This Tec Automiser Synchroteq Plus Programmable Controller is used to increase the stability and reliability of HV transmission lines. The controller decreases the stress on electric network and switch gear which uses high voltage. Synchroteq Plus ensures low maintenance and enhances the service life of an expensive equipment. This unit is operated with a Smart Coding sytem that specifies the exact product configuration. It eliminates stresses on HV equipment and disturbances on power lines when performing switching loads of HV capacitor banks and HV shunt reactors since they ALWAYS perform switching operations at the right instant. In addition, It takes into account the effect of fluctuations in operating variables (temperature, pressure, auxiliary voltage, idle time, etc) to predict the breaker's time operation, ensuring an optimal performance over a wide range of operating conditions.
