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

  • Internet connection
  • 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.

Effect of voltage variation on induction motor characteristics

What is voltage variation? Voltage variation is the deviation of voltage from the rated voltage; NEMA MG1 Section 12 allows a plus or minus 10% variation from rated voltage. That rat­ing assumes balanced voltages and acknowledges that motor performance will not necessarily be the same as at rated voltage.  Note: The tolerance for voltage unbalance is only 1%, an order of magnitude less than the 10% voltage variation tolerance. For more informa­tion on this subject, see the December 2007 edition of Currents for an article on voltage unbalance titled “Unbalanced Voltages and Electric Motors.”
