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 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, …

High-performance resources

3 test stations are available for checking: • switch making and breaking capacities (overloads) • conditional short-circuit characteristics (with protection) • characteristics of short admissible duration short-circuits (1 second and 3 seconds) • electrical endurances • operating characteristics of protection systems (fuses, circuit breakers, …) • links between different equipment

A service made to measure

Tesla Lab can relieve you of all the administrative steps involved in a large number of certification procedures. It will take care of the contacts with the certification bodies as well as monitoring the procedure through to the obtaining of the certificate.

A set of equipment and services is personally reserved for you to follow your tests in the best possible conditions: camera for monitoring tests with supervisory screen PC monitor giving results in real time fully equipped room: telephone, computer sockets video recording of tests provision of fuses assistance with all your practical organisation: hotel, transport reservations, …

Complete tests
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

(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.
