We have a pole mounted distribution transformer, and I am trying to figure if the X0 should be connected directly to ground rod or should be connected to power panel neutral? One of the arguments made by line crew is that neutral wire should run to main breaker to get good reading between phase...
Hello….. we have 34.5kV distribution lines where we have experienced multiple flashovers on the pole mounted reclosers in past few years. During all failures, we either had damaged interrupters or bottom part exploded. About 70% of the failures happened during Dust storm and raining weather...
What I am bit confused on how would line to ground flashover cause overcurrent on phase conductors resulting in blown fuses and in some cases blow surge arresters?
We recently had few distribution circuits tripped due to very humid weather conditions. Our initial thoughts were air pollutant combined with high humidity, reduced the creepage distance on the insulators which led to line to ground flashovers. However, we found few blown fuses along these lines...
Hello everyone.... Can someone tell me why powerline structures are not designed for the forces due to short circuit currents whereas substation buses design take these forces into account? I have seen some substation gantry designs taking into account the wire loads due to short circuit...
I am wondering if any one went from engineering to research and then transitioned back to engineering? Did you have any issues in getting back into engineering.
I currently work for an engineering firm and have around 10 years of experience in my area. I have an opportunity to work for one of...
