Well here is my quick shot at the answer. Its been a while since I`ve done problems like this so bare with me.
1) Capacitors are opposite to resistors. So add capacitors in series as you would add resistors in parallel.
2) Well if the voltage supply is dc then it makes our problem easy...
Now a better but closely related topic would be the mechanical and electrical effects of a fault on a Power Transformer (similar to a PT but used for power transfer applications). There many configurations of Power Transformers such as: single phase bank, three phase bank, three single phase...
The PT just steps down or up the primary voltage specified by the PTs ratio. Thats it, no more or no less. Nothing fancy about it. No different if you are detecting faults with it or metering for revenue metering or scada but maybe accuracy. Its not a complicated device to model. A more...
The PT is used in conjunction with the CTs to measure the magnitude of voltage and current and their phase relationship with each other. The fault is detected by the inter-relationship of these three quantities. For example line protection detects faults by measuring the line impedance magnitude...
They are also used with the Protective Relaying to detect faults on the power system. They are essential your eye into the system. On systems 230kV and lower, PTs are used as described by dlgoff but on systems higher than 230kV CVT's are typically used which are PTs with the use of capacitors to...
