The product is a high impedance bandpass filter, a parallel RLC circuit. The inductive reactance opposes the circulation of the current, its value depends on the frequency of the current and the capacitive inductance depends on the coil and on the material used for the core.
In our system it is interposed, connected in series, to the earth conductor (down conductor) of the protection system against direct and indirect atmospheric discharges or to the conductor entering the general electrical panel deriving from the dispersion circuit.
They consist of a semiconductor element, commonly formed by a cartridge containing a more or less compact granular mass of crystalline semiconductor material and piezoelectric and/or pyroelectric material.
Inside the "filter-block" there is also a shunt element, connected in parallel to the semiconductor element.
This product is also used where it is necessary to maintain a substantially negligible impedance at the mains frequency, such as for example in the grounding (sea) of electrical systems. In fact, our lightning protection systems envisage the use of block filters between the sea and the grounding (sea) conductors of the electrical distribution system of the boat to be protected, opposing the onset of potential differences between the different electrically rigid masses hit by shock fronts of very high frequency electromagnetic energy, carrying out an inhibition action when critical conditions of pre-lightning or lightning formation occur, of course we mean the ascending type.
The filters are available in different sizes, these depend on the conductor section of the existing grounding (sea) system.
