Electrical Equipment

Conformity assessment of electrical equipment is generally required by the final users according to particular contracts with the manufacturer or by the market in general. CESI certifies the conformity assessment of electrical equipment as an accredited certification body according to standard ISO/IEC 17065 based on tests performed in CESI Group (CESI, FGH, IPH) laboratories or in other laboratories under CESI witnessing. The CESI conformity assessment process refers to the CESI-HV Certification Scheme for high voltage (>1000 V) electrical equipment as well as to the CESI-LV Certification Scheme for low voltage (< 1000 V) electrical equipment.

What we do

CESI can produce Certificates of type conformity, as Certification Body accredited by Accredia, according to the Standard ISO/IEC 17065​; Certificates can refer to national or international Standards or to Technical Specifications of final users (e.g. ENEL, TERNA, EDF, AENOR, KAHRA-MAA, DEWA, etc.). The certifiable electrical products are the following:

​Product Group
High Voltage equipment
Switchgear (A.c. circuit-breakers >1000V,A.c. switches >1000V, Disconnector and earthing switches >1000V,Switch-fuse combinations >1000V,A.c. contactors >1000V)
Fuses (Current limiting fuses, A.c. expulsion and similar fuses)
Enclosed switchgear and controlgear (Gas-insulated and metal-enclosed switchgear and controlgear, A.c. insulation-enclosed switchgear and controlgear)
