FIELD: electricity.SUBSTANCE: consumer (4) is protected by protector (S), at that it is possible to set operating value, in particular, operating current of protector (S). The installation includes control unit (1) to which value of measured current is delivered for current consumed by the consumer (4); at that depending on characteristic of the measured current value control unit (1) generates limit value (G, G) transferred to protector (S) in order to set operating value. Thus control unit (1) allows instant matching of operating values, especially operating current, with actual operation conditions.EFFECT: improving reliability.23 cl, 9 dwg |
