Electricity distribution is done in two stages. Turkish Electricity Transmission Corporation (TEİAŞ) provides electricity to regions through high voltage lines across the country. Electricity distribution companies make the regional distribution of this current, which is reduced to medium voltage in substations. At this stage, the current from the medium voltage lines is switched and transferred to the medium current output lines. The current to be transferred to end users such as home and office is converted into low voltage in a transformer station. Medium voltage level electricity is provided to Organized Industrial Zones and some factories.

The protection relays developed by PAVOTEK are devices for use in power plants distributing over medium voltage lines. Power lines carrying power to these power plants are called medium voltage supply cables (feeders). Feeder lines are connected to systems called cells. Inside the cell  is the breaker, which is an electro-mechanical switch, and a relay that controls this breaker.

The products developed by PAVOTEK are these relays. This relay provides or blocks the transmission of current coming from the feeder by controlling the breaker when necessary. For this, the protection relay monitors the current coming from the feeder it is responsible for and disables the cell in abnormal situations such as high current or high voltage. However, the protection relays are aimed at ensuring the coordinated management of the cells existing in the network, rather than the management of individual cells.
