![]() Of course, anyone who comes into contact with the arc flash will also experience electrocution, which can be deadly. Anyone in the area is going to be exposed to extremely high temperatures, which can cause serious burns very quickly. They are most dangerous, however, for those who are in the immediate vicinity of where the fault occurs. ![]() Proper planning ensures that today’s investments will provide lasting value into the future.Arc flashes are dangerous events that can impact an entire facility. Our cable testing allows utilities to easily measure the health of their systems and insure against premature, costly replacements. Other diagnostic tests often apply 150% of the cable’s voltage rating, further stressing the cables and accelerating deterioration.Ĭable deterioration leads to system failure and poor reliability. ![]() Based on the DC Polarization/Depolarization Current Measurement principle, it’s a non-destructive method that applies a maximum of 30% of the cable’s voltage rating. This unique, on-site diagnostic service determines the health of XLPE cables while preserving their integrity. We have partnered with National Research Council Canada (NRC), the Government of Canada’s premier research and technology organization, to diagnose the health of XLPE cables without damaging them. So, for example, if the flash protection boundary is greater than the limited approach boundary then no unqualified person can be permitted in the limited approach area and even qualified workers must wear appropriate arc-resistant PPE.Įnergy Ottawa offers a state-of-the-art, non-destructive cable measurement system for the dependable assessment of medium voltage distribution cables. The arc flash protection boundary and the rules governing access within it take precedence over the shock hazard boundaries.
