In the corona discharge detection system for electric power equipments, we propose suitable control method for the application of efficient wireless sensor networks. It is the POSIX standard lightweight thread which is each TCP and RF transceiver function for minimize load on the system. In addition, we have applied for mutual exclusion technique to the program, the data transmission rates increase and the prevent collisions between the data communication. The program consists of a clustered END nodes and the FRONT-END node that lab test was performed.

In this paper, we present the development result of UV optical filter which is used in detecting systems for occured corona discharge within electric facilities. Fault symptoms are occured with electrical wave, ultrasonic wave, temperature and air discharge. In these ways, we choose the air discharge phenomenon. Corona air discharge can easy observed by solar-blind band pass filter. Therefore we present the solar-blind optical filter applied with various coating technologies.
