Canada use CSA C22.2 No. 0.22-11 “Evaluation methods for arc resistance rating of enclosed electrical equipment” to evaluate internal arc rated switchgear. Internal arc type testing is very important to reduce the risk of exploding switchgear.
Arc-flash and arc-flash studies are also clarified. This White Paper also highlights a safety concern when HV/MV switchgear fails catastrophically, particularly oil-filled switchgear assembly. Within IEC Standards, HV switchgear are used on systems above 1 kV up to 52 kV. In North America MV is any voltage between 600 V and 69 kV.
The AQ 100 series arc flash protection relays provide trip times of 27 ms. When combined with a fast-acting circuit breaker, a total clearing time of 5 to 8 cycles is achieved. Protection schemes can be based solely on an arc light signal or on arc light and overcurrent signals occurring simultaneously.
The main purpose of arc flash protection in a substation is to protect both personnel and equipment from the consequences of an arc fault. Arc flash faults are the most devastating types of faults known in power distribution systems.
