METH sas designs and manufactures electric transformers since 1980 focusing on the quality of its products’ performance thanks to 30 years of experience in the business. Multiple national and international certifications since 1998 are the result of a continuous effort in updating their products to meet the worldwide standards and requirements.

They are specialised in manufacturing single-phase electric transformers from 3,2VA to 80VA and three-phase transformers from 100VA to 630VA, for applications in different fields from industrial, automation, photovoltaic to marine.

Depending on the configuration, METH transformers bear the European and North American approvals such as UL, KEMA and ENEC. Their experience and technology allow them to develop and manufacture new products in a short time to meet any customer’s requests and to improve their products.

METH obtains the transformer parameters that are tested at the end of production such as over-temperature, losses, performance, rigidity, insulation, induced voltage etc using “RALE” calculation programs. During the calculation spacers and cooling channels are properly sized to ensure a long and a reliable service life.

The entire manufacturing process is carried out internally: preliminary controls, automatic winding for small transformers and winding on machine for flat cable, copper or aluminium strip for bigger transformers, core-assembly and soaking or resin. At the end of production all transformers are tested internally with instruments according to ISO specifications and regularly calibrated in SIT centres. METH transformers are 100% tested and test results are stored in METH database and available on customer’s request. METH test equipment allows carrying out all tests required by the standards.

METH Quality System, certified since 1998, rules all the processes: customers and suppliers orders management, preliminary controls, manufacturing cycles, final tests, handling of non conformity. As further confirmation of the constant quality-research over the years, METH has obtained the following certifications:

·UL-CSA for single-phase transformers up to 10kVA and for three-phase transformers up to 25kVA. Meth is the only manufacturer in Europe with UL-CSA LISTED certification

·UL-CSA Insulation System class F and B.

·ENEC-KEMA for single-phase transformers up to 2kVA

·RINA and GL for some single-phase transformers for marine use up to 1Kva

METH have recently embarked on exports and are looking for distributors and agents to help them expand in the African market.
