Inductive Voltage Protection of Tension Stringing for ±800 kV JinSu Transmission Line
In the view of the higher inductive electricity during the tension stringing at the package section in the process of the ±800 kV DC ultra-high voltage of Jinping to southern Jiangsu transmission line project, by establishing the inductive electric model and the simulation calculated under the condition of JinSu two polery line wires respectively impended above 2 m and 28 m high, the results are 5. 032 kV （2 m） and 55. 436 kV （28 m）. Combined with 800 kV JinSu transmission line project＇s characteristics and the experience of using special grounding tools, formulated the anti-faradism technical measures and operation requirements, which have gotten good effect and ensured the safety of construction workers and equipments during the tension stringing.
