Nettet8. aug. 2024 · Normally, with delta, you use some bias transformers to create a “center ground”. So at 240V you have around 137 volts to center. Normal enough. However, … Nettet3. nov. 2024 · Introduction - Single line to ground faults are the most common type of fault in a power system. On overhead transmission and distribution lines, these are often caused by a tree branch coming into contact with a power line and the fault is typically intermittent. On industrial systems, these kinds of faults are commonly caused by a …
