Other arc flash protection methods employed by arc resistant switchgear include, but are not limited to, the following. Workers who maintain and operate the switchgear must also wear the proper Personal Protective Equipment (PPE), which includes arc-rated clothing, gloves, face shields, and other gear.
Switchgear arc protection mainly involves the use of vents and duct system to carry away the super-hot gases and high pressures of an arc flash away from the switchgear enclosure and to a safe location. This can be in the area above the switchgear or outside the switchgear room.
Arc resistant switchgear is designed with different arc mitigation capabilities as defined by the ANSI standard C37.20.7. Based on the standard, arc resistant switchgear types include type 1 and type 2. These offer varying accessibility features. Type 1 arc resistant switchgear is accessible in the front only.
Generally, this type of switchgear will come with flaps that open under the intense pressure of arcing energy. The flaps allow the heated gases of an arc flash and the pressure to safely vent out of the enclosure and away from the operator. When venting arc flash gases outside of the switchgear room is necessary, extra duct work is used.
An arc flash happens when current travels through ionized air. It's usually an attempt by the current to move from one conductor to another. When this happens, an immense amount of energy is released. The energy of an arc quickly converts into visible light and extreme heat. The heat makes the air to expand almost instantaneously.
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.
