Accuracy of an Icing On-line Monitoring System

An icing on-line monitoring system is designed and produced, by which the humidity, the wind speed, the wind direction, the deviation angel of insulators, the gravity variety of the iced conductor can be measured and sent to the monitoring centre by GSM SMS. The accuracy of above parameters is very important to the application of this device, which are analyzed in details. The running results show that the accuracy of the icing on-line monitoring system is very high, and that this system is an effective method to monitoring the icing status of transmission lines.
