ZEVS is a facility of the Russian Navy to transmit messages to submerged submarines in deep water using ELF waves. It is located near Murmansk on the Kola Peninsula. As ZEVS works on 82 hertz, it can be only used for very rudimentary transmissions. Due to its extreme low frequency the techniques used by ZEVS are quite different from that of standard transmitters.
The antenna used by ZEVS is a ground dipole. This is simply an arrangement of two widely separated electrodes, through which the transmission current is put in the ground.
As ZEVS is a location of high strategic importance, nearly no official information of the facility are available. Nearly all of the following information were gained with satellite picture, which can be seen on Wikimapia.
ZEVS consists of 2 units, situated at Kolenergo with electricity and have there the designation PS-373 (Cyrillic: ПС-373) and PS-393 (Cyrillic: ПС-393). These Kolenergo substations are designed for transmission ratings of 7.478 MVA and 7.446 MVA respectively, so the whole transmission power of ZEVS transmitter may be between 10 MW and 14 MW, making it the most powerful transmitter in Europe.and at . They are supplied by
The feeder line of the other ground dipole electrode turns from the stations in southwestern direction and then running northward, before they finish at 68.7948802 N 33.6278419 E and 68.7948802 N 33.6278419 E. As there are no traces of ground wires buried in low depth visible, rods running deep into the ground may be used there for the grounding.
