New Services:

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 cover 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.
