Abstract

The construction of an electronic system for the overvoltage and undervoltage protection of an industrial power distribution network is described. It is a logic circuit with an electromagnetic connection to the network that turns the circuit breaker off when the voltage fluctuations to the load range +10%. The circuit works in low voltage values, construction cost is negligible, the energy consumption is unimportant, and the life duration of the electronic parts is quite long. The device is useful for the protection of industrial electrical installations
