Our company provides the service of data logger calibration as it was recently accredited by the National Accreditation System E.SY.D. (Certificate 547), in accordance with EN ISO / IEC 17025: 2017, for the calibration of instruments measuring electrical measurands.
Our company applies the IEC 61400-12-1 Standard and follows the Power Performance Procedure of the MEASNET network to measure the power curve of wind generators.
It is of a vital importance for all investors to know how their wind turbines perform and this is exactly what a power curve measurement of a wind turbine is all about. It ascertains the relation between the electrical power of the wind turbine and the wind speed at the wind turbine location. The purpose of the measurement is to evaluate the theoretical or warranty power curve of the wind turbine.
Our company is accredited according to EN ISO/IEC 17025:2017, for the calibration of cup anemometers, uniaxial propeller anemometers, hot wires / hot films as well as sonic anemometers.
Our company is accredited according to EN ISO/IEC 17025:2017, for the calibration of wind direction indicators including wind vanes or sonic instruments in the wind tunnel of the National Technical University of Athens. The cross section of the wind tunnel used is 1,4 m * 1,2 m and the instrument under test is rotating at a fixed speed of 0.50 ° / s by a controlled stepper motor.
Our company is accredited according to EN ISO/IEC 17025:2017 for the calibration of thermometers in the range of -20 to +90 °C.
A bath of controlled temperature and constant stirring is utilized to achieve best stability and homogeneity of the fluid in which the thermometer under calibration and the reference thermometer are immersed.
Our company is accredited according to EN ISO/IEC 17025:2017 for the calibration of barometers within the range of 500 to 1100 hPa.
Our Laboratory of Renewable Energy is accredited to EN ISO / IEC 17025:2017 by the National Accreditation System (E.SY.D., certificate number 547) for carrying out wind potential measurements, which are essential for the selection of the wind turbine type to be installed and the prediction of the wind energy yield.
The wind potential measurement includes:
