing is a diagnostic method used to determine the condition of insulators. It gives a pass or fail result. The test is conducted by applying a voltage to the test sample above its rating. Ideally, insulators should be able to maintain resistivity to current even 2-3 times above the rated voltage. Most insulators have an allowance above its rating to be able to handle temporary voltage variations. 

AC high potential test is often used for insulators of electrical components that have been in operation for a while. DC hipot test on the other hand is only applicable for electrical components that are about to be commissioned. If you are planning to invest in a tester for regular preventive maintenance and quality control of insulators, consider the HV Diagnostics HVA30 30 kiloVolt VLF and DC hipot. These tester integrates 2 functions in one device. You have the option to conduct a VLF or DC high potential test to loads of up to 5 μF.

Other features of the tester include:

  •        Automated and manual cable test sequences
  •        Real-time display of the output waveform
  •        Automated measurement of capacitance and optimal selection of frequency
  •        Internal memory for storing test results
  •        Symmetrical sinusoidal output voltage
