FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering. Electrical equipment with metal parts (2) in the housing (1) converts industrial electricity to the desired form. The metal parts (1, 2) are grounded by connecting to the grounding of the output (5) installed on the insulator (4). During operation, pulse interference occurs: parasitic voltage surges, capacitive currents (including in the housing (1)).
EFFECT: due to the magnetic conductors (8), inductance is introduced into the current circuit, which reduces the magnitude of pulse interference in the surrounding space.
