Hi,
I am busy with a project to install new switchgear to supply two 2500HP, 6300V Synchronous Motors. As part of the project I thought of including a motor protection relay to provide stator protection for the motors, to complement the Multilin SPM (Synchronous Motor Protection) relays...
Hi,
What is the maximum voltage that can develop across the contacts of a three phase circuit breaker? This may seem like a trivial question at first but please give it some thought. Assume the circuit breaker feeds a load from the secondary side of a three phase, 11kV/550V, delta-star...
Hi,
Does anyone know how to quantify the effects of an o/head power line running adjacent to a pipeline? I have heard that the power line can change the corrosion patterns of the pipeline. I am busy designing an overhead line and was hoping to run the servitude adjacent to the servitude of...
I would appreciate any information on motor protection, right back to the basics.
We have recently blown our second 220kW, squirrel cage induction motor in a slimes pumping operation. We have three pumps running in series to generate the required pressure head. When the slimes settle it is...
I am experiencing polluion flashover problems across substation bushings and line insulators. The HT components are situated in a mist belt, on the coast, in a dry windy, semi desert environment - certainly not the best conditions. I am considering "live" spray washing but am...
