High Voltage Testing Laboratory Overview

Quality voltage testing services and a world-class HV test facility for the reliable support of informed industry decision-making.

Proven Capabilities

Kinectrics High Voltage (HV) laboratory offers HV/EHV testing for HV products development and standards conformity with focus on:


  • Line Hardware
  • Power Cables
  • Insulators
  • Transformers
  • Switchgear

Voltage endurance tests for transmission and distribution equipment rated up to 500 kV under Lightning Impulse, Switching Impulse, DC and Power Frequency Voltages are performed routinely. HV testing expertise extends to comprehensive indoor, outdoor, mobile and specialized environmental test facilities.

For over 30 years, electrical industry transmission and distribution research programs have been conducted and verified at Kinectrics’ HV laboratories. Manufacturers, product development, and testing standards parties have used our HV laboratory capabilities and facilities for voltage apparatus and insulation systems performance testing. Customer involvement is always welcome.

Setting Industry Standards

Kinectrics’ teams of engineers, scientists, and technologists are actively involved in standards committees (including national and international working groups at CSA, CIGRE, IEC, IEEE) supporting the evaluation of new materials and their environmental impacts, and the development of advanced high voltage test methods. Our ongoing involvement in research means Kinectrics remains up-to-date with new products and technologies.

Kinectrics’ HV laboratory routinely performs tests to ANSI, UL, IEEE, AEIC, NEMA, CEA, IEC and other national and international standards including:

  • Visual Corona Test
  • Radio Interference Voltage (RIV) Test
  • Contamination (solid layer, clean fog method)
  • Partial Discharge Testing
  • Wet and Dry Power Frequency Withstand and Flashover Test
  • Dry Lightning Impulse Critical Flashover and Withstand Test
  • Steep Front Impulse Voltage Test

Kinectrics’ HV laboratory also performs non-standard testing based on customer specified or mutually agreed on test programs

  • Customized Test Programs for Research and New Product Development

Typical tests conducted in Kinectrics’ HV laboratories:

  • Lightning and switching impulse tests on power apparatus
  • Visual corona and RIV tests on transmission and substation hardware
  • Partial Discharge tests on internal insulation
  • Load cycling and qualification tests on high voltage power cables
  • Impulse tests on transformers
  • Contamination testing of external insulation
  • Design and Type Tests on polymeric, porcelain and glass insulators

Environmental Test Chamber

In addition to Kinectrics’ HV testing capabilities, the HV Lab operates an Environmental Testing Chamber capable of simulating cold fog conditions continuously, while monitoring the performance of insulation up to test voltages of 350 kV.
