Nowaday's Power Cable [2010-12-01]

Transient over-voltage damage to the controlled equipment Generally, pumping station design and construction of protection for the cloud-to-measure have been more perfect. Most automated systems being placed in pumping station structures, network cable, power cable laid on the cable channel, which suffered a direct lightning strike is unlikely.

BVV Cable

According to lightning electromagnetic pulse (LEMP) and practical experience shows that: computer and other automated systems equipment damage is mainly due to surge voltages caused by lightning sensor. Lightning induced surge voltage is generated in microseconds to milliseconds between the peak impulse voltage, the transient over voltage. It can be through the power cord, Antenna, communication lines and signal lines to the introduction of induced surge voltage wave inside the device, respectively, damage to the power supply module, communication module, I / 0 template, resulting in equipment malfunction generated, temporary paralysis or burning components immediately .
