Classification of Lightning and Faults in Transmission Line Systems Using Discrete Wavelet Transform

Table 4

Single-line-to-ground fault condition.

Initial variable
Lightning location on transmission line	Voltage angle	Pos_S	Pos_R	Pos_min	Ia_S	Ib_S	Ic_S	Zero_S
30%	0°	13.3318	8.8739	8.8739	8.8806	2.2321	2.2195	0.0893
Compared variable
Fault location on transmission line	Voltage angle	S_A	S_B	S_C
30%	0°	99.4347	24.9921	24.8515
Check variable
Fault location on transmission line	Voltage angle	S_Ph	S_Ph
30%	0°	99.4347	24.8515
Result
Type	lower than 53					Fault
Phase	S_A higher than other phases,4 times					Phase A
