This paper aims to evaluate the electrical tension control in substations through Statistical Process Control (SPC).

For so, it was realized a case study on a concessionaire of electrical Power distribution where they are collected tension  measurements in a substation Through the system of control and data acquisition and using SPSS software to obtain  the control charts, it was possible to evaluate the opportunities for improvement to the voltage levels. In conclusion, this research identifies that, in some periods of the day, the voltage is not in statistical control, being able to provide, through the adoption of specific corrective action, improvements to the substation voltage levels.
