WikiProject Power networks/ZEVS
ZEVS is an ELF-transmitter east of Murmansk used by the Russian Navy to send messages to submarines deep under water. As it operates on 82 Hertz, which is just a bit above power grid frequencies, it looks more a power transmission scheme than a transmitter. In fact, ZEVS uses as antenna two ground dipoles, which are power lines grounded at their end and in which the power to be radiated is fed. They generate together with the earth a loop for the current, which works as antenna.
As ZEVS is from highly strategic importance nearly no facts are published. Nevertheless, its system was mapped on openstreetmap as relation https://www.openstreetmap.org/relation/3407767 whereby some corrections may be necessary.
