Single-phase inrush current damping reactors for medium voltage capacitor protection
Single-phase air-core reactors EDD are intended for work in indoor medium voltage compensation system. They limit the starting current during the start of the medium voltage capacitor bank, thus protecting the circuit elements from overload. The construction of the chokes enables natural air cooling and ensures a correct operation in horizontal and vertical position.
