In the top of tall buildings to install a metal rod, metal wire and buried in the ground a metal plate connected, using metal rods of the point discharge, the clouds brought the power and ground power gradually neutralized. arrester, lightning or energy release and can release energy blackhawks jerseys -voltage power system operation, protect against transient voltage electrical equipment hazards, but also truncated continued flow, without causing short-circuit electrical system grounding devices. Arrester is usually connected between live conductors and ground, insanity workout parallel with the protected equipment. north face denali the voltage over the required operating voltage, the lightning immediate action, flow through the charge to limit over-voltage amplitude, protect equipment insulation; voltage normal, surge arresters and rapid restitution, to ensure the normal power supply.
2 with the electrical grounding earthing grounding why the introduction of the first is to prevent electrical or electronic equipment such as lightning protective measures taken, the purpose is to produce the lightning current through the lightning rod is introduced into the earth , which play a mac brushes role in the building. Meanwhile, ground is to protect the personal safety of an effective means, when the phase due to some reason (such as wire insulation poor, aging lines, etc.) and touch the equipment enclosure, the device's case would have dangerous voltage is generated, which resulting fault current will flow through the PE line to earth, and thus play a protective role.
