What is earthing


 grounding the leakage current is called earthing




                                  Importance of neutral earthing
gg 
    gfhg           neutral orthogly matter is important to protect against unbalance voltage ,lightning etc.in the context of arcag ground earth

                      Methods of neutral earthing

1)                        1) Solid earthing
2)                        2) Reaction earthing
3                         3) Resistance earthing
4) Volt                4) voltage transformer earthing

 What is current limiting reactor and it’s disadvantage

Current limiting reactor is used to limit short circuit current when power system is faulty

                               Disadvantage

               1) Voltage drop
               2) Power loss
              3) Power factor decrees
