This webinar is taught by Edward Uftring, Consulting Engineering Specialist at ABB. He will be presenting on the fundamentals of breakers, their applications, and the electrical standards they must conform to. There will be detailed overview of breaker components, ratings, operation, selectivity and mounting.
Excelent explanation. Thanks for sharing.
Thanks the upload, very useful and concise information 👍
This is very good and informative but something should be done about the sound quality. By the way, do you mean "voltage drop" when you say "power drop"?
Thanks for the information. Could you please explain how the timer works on an electronic breaker. is it counting cycles or does it have a counter inside?...Thanks...
Depends on the breaker. Some circuit breakers have the ability to measure the zero cross of the phase and then will open based on number of zero voltage on the incoming phase. They will then open as close to zero crossing as possible. Other will open regardless of timing, i.e instantaneous, and will open immediately. In this case the breaker’s contacts are tested to that full fault.
Is wye grounded primary and grounded wye secondary a separately derived system?
What is the lugs temperature rating of IEC Breaker?
The sound is very bad. I can hardly hear what he said. Fortunately there are power point. I wish he had a mic.
terrible audio but good info
some of our older videos have less than optimal audio because we work with people all across the globe. Sometimes out of our control. But thank you for watching. Most of our new videos. dont have any audio issues.
I need instraction prekar
That audio quality is awful.
I wish this guy would stop staying "pop." Breakers don't "pop" they trip.
