What is quenching an arc? - Standex Electronics

When the reed contacts open they break a circuit. If there is a voltage and current present when the contacts open they will stop the current flow. Once the contacts open the voltage that was driving the current will reappear across the contacts. This is normally not an issue unless the voltage is generally higher than 250 volts. At this level and higher when the contacts attempt to open theyGet price

Application Areas - Arcteq

The AQ-1000 arc quenching system is designed to limit the total arcing time to 5 ms and to minimize (or even eliminate) the damaging effects caused by the arc fault’s temperature and pressure. In most applications this will result in an energy release of less than 1 cal/cm². AQ-1000 is fully reusable which allows for full system testing on site. AQ-1000 is used in conjunction with the AQ-100 arc protection system.Get price

Power distribution | Power Generation and Distribution

In 1930, Siemens introduced a fluid circuit breaker that used water as the arc quenching medium. In this "expansion circuit breaker," the arc that occurred during switching evaporated some of the surrounding water. This caused high pressure to develop, which would cool or extinguish the arc if the flow was designed right.Get price
