High-potential testing is routinely used to assess the ground insulation of AC stator windings in-process, after completion of a rewind and post-delivery. This webinar covers:

  • Differences between AC and DC high-potential tests
  • Sizing AC test sets when testing large windings
  • What relevant standards address (and what they don’t)
  • Communicating test requirements to all stakeholders
  • When to test and at what levels
  • How to evaluate results

Beneficial for service center managers, supervisors and technicians responsible for high-potential testing.
