How a webinar works

All EASA private webinars are live events in which the audio and video are streamed to your computer over the Internet. Prior to the program, you will receive a web link to join the meeting. 

The presentation portion of the webinar will last about 45 minutes, followed by about 15 minutes of questions and answers.

Requirements

  • Computer with audio input (microphone) and audio output (speakers) appropriate for your size group
  • TV or projector/screen

The Zoom webinar service EASA uses will ask to install a small plugin. Your computer must be configured to allow this in order to have full functionality. Please check with your IT department or company's security policy prior to scheduling a private webinar.

Private Webinars

EASA's private webinars are an inexpensive way to bring an EASA engineer into your service center, place of business or group meeting without incurring travel expenses or lost production time.

EASA Senior Technical Support Specialist

Concerns about partial discharge (PD) used to be limited to repairers and users of machines rated over 7 kV – and PD was a common consideration for machines rated 11 kV and higher. Since the advent of variable frequency drives (VFDs), PD activity is a major contributing cause to winding failures in 460v and (especially) 575v motors. This paper will describe PD, explain how to detect it, and offer repair solutions.

Topics covered include:

  • Explanation of partial discharge (PD)
  • Description of damage mechanism
  • PWM drive and PD
  • How to evaluate PD
  • Repair tips
