10,000 tests per year
29 March 2022
IN THE municipality of Saint-Bonnet-de-Mure global expert in electrical power, Mersen, runs a test lab which carries out approximately 10,000 electric, dielectric, mechanical and environmental tests, primarily on fuses and fuse gears, such as those that protect semiconductors, cables or motors. The test centre is accredited by France’s COFRAC and in accordance with the ISO-17025 standard.
The High Power Test Lab tests the short-circuit properties, transient current withstand, switching on and off under voltage and in case of short circuits, as well as operation under fast current rise conditions – with both alternating and direct current. Testing of short-circuit properties involves the use of the center’s extensive optical equipment, with high-speed cameras that can record up to 40,000 images per second.
The Environmental and Low Voltage Test Lab is equipped with seven environmental climatic chambers for testing of components under extreme environmental conditions associated with cycling power supplies. They can generate temperatures from -40 to +200˚C and relative humidities ranging between 0 and 99%. The environmental test chambers can also simulate accelerated long-term aging processes.
