AHVAZ, Khuzestan Province -- A student from the Electrical Engineering Department of Shahid Chamran University here, majoring in power, Heidar Ali Raisi, designed and built the first synchro-check device.

The device is applied at high voltage substation switchings and while power houses are being connected to the national network.

Raisi said that the synchro-check relay device is mainly used to check the system's condition and to compare the required set figures before being connected to th e national network and also before switchings at the high voltage substations.

He added, "The electromechanical type of the device currently used in the country has a high wear-and-tear and a relatively low precision, while its switching is some times handled manually which is quite risky.

He said the device is built by using a micro-controller which has undergone test by Khuzestan Province relay experts.

He recalled that research on the device started as of last spring and was implemented once the complete process of its design, writing its software program, setting up its circuit and its final stages was completed in September.
