Large transformer relay protection based on the ratio of induced voltages;

Hazard of induced voltage in isolated-neutral power supply system of aluminium smelter and its elimination;

Emulation and study of induced voltage and current for 500 kV double-circuit line on same tower;

Problems of induced voltage and current for 500 kV enhanced interconnection systems between Fujian and Zhejiang;

To reduce the inductive voltage,shield cable is proposed,or connecting parallel capacitor to power-supply line temporarily.

The inductive voltage and inductive current of 500 kV double-circuit transmission lines were calculated and measured on site.

To avoid the influence of the running ways and faults of power system on OPGW and to ensure its regular running, a measure that install composite impedance in OPGW to keep the inductive voltage and current of OPGW within the allowable range is presented in this article.

Calculation of the induction voltage on double circuit transmission lines;

Results show that there exists a perfect corresponding relationship between the induction voltage and the carburized depth.

This paper calculates the induction voltage and current of double-circuit transmission line on same tower in 750 kV xining-Yongdeng-Baiying project by EMTP.

A digital simulation technology for over-voltage induced by lightning strikes on extra and ultra high voltage towers is presented,including the mechanism of the induced over-voltage and the design principle and process of the simulation program.

As the development of power system, especially the constructing of UHV transmission including AC 1000kV and DC 800kV, the formula for calculating lighting induced over-voltage commended by the national electrical code is no more appropriate now.
