FIELD: electricity.
SUBSTANCE: device (10) for control of voltage suppressor contains: a ground line (23); a measurement unit (24) comprising one or more analogue measuring circuits (25, 26) for measuring an electric current passing through the ground line (23); an electronic processing unit (43) for receiving measurement signals from the measuring circuits; a storage medium (44) for storing control data generated by the processing unit; a main module (20) that accommodates the ground line and the measuring unit; and an auxiliary module (40) that accommodates the processing unit and the storage medium, and is removably mounted on the main module. When an auxiliary module is installed on the main module, components are connected to each other using connectors (29) on the main module and the corresponding socket (49) provided for in the auxiliary module.
EFFECT: providing the possibility of maintenance without interrupting power distribution.
