Characterisation and Generation of High Impulse Voltages and Currents
Transmission and distribution of electrical energy involves the application of highvoltage apparatus like power transformers, switchgear, overvoltage arrestors, insulators, power cables, transformers, etc., which are exposed to high transient voltages and currents due to internal and external overvoltages. Before commissioning, they are therefore tested for reliability with standard impulse vol...

متن کاملEffect of Humidity on the Breakdown of Air Gaps under Oscillatory Switching Impulse Voltages - Electrical Insulation, 1996., Conference Record of the 1996 IEEE International Symposium on
Experimental investigations were carried out to study the effect of humidity on the breakdown of rod-plane gaps subjected to both uni-directional and bi-directional oscillatory switching impulse voltages. The humidity ranged from 14.1 36 gm/m3 at a constant temperature of 40' C. The gap subjected to uni-directional 6.3, 10, lQ kHz and bi-directional 4.2, 10,20 kHz oscillatory switching impulse ...

متن کاملBearing Currents and Shaft Voltages of an Induction Motor Under Hard- and Soft-Switching Inverter Excitation
Bearing currents and shaft voltages of an induction motor are measured under hardand soft-switching inverter excitation. The objective is to investigate whether the soft-switching technologies can provide solutions for reducing the bearing currents and shaft voltages. Two of the prevailing soft-switching inverters, the resonant dc-link inverter and the quasi-resonant dc-link inverter, are teste...
