Frequency content of switching overvoltages
Proceedings of the Institution of Electrical Engineers, 1976Switching overvoltages are usually discussed in terms of their peak values, but their frequency content is also important. The relevant frequencies have now been analysed for certain field-test waveforms as well as for calculated voltage transients that result from energising a single line.

Switching overvoltages in motor circuits
IEEE Transactions on Industry Applications, 2001The switching of HV motor circuits in the megawatt range can cause large overvoltages on motor terminals. The amplitude of the resulting voltage spikes depends on breaker type and circuit characteristics. If the amplitude of switching overvoltages exceeds the basic insulation level of the motor, overvoltage protection circuitry should be installed to ...

Switching Overvoltage Measurements and Simulations—Part I: Field Test Overvoltage Measurements
IEEE Transactions on Power Delivery, 2014This paper presents the work carried out by the IEEE Working Grou[ on field-measured overvoltages and their analysis for validating power system component models to be used in switching transients studies. The work uses measurement data obtained from field tests performed by Bonneville Power Administration in June 1995 where switching overvoltages were

Overvoltages caused by disconnect-switch operation
Electrical Engineering, 1959RECENTLY field tests were performed at the Tanners Creek Station of the Indiana and Michigan Electric Company to investigate overvoltages which were produced when a 1,360-foot section of 345-kv bus was de-energized by an air-break disconnecting switch.1 The high transient overvoltages not only caused severe duty on connected lightning arresters, but ...

Limitation of transmission line switching overvoltages
2010 IEEE International Conference on Power and Energy, 2010In this paper switching overvoltages of an actual transmission line are studied. Simulations are executed using Electro Magnetic Transients Program. A comprehensive switching transient study is performed for the Azerbaijan province network in Iran. The purpose of this study is to determine the unnecessary pre-insertion resistors in the UHV network ...

Switching Overvoltage of UHVAC Systems
2017The UHV system is featured by high voltage level and large switching overvoltage amplitude. The increase of the rated voltage and the decrease of the limit standard put forward more rigorous requirements for the limitation measures for the switching overvoltage of the UHV system, and the preventive measures for the EHV system are no longer completely ...

A Laboratory Equipment for Investigating Switching Overvoltages
International Journal of Electrical Engineering & Education, 1983A detailed description is given of a transmission line model and voltage source suitable for demonstrating switching overvoltages associated with overhead line energisation. The model is 3-phase with the supply electronically switched independently in each phase and incorporating switched closing resistors.

Mitigation of switching overvoltages in transmission lines via controlled switching
2008 IEEE Power and Energy Society General Meeting - Conversion and Delivery of Electrical Energy in the 21st Century, 2008The goal of this work is to present a controlled switching strategy to reduce overvoltages due to transmission line closing and re-closing. Controlled closing and re-closing of transmission lines eliminates the need of pre-insertion resistors, reducing in this way the costs of transmission line circuit breakers.
