Virtual Relay Museum

Hello!
This video channel is dedicated to relays, relay protection and emergency control (RZiA).
On the channel you will get acquainted with the principles of operation of old relays of various types and designs, the history of the relay industry of the Union of Soviet Socialist Republics and countries of the former USSR, as well as other information about relays and devices of relay action.
The video channel is the official channel of the Museum of Relay Protection, on which I post photos and a description of the relay (exhibits) from my own collection. Many videos on the channel are attached to these exhibits.
If you want to know everything about the relay, subscribe to my channel and follow new videos.
I will be glad to any questions on the topic of the relay and constructive criticism.
Your comments and likes will help me grow.

Sincerely, Nikita Lyubimov (collector of the relay)
