The substation is one of seven substations in the surrounding grid. The grid is separated from the rest of the regional grid and its small size and autonomy has made… Read more
There are two main approaches generally adopted when applying impedance earthing techniques: one NER per transformer unit and one NER per substation serving one or more transformer unit(s). For one… Read more
During the passage of earth-fault current a substation earth electrode is subjected to an earth potential rise (EPR). Potential gradients develop in the surrounding ground area and these are highest… Read more
The objective of this project is to show a method of calculation the amount of incentive and the potential energy savings of distribution transformer in distribution network for Spain. To… Read more
Short-circuit current rating (SCCR) is the maximum short-circuit current a component or assembly can safely withstand when protected by a specific overcurrent protective device(s) or for a specified time. Short-circuit… Read more
