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.

Power factor: What it is, why it's important

Power factor can be best explained with a short illustration. Figure 1 below shows the three ele­ments to consider. First, true power, measured in kW, is the power that does useful work. Reactive power, measured in kVAR, is the power that is stored and returned by all inductive machines, such as motors and transformers. The apparent power, measured in kVA, is the voltage multiplied by the current in the system. Even though the true power is doing the work, the power company has to dis­tribute the apparent power.

Mathematically, the power factor is the cosine of the angle between the true and apparent power. Power factor is defined as the ratio of true power used in an electric circuit to the apparent power, or the power that is apparently being drawn from the source. In a sense, apparent power is “bor­rowed” from the power company. Since AC power is continuously reversing, the borrowed power is sent back to the system every time the al­ternating current reverses.
