… lågspänningssäkring, ström-tid-diagramGöteborg Energi AB is a company with high ambitions of maintaining a stable electric distribution grid for the inhabitants of Gothenburg. To maintain a stable grid some safety regulations follows. These requirements must be fulfilled. It has …
… Models of the stations are modeled and analyzed in PSCAD/EMTDC to study the high voltage transients that are created after current chopping with vacuum circuit breaker. Vacuum circuit breaker may chop the current before it reaches zero value, which means that high voltage …
Identifiering av för- och nackdelar med nätstationsmätning, Mälarenergi Elnät AB
… substations that I identified during my master thesis study were the high installation cost of the meters and the increased demand on human resources during the implementation phase. Overall, my economic evaluation of the project showed that the investment was not cost …

… but they may be excessively large during a disturbance. If the voltage is too high it may damage the equipment in the grid and too low voltages may cause problems like voltage instability. The magnitude of the voltage variation depends on the short circuit power capacity of the …
… in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics. During the survey 58 transients was registered, of which 56 was caused from the coupling of IN_PU4040 in HSP01. The additional two transients could not be explained by any event …
