Respectively, and after the power cord into the family connected
Lightning protection devices should be installed in the overhead line into the family of a low voltage into the line at the meter and low voltage electrical equipment can produce
electric meter , it is the surge arrester on each pile head into the households, respectively, after the power cord is connected down the pile head is connected to each other
circuit breakers to the ground line arrester. The spark gap
Voltage stabilizer and zinc oxide arrester valve, wiring lines roughly the same, but also a three-phase power supply is connected to the other end of the ground together, lightning meter wiring lines.
