Simplified conservative measurements of touch and step voltages
1999 IEEE Industrial and Commercial Power Systems Technical Conference (Cat. No.99CH36371), 2003Protection against electric shock requires grounding systems that must be designed primarily to keep touch voltage (E/sub t/) and step voltage (E/sub s/) to a safe value. Testing of the efficiency of a grounding system is mandatory to verify the capability to satisfy the protection requirements at the end of the construction and periodically in the ...

High Voltage Cables – A Technology Step
Offshore Technology Conference, 2022Abstract A two-sided marked push for subsea power transmission has taken place in the last 5 years, first initiated by the oil & gas industry's push for subsea electrification, then followed by a desire to reduce the CO2 footprint from oil & gas production throughelectrification of production facilities with power from onshore.

Voltage depending load models. Validation by voltage step tests
2006 IEEE Power Engineering Society General Meeting, 2006This paper presents applications of the exponential static load model used to represent voltage depending loads. This model has been used to represent loads of different types: industrial, residential and of petroleum extraction fields. These loads belong to "Sistema Interconectado Patagonico" (SIP), a small power system of 1200 MW of peak load ...

Development of High Voltage Multilevel Step-wave Voltage Source
2018 IEEE International Power Modulator and High Voltage Conference (IPMHVC), 2018With the development of energy Internet, the proportion of modular multilevel converter in the system further increases. High-voltage multilevel stepped waves become a typical waveform stressed on the related insulation. In order to study the insulation characteristics of equipment under multilevel stepped wave stress, it is necessary to develop a high-
