  • #Surge_protection_device_installation (#SPD).
    #Surge_arresters are made for #Electrical_safety and are designed mainly to protect against #transient_voltage surges that appear and disappear in just a few microseconds.
    Although the duration of these spikes are very short, large single surge events such as lightning, can reach some thousands of volts and can cause immediate damage to the equipment.
    These surges cannot be stopped using conventional over current circuit breakers or fuses, since operating time of those switches are not quick enough to detect these fast appearing spikes.
    However, lightning power spikes account for around 20% of total transient surge activities only.
    The remaining 80% of surges occur internally, when a motor starts or some other supply line fault outside of human control.
    Although these surges can be of smaller in magnitude, with a higher frequency of occurrence, and with continued exposure, they can degrade sensitive electronic equipment within the circuit.
    Science behind the selection of SPD Type 1, 2 and 3 for an electrical system, is explained here nicely with simple animation work.
    Installation of an SPD on to an electrical panel board is also explained here in this video.

    Surge ආරක්ෂණ උපාංග නිපදවා ඇත්තේ, මයික්‍රො තත්පර කිහිපයකින් මතුවන සහ අතුරුදහන් වන තාවකාලික වෝල්ටීයතා වැඩිවීම් වලින්, විදුලි සහ ඉලෙක්ට්‍රොනික උපකරණ ආරක්ෂා කර ගැනීමටය.
    මෙම voltage නැගීම් වල කාලසීමාව ඉතා කෙටි වුවද, අකුණු වැනි විශාල තනි සිදුවීම් වලදී, වෝල්ට් දහස් ගණනකට ළඟා විය හැකි අතර, උපකරණවලට ක්ෂණික හානි සිදු කළ හැකිය.
    විදුලි පද්ධතියක් සඳහා SPD Type 1, 2 සහ 3 තෝරාගැනීම පිටුපස ඇති විද්‍යාව, සරල ආකාරයෙන් මෙහි මනාව පැහැදිලි කර ඇත.
    මෙම වීඩියෝව ඔබට ප්‍රයෝජනවත් නම්, කරුණාකර channel එක subscribe කරන්න.
    ස්තුතියි.

    අකුණු ගහන වෙලාවට විදුලිය නැති උනත්,ටිප් සුවිච් එක ඕෆ් වෙලා තිබ්බත් මගේ කාමරේ ප්ල්ග් පොයින්ට් එකෙන් ගින්දර වගේ එලියක් වගේ දෙයක් පිට වෙනවා...ඒකට හේතුව මොකක් ද...මොකක් ද ඒකට කරන්න පුලුවන්
