Sandia Expertise Guides New Photovoltaic Requirements

Sandia’s Photovoltaic (PV) Arc-Fault Detec­tion and Mitigation team has gained worldwide renown as a leader in the science of PV arc faults. As a driver of groundbreaking experimental and numerical simulations in this area, codes and standards bodies have called on Sandia to improve requirements for arc-fault cir­cuit interrupters. Sandia

  • has advised the National Electrical Code making panel on changes to the 2014 require­ments,
  • is working closely with Underwriters Laboratories to refine the U.S. PV arc-fault circuit testing requirements, and
  • is collaborating with the International Electrotechnical Commission to establish an inter­national arc-fault circuit interrupter standard.

    These photographs show the nature of the damage an arc fault can cause.
