No Joules for Surges: Relevant and Realistic Assessment of Surge Stress Threats
نویسندگان
چکیده
The paper offers a rationale for avoiding attempts to characterize the surge environment in low-voltage end-user power systems by a single number – the "energy in the surge" – derived from a simple voltage measurement. Numerical examples illustrate the fallacy of this concept. Examples are given of equipment for which a failure can be caused by a surge voltage, but with or without relationship to the energy involved in the process.

Internal Protection of Transformer Windings Against Transeint Surges Using ZnO Varistors
Power system overvoltages due to switching, lightning and other disturbances are the main problem for designers of the power transformers. Once some frequencies of the incoming surges match with some of the natural frequencies of transformer winding, the resonance phenomenon is expected in transformer winding. The resonant overvoltages may destroy the insulation between turns and cause to insul...

متن کاملA Mathematical Analysis of Glacier Surges
This paper describes the phenomena of glacier surges and presents a mathematical model based on realistic descriptions of glacier physics, which purports to describe the main features of the flow. The analysis reveals and predicts a variety of phenomena, many of which have been observed to occur, and gives explicit estimates for such quantities as surge front extent, "mini-surge" propagation sp...

Insufficient electrical endurance of equipment and insulation failure against overvoltage is one of the most effective reasons for failure the power line. Lightening, switching or other disruptive parameters can cause line outage or distribution substation failure. There are different devices used to improve the safety, reliability, and power quality of the system. Surge arresters are one of t...

Severe Tropical Cyclones associated with surges frequently hits the coastal region of Bangladesh. For a reliable hydrodynamic model to simulate the severity of such cyclones, it is necessary to incorporate the meteorological and hydrological inputs properly. In order to incorporate the coastlines and the island boundaries properly in the numerical scheme a very fine grid resolution along the co...
