Arc-flash and arc-flash studies are also clarified. This White Paper also highlights a safety concern when HV/MV switchgear fails catastrophically, particularly oil-filled switchgear assembly. Within IEC Standards, HV switchgear are used on systems above 1 kV up to 52 kV. In North America MV is any voltage between 600 V and 69 kV.
Canada use CSA C22.2 No. 0.22-11 “Evaluation methods for arc resistance rating of enclosed electrical equipment” to evaluate internal arc rated switchgear. Internal arc type testing is very important to reduce the risk of exploding switchgear.
To meet the requirement for comprehensive monitoring of 24 arc flash sensors across multiple switchgear panels, we have identified the PGR-8800 and AFR-4 arc flash protection relays as suitable solutions.
Within IEC Standards, internal arc rated switchgear manufactured prior to 2003 may only have been tested for internal arc in the main MV switching compartment, which was the optional requirements within IEC 60298 (the standard that was superseded by IEC 62271-200).
Our standardized photovoltaic container and energy storage products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
