6 FAQs about Arc flash switchgear in China in Colombia

What is arc flash mitigation?

Innovative arc flash mitigation in less than 4 ms: the highest possible level of arc flash protection for personnel and equipment, maintenance of secure power supply and the reduction of production stoppages.

How to design a switchgear with an internal arc?

When designing switchgear, containing an internal arc is dificult to achieve due to the large energy levels and pressure wave which poses very high dynamic mechanical and electrical stress in the MV compartment under test. Strengthening the compartment with additional mechanical support and thicker diameter metals helps.

Are arc flash and arc-flash studies a safety concern?

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.

What is an arc flash?

An arc-flash (also called a flashover) is the light and heat produced as part of an arc-fault, a type of electrical explosive path. Calculations are carried out to determine the incident energy levels, expressed as cals per cm2.

Is arc rated switchgear IEC rated?

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arc in the main MV switching compartment, which was the optional requirements within IEC 60298 (the standard that was superseded by IEC 62271-200).

What happens if metal-enclosed switchgear is not designed to contain an arc?

If metal-enclosed switchgear is not designed to contain the arc, this can lead to switchgear literally exploding catastrophically and subsequent inferno. Consequently, this can result in fatalities, serious injury, damage to substations and buildings, along with damage to other plant and equipment.
