If suddenly someone throws a pounce on the high-voltage line, or a bird gets into the wires, the high-voltage line is immediately turned off. But I'm sure you didn't know that it turns back on in a split second.
This is called automatic reclosing (AR) and refers to automation and power systems.
Why was it created?
Automatic reclosing has been designed to restore power supply in the event of transient faults.
What is volatile damage?
Let's say a tear of wires, a bird that blocked the insulators of a high-voltage line, or someone made a "throw". In the event of a short circuit, this damage is eliminated by itself - the bird burns out, the "throw" burns out well, or the splash of wires is eliminated.
To quickly restore the power supply, the line is re-energized by means of automation.
Legend about APV
There is a legend that automatic reclosing was invented under Stalin. Legend has it that once at a distant power plant, an engineer on duty saw how a high-voltage power line to large enterprises turned off and then he calls himself Comrade Stalin says:
- "Dear comrade, why did your plant shut down?"
And the engineer answers him:
- "yes, nothing turned off, he took it and turned it back on and the line became energized"
This is how the automatic reclosing was invented in a simple manual way.
I emphasize, dear readers, this is just a legend. There is no confirmation of this fact :)
