INTERNAL ARC TEST
Low voltage and switching devices (Electric Panels) for factory, workshop, power plants, work places etc. provides the distribution and switching of electrical energy. Low voltage and switching devices (Electric Panels) differ according to their usage and purpose. Low voltage and switching devices (Electric Panels) internal arc condition may occur during use. The internal arc test is a type test intended to simulate such conditions. The internal arc test is a type test based on evaluating the ability of the assembled product to limit its risk of affecting its environment. Internal arc test is a type test for low voltage and switchgear (Electric Panels) produced in accordance with TS EN / IEC 61439-1 and TS EN / IEC 61439-2 standard.
What is Internal Arc Test?
The purpose of performing internal arc testing within the scope of the IEC 61641 standard is to determine the performance under the arc conditions caused by internal error for enclosed units that have completed type tests in accordance with IEC 61439 -1 and TS EN / IEC 61439-2. In this context, the phases are short-circuited by means of a conductive wire in the dimensions allowed by the standard to perform the internal arc test. Indicators are placed around the test specimen in accordance with the manufacturer's declaration during the internal arc test. These installed indicators represent the operator during normal operation. During the internal arc test, in case of internal error, there should be no damage to the indicators around the test sample.
