Popis 230 V power grids Protection (3)
AC circuits pose a double threat. First of all, acoustic data can be leaked through the AC circuit (230 V). And secondly, there is a threat of information signals leak from office equipment.

There exist passive and active techniques for AC (220 V) protection against unauthorized data retrieval.
Passive 220 V circuits protection implies using anti-interference line filters. Such filters weaken any signals in the frequency band of 0.01-1,000 MHz with the efficiency of at least 60 dB and, thus, do not let the information signals generated in office equipment get through. Besides, a correctly installed filter also protects office equipment from the harmful effect of external interference. It's worth mentioning that efficient operation of anti-interference filters requires high-quality grounding.
Active AC circuits (220 V) protection techniques imply generation of a noise signal exceeding the information signals and signals of information retrieval devices in level by special generators. Such noise signals are supplied to the 220 V circuit and to the ground circuit. These generators produce noise for 220 V circuits and ground circuits.

Active AC circuits (220 V) protection Is an information security device that is designed to actively protect informatization equipment against information leaks through the power grid and ground system. The Product provides protection against data leaks through the 220 V single-phase three-wire power grid with the frequency of 50 Hz by generating broadband noise interference in all the masking interference conductors in power supply and ground circuits in the frequency band of 0.01 – 1,800 MHz.
