6 FAQs about Large-scale Solar Power Generation & Energy Storage
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.
How to evaluate arc rated switchgear in Canada?
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.
Does switchgear pass an arc type test?
Some switchgear is type tested during its design stage to pass an internal arc type test. Switchgear that has been designed to contain the arc should fail safely, thus avoiding risk to operators and preventing lengthy rebuilding time following catastrophic failure, should they occur.
How do I know if a switchgear is IAC certified?
The IAC designations, verified by arc testing, are shown on the switchgear nameplate, along with the root mean square (r.m.s) arc fault current and duration. NOTE: IEC 62271-200 & IEEE C37.20.7 internal arc classifications enables benchmarking testing of switchgear, but it does not guarantee a specific performance in a substation building.
What is an internal arc test for MV switchgear?
For MV switchgear operating above a system voltage of 1 kV and up to 33 kV, internal arc tests are prescribed as an optional type test in IEC 62271-200. A successful internal arc type test, demonstrates that the switchgear can fail in a controlled manner within a designated area of the substation.
Are arc-flash sensors safe?
Sensors available in the market today detect light from an arc-flash inside switchgear very quickly, typically less < 100 ms, and trip the incoming supplies to the switchgear. Some concern has been expressed whether the sensors fail safe. North American Arc resistant testing standards are defined by ANSI/IEEE C37.20.7.
