High Voltage and Metrology

LCOE’s High Voltage and Metrology activities are integrated into the High Voltage Technological Centre (CTAT), which is configured as a support tool for industry and R+D+i in the electrotechnical field.

Its structure, personnel, and facilities, together with its experience, prestige, national and international accreditations, and recognitions, make it an international reference in High Voltage and Metrology.

The services it offers include testing, both in its own facilities and on-site, metrology and R+D+i.

High Voltage Calibrations

LCOE’s High Voltage electrical calibration laboratory, accredited according to ISO 17025 by ENAC, is the depository of national high voltage standards. Its international recognition, as a Designated Metrological Institute, allows it to issue BIPM Certificates to disseminate the traceability of high voltage direct, alternating and impulse voltage quantities. The recognition of the LCOE by the Administration as a Verifier of Electrical Measurements for Voltage and Current Transformers allows it to also issue Certificates of Verification at Origin.

Insulation diagnostic and on-site testing

LCOE has different mobile test generators, some of its own design and development, for conducting on-site tests of high voltage equipment. Partial discharge measurement is used to diagnose insulation.

The measurements are carried out in the tests prior to the commissioning of the equipment (off-line techniques) and also during their normal operation (on-line techniques).
