| Abstract: | The computation of induction current of short distance, non conversion 500 kV lines on same tower under various operating conditions by means of EMTP program is described through the computation of induction current of Yangzhou No.2 Power Plant Jiangdu 500 kV lines on same tower showed that the existing grounding switchgear at both side of the line will not satisfy the requirement for open and close of the line during maintenance. |
