Blowout coils may be used to extinguish the arc by means of a magnetic blast. The
arc created when the contacts open is subjected to the action of a magnetic field set
Medium-voltage motor starters use up by coils connected in series with the circuit being interrupted.
blowout coils. What do these do? These coils are called blowout coils because they help blow out the arc
magnetically. The arc is magnetically blown into arc chutes where the arc is
lengthened, cooled, and extinguished.

NFPA 70 (NATIONAL ELECTRIC CODE) protective devices
Two standards are typically used for the IEEE C37.1
interconnection of smart devices in a IEC 61850
substation environment. One is an IEC
standard, the other is an IEEE standard.
What are the two standards?
Time travel analysis is commonly is used on medium and high-voltage circuit breakers and provides information as to
