Check out Tesla Power Lab

Check out the “Tesla Power Lab”, a new technological platform of nearly 2000 m² that has the most comprehensive facilities for a wide range of electrical, mechanical, climatic and functional tests for the development of electrical equipment. The Tesla Power Lab is also accredited by international certification organisations (DEKRA and UL) for carrying out the most stringent certification tests.

Recognised tests

Tesla Lab is accredited by the French accreditation body COFRAC (1) (Comité Français d'Accréditation). It is a member of the l'ASEFA (2) (Certification body for low voltage equipment) and of the LOVAG (3) (Low Voltage Agreement Group) and regularly works in partnership with the international certification bodies: KEMA, CEBEC, UL, CSA, ASTA, Lloyd's Register of Shipping, Bureau Véritas, BBJ-SEP, EZU, GOST-R, …

Temperature rise tests

Three special temperature-rise rooms allow rises in temperature to be measured on the electrical equipment using 72 thermocouples and two central read-out stations. The currents available can reach 6000A in direct or alternating current. The temperature-rise rooms also allow power dissipation to be calculated.

Environmental tests

Tests in dry or humid atmospheres (from -20°C to +180°C), cyclical temperature or humidity variation tests, storage tests up to -40°C, cyclical or resonance sinusoidal vibration and tests thermal derating tests.

Dielectric tests

Shockwave 1.2 µs, peak voltage up to 30 KV, test at 50 Hz, 1 minute, voltage of 1 to 20 KV.

Tests in direct current (DC)

A 3-phase bridge rectifier supplied by one of the 3 platforms allows the carrying out of tests in direct current.

Mechanical tests

Mechanical durability of electrical equipment tests, bending and tensile tests on equipment terminals, tensile or compression tests up to 20 000 N.

Tests on insulation

Extinguishability tests with glowing wire up to 960°C

(1) COFRAC

(Comité Français d'Accréditation) French accreditation body. (Scope of accreditation available on request). Set up in 1994 by the public authorities, the COFRAC provides a means for the laboratories and organisations it accredits to prove their competence and impartiality. Thus it offers companies, consumers and the public authorities a real guarantee of confidence in the services offered by the accredited organisations.

(2) ASEFA (Certification body for low voltage equipment)

Created in 1973, the ASEFA is an independent certification organisation. It makes available to its clients test platforms that today represent the most powerful means in the world in short-circuit capacity. The ASEFA has an independent structure. Platforms linked to the ASEFA by a charter, are accredted by the COFRAC in order to guarantee ultra high performance know-how, absolute neutrality and the total confidentiality of the results. The ASEFA offers 23 platforms belonging to its 9 members (ABB, FERRAZ, LCIE, SOCOMEC, SCHNEIDER, GE Power Control France, LEGRAND, CEGELEC, ENTRELEC).

(3) LOVAG

In a European framework, the EOTC (European Organisation for Testing and Certification) has recognised an agreement group, the LOVAG (Low Voltage Agreement Group) to deal with the mutual recognition of certifications between the ACAE and CESI (Italy), ALPHA (Germany), ASEFA (France), CEBEC (Belgium), KEMA (Netherlands), SEMKO (Sweden), FIMKO (Finland) and ASTA (Great Britain), which are similar organisations. This mutual recognition offers openings at international level.
