Thanks waross. I am confused. The transformers are marked NC 50 one larger than the other and are configured with center taps. The power to the primary comes from two overhead lines.There is no third power line on the pole. The power to the premise is a 4wire labelled black,orange, blue and...
I have researched several configurations used to provide three-phase 240 and 120/240 single phase. Some are V; High leg;and Scott T. It appears that I have the Scott T. However I am not sure since the distribution company stated that they are providing the service with a Delta Y set up.I am...
You have asked the typical question that new engineers ask when approaching a FMEA.
I have tought young engineers that the most effective way of approaching the task is to:
1 ) Identify the energy sources that are used in the product.i.e. how much energy has to support or generate.
2) follow...
Your description of the two transformers providing single phase and three phase capability suggest that the setup is a Scott T distribution used in many old distribution systems.
The Scott system interconnects the secondary windings of the transformers such that one side of the teaser...
