SPD ကို Ground Point မချိတ်တာတော့ တစ်မျိုးကြီးပဲ။ အဲ့ဒီ Surge Voltage ကဘယ်ကိုသွားရမှာလဲ။ I😅

Great! Thanks. For Myanmar Ctry, we mostly cannot have proper earthing system (0 to 10 ohms). If we do the proper installation to meet the earthing requirement, it may cause about over 50 lakhs. I mean using genuine resistance powder, plates, rods etc. So, sad but in regality, most of houses do not have any earthing system. Among them, we have to use RCCB for protection. So, now at SPD, we have to use earthing connection. It may not feasible for us to do that. Any other alternate method to protect surge issues please. For example RCCB instead of earthing, etc. Thanks.

SPD Is a kind of resistor.It's resistance is very high at normal applied votage.But when very high voltage such as lightenning strikes resistance across SPD very quickly goes down .Therefore voltage across SPD went down to non dangerous level .Refer to Ohms law. V=IR.

SPD က AC ,DC ၂ မျိုးလုံးတွက်ရှိလား SPD အတွက် earthing ohm ကဘယ်လောက်ရှိရမလဲ ကျေးဇူးြပု၍ဖြေပေးပါ
