Abstract
The efficiency of ground short-circuiting the damaged phase of the network to the ground is analyzed in the context of finding ways to increase the electrical safety of mine site 3.3 kV power network operation. In the context of ensuring human protection from electric shock, the expediency is justified and a technical solution for post-commutation pulse phase short-circuiting in the reverse EMF circuit is provided for the asynchronous motors of the power consumers within a technological mine site.
