Correct Answer - Option 1 : Z
1 > Z
2 > Z
0
Positive Sequence Impedance: The impedance offered by the network to the flow of positive sequence current is called the positive sequence impedance.
Negative Sequence Impedance: The negative sequence impedance means the impedance offered by the network to the flows of negative sequence current.
Zero Sequence Impedance: The impedance offered to zero sequence current is called the zero sequence impedance.
The positive (Z1), negative (Z2) and zero sequence impedances of a solidly grounded system under steady state condition always follow the relation:
Order of sequence of impedance is
Z1 > Z2 > Z0
Where, Z1, Z2 and Z0 are positive, negative and zero sequence impedances
