Testing Arc Flash Rated Switch Boards

With the introduction of built-in Arc Flash protection for switch boards that manufacturers have introduced, traditional methods of detecting internal PD have become ineffective to accurately detect. To over comer this, HVS in 2010 have undertaken considerable R& D and developed a process in conjunction with the very latest PD advancements developed both in the United Kingdom and United States to accurately detect this internal destructive PD & its location that may lead to switchboard failures. Industry have introduced new requirements on the correct level of protection required. An a example of this is shown below.
