The most likely time for an arc fault to occur in a switchroom is during electrical and mechanical operations, such as switching, isolation and racking of circuit breakers. It is common practice in the industry to use personal protective equipment (PPE) for operator protection during these operations, however it is more effective to isolate the operator entirely from the arc fault hazard. Isolation involves personnel being separated from the energised electrical equipment and conductors.
NHP's TemRack iR is a fully integrated automated motorised racking device, which enables remote racking of the Terasaki TemPower 2 AR ACB body in and out of its associated carriage. The automated racking function permits safe isolation of the ACB with zero physical interaction between personnel and the ACB, thereby reducing the risk of exposure to explosive arc fault events and high incident energy.
