Please Read Carefully... I Am Live In China... So No GFCI/RCD/RCCB/RCBO or Equivalent Is Mandatory, and There is No Anything GFCI/RCD/RCCB/RCBO or Equivalent Is Installed In My System, From Utility Is There Only Two Wire, Neutral and Phase, Transformer That Feed My Home Is Single Phase, and Only Supplied My Home
My Ground Rods Is 3 meters deep, 1.5 meters under soil surface, soil water is normally only about 70cm under surface, distance from my ground rods and utility transformer ground rods is about 250 meters, electricity is one phase 220v 100a
My Question is :
Why Smart Meter MCB is tripped when ground fault occurs ?, Is That MCB at Smart Meter is Not Good ? or My Ground System Is Very Good and Resistance Between Ground Rods In My Home and Ground Rods In That Utility Company Connected At Transformer Neutral Is So Small ?
