However, it can be noted that noise and voltage breakdown problems will be observed at less than 1/2 cycle. Consequently, modern Static Transfer Switches (STS) have transfer times of 1/4 cycle or even less to avoid unwanted disruptions...

However, losing voltage for only a little more than 1/4 cycle for a computer and/or other extremely sensitive equipment would already cause unwanted disruption", but I don't see anywhere on the curve where it indicates a 1/4 cycle. Instead, it seems to indicate that a complete loss of voltage could be sustained for a 1/2 cycle. What am I looking at incorrectly? <br />Thanks!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9173788893657603698.post-8298883966793355652011-04-23T21:04:14.498-07:002011-04-23T21:04:14.498-07:00Nope...
