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

How Arc-Quenching Switchgear Improves Safety | Pumps Systems

Passive ProtectionActive ProtectionCurrent-Limiting Arc-Quenching SystemsConclusionSince the introduction of arc-resistant electrical equipment, the design paradigm has been to create a method of containing the energy from an arc flash event and redirecting it away from the operator. These methods typically include heavily reinforcing the electrical equipment enclosure using thicker-gauge steel, reinforced hinges and multipoint door latches to contain the arc energy and prevent enclosure fragmentation and burn-through. Mounted on top of the gear, plenums connected to ducts serve to redirect the arc gasses through the top of the equipment and out of the room. Such designs benefit from simplicity and acquisition costs. These passive arc-resistant designs require no electronics or electrical power to function. Minimal technological advancements were required to develop these designs. All that was needed was a more robust equipment enclosure. The incremental costs of such arc-resistant equipment remain relatively low, requiring only the addition of more steel and more...Get price

Radio in the United States - Wikipedia

OverviewForeign Language BroadcastingCall LettersHistorySee AlsoFurther ReadingRadio communication in the United States is regulated by the Federal Communications Commission(FCC). Under its oversight a variety of broadcasting services have been developed, including: 1. AM band: When radio broadcasting first became popular in the 1920s it was primarily within what is now the AM broadcast band, which spans from 540 to 1700 kHz. The AM band continues to be used, with the most powerful clear-channel stations granted a coverage area of hundreds of miles from its transmitter at night, when atmospheric conditions carry AM signals far longer by reflecting signals that would otherwise head into space back to Earth. Less powerful stations share frequencies and may either shut down, drastically reduce power and/or dramatically change its directional pattern to avoid interference at and near sunset, flipping back at sunrise. Before television, AM radio was the predominant broadcast entertainment medium in America. Beginning in the 1970s, AM listenership has significantly...Get price
