FIELD: electricity.
SUBSTANCE: technical solution relates to the field of electrical engineering and radio engineering and can be used for protection of the information processed by hardware (HW), computer facilities (CF), computer systems (CS). The information protection device is a three-phase network interference-suppression filter installed in the current supply network, and contains the interference-suppression chokes with coils, capacitors, mutual induction coils, common magnetic circuit, meanwhile the circuitries of the phases A, B, C are connected to the protective line as the low-pass filter elements.
EFFECT: ensuring of information protection from secondary electromagnetic radiations and inductions in a wide range of frequencies participating in the information processing.
