What is an arc flash?

To explain, an arc flash is described as low impedance connections in an electrical system. So as to pass movement of unwanted electric discharge. Vis a vis through the air from one voltage phase to another, or to ground. On the whole, this leads to a rapid rise in temperature and pressure in the air between electrical conductors. With the result causing an explosion known as an arc blast.

Arc blasts and the produced heat can lead to fires. In addition to pressure waves and flying shrapnel that result in serious damage. Under those circumstances, these explosions typically occur without any warning. In effect, destroying electrical equipment fully and lead to severe injury.

What causes an arc flash?

In fact, an arc flash occurs when many electrical conductors are placed close to each other. Rather with significant fault currents flowing through them. In like manner, ionization of the air can take place as a result of various factors. Such as, differences in potential which leads to a low resistance path. And allows current to flow through the air gap between conductors.

In truth, many people assume that low voltage equipment is safe from arc flash. However arc flash hazard levels may be higher at low voltages. Due to the high fault currents. Most incidents that occur in low voltage systems are caused by human error, i.e. a tool slipping while a tech works on electrical equipment.


COBO Electric provides comprehensive arc flash studies. To begin with sending one of our experts to your facility for a full on-site evaluation. Secondly, we do an arc flash modelling. Lastly, we do equipment evaluation relative to the fault current and clearing coordination of your system. Coupled with detailed one-line electrical model drawings.
