Description

The Electric Metrology Lab (LME) began operating in 1983 and was, at the time, the only reference point in the area for electric magnitude metrology and calibration activities.

The LME complies with all the specifications set down in UNE-EN ISO/IEC standard 17025. In 1997 it received accreditation by the ENAC (Spanish Accreditation Body) for direct cu- rrent and low frequency electricity. In 2007 it went on to receive accreditation to perform measuring tests on Wind Turbines and Distribution Networks. The full range of its accredi- tations can be viewed on the ENAC’s website (www.enac.es).

A High Voltage section has recently been added to the list of services offered by the LME. Its main activities include:
  • Dielectric tests on equipment used for protection against electrical ha- zards, such as gloves, hot sticks, no-voltage detectors, insulation mats and blankets.
  • In situ calibration of high voltage dividers and generators.
Lines of research:
 
As regards research strategies, the follo- wing fields are the main working areas:
  • Implementation of the national grid quality model.
  • Measuring and detecting events using advanced analysis and calcu- lation algorithms.
 
Services offered
 
Calibrations department:
 
The LME is an ENAC accredited calibration laboratory, granted accreditation number 67/LC119 to carry out electricity calibrations both in the permanent lab and in the client’s facilities (known as in situ calibrations). The following electric magnitudes are calibrated:
  • Direct and alternate current voltage.
  • Direct and alternate current intensity.   l Direct and alternate current resistance. lActive,reactiveandapparentpower.
  • Basic grid quality parameters (only accredited laboratory in Spain).
Testing  department:
 
The LME is the only testing laboratory with ENAC accreditation number 581/LE1265 to per- form measurement tests on wind turbines and distribution grids. It also boasts accreditation by Measnet to perform power curve tests on wind turbines.
 
Accredited measurement tests include:
  • Wind turbine power curve testing and calibration of the test area according to IEC/UNE- EN standard 61400-12-1, with accreditation by ENAC and Measnet.
  • In situ grid testing by means of Class A analysers according to IEC/UNE-EN standard 61000-4-30 and UNE-EN standard 50160. The following parameters are measured: frequency, voltage range, flicker severity, temporary power surges, voltage dips and in- terruptions, voltage and current harmonics and interharmonics up to the order of 50.
  • Measuring voltage dips and electrical response in wind turbines according to operating procedure PO12.3 of the Wind Power Business Association (AEE for its Spanish initials).
  • Testing and validating component simulation models according to operating procedure PO 12.3 of the AEE
