Use of quenching device reduces the calorie/cm2 energy release typically to less than 1. The main purpose of an arc flash protection is to protect both substation personnel and equipment from the consequences of and arc fault. An arc protection system detects the fault in less than 2 ms and including the delay in the breaker the time for extinguishing the arc is normally less than 70 ms. A normal selective over current protection can have operation times up to 500 ms. In case of an arc fault in a switchgear equipped only with traditional feeder protection, the risk for severe injuries to substation...

ARCTEQ INNOVATION: Re-usable arc quenching device according to IEC 60947 and UL 2748 ARC FLASH INCIDENTS Arc flash faults are the most devastating types of faults known in power distribution systems. Arc flash incidents in medium and low voltage air insulated switchgear and control gear are known to cause annually a number of fatalities and personal injuries, mainly by 2nd degree and higher burns. Arc flash faults cause also severe equipment damage leading to time consuming repairs and extended power outages. Arc flash has been greatly researched in the last decade and standards such as IEEE...

Standard arc scheme layout for medium voltage switchgear with two incoming circuit breakers and a tie breaker.

ARCTEQ INNOVATION: Adding pressure criteria in the arc flash protection BACKGROUND The first generations of arc flash protection relays utilized light sensitive arc sensors alone as the tripping criteria. Advances combined arc light and current sensing for the dual sensing method to further increase the reliability of the protection system. However, the traditional current and light-based dual sensing system may overtrip when installed in equipment involving air magnetic circuit breakers. As well in some cases, especially in low voltage systems, the absence of current transformers makes it practically...

AQ-110P is a sophisticated microprocessor-based arc flash protection unit with combined current and arc sensing. When the AQ-110P detects an overcurrent in the incoming feeder and a light signal from a sub unit or a direct light sensor, it minimizes the damage caused by an arcing fault (arc flash) by tripping the circuit breaker sourcing the fault current. The AQ-110P complete system self-supervision function provides the highest level of dependability by continuously monitoring all internal system functions along with external connections. MEDIUM VOLTAGE PRODUCTS ORDER CODE AQ-110P - X X X X Auxiliary...
