Subject: | HFE/MET/M1 - Induced voltage on wind speed sensor cable |
DataStreams: | hfemetM1.b1 |
Description: | The cable for the wind monitor is not a twisted pair shielded cable. This caused an induced voltage on the wind sensor wires from the wind direction measurement excitation voltage. A small offset is added into the wind speeds. This value varies. Most frequently the values of 0.49, 0.588 and 0.686 m/s were added into the wind speed. On 11/27/2008 the value jumped to 0.98 m/s for most of the day. |
Suggestions: | Check the calm wind speed values for the days being used and subtract them from the wind speeds to get the accurate wind speed values. |
