Secondary.
I think you mean 'winding', rather than 'phase'? The cross-sectional area of the conductor must be such that it can carry whatever current the winding is designed to carry -if the current is low, then the cross-sectional area (and, hence, its thickness) can be low.
The higher-voltage winding has more turns (therefore its conductor will be longer) than the lower-voltage winding and, because it will carry less current, its conductors will have a lower cross-sectional area. Consequently, the higher-voltage winding will have a higher resistance than the lower-voltage winding.
"Torroidal" means donut shaped; a torroidal transformer is one where the core forms a circle. Typically the transformer is placed around a conductor, which is considered the "primary winding" with 1 turn. The secondary winding is the copper wrapped around the circuilar core.
the basic difference is ,in short shunt motor the series field winding wont carry any current under no load condition whereas in long shunt motors series winding will carry no load current.....
A Linear power transformer coil? use an Ohm meter and check the resistance of the coils. No resistance is an open circuit. Also check for a cross circuit from one side of the transformer to the other.
Primary winding carry more current. We measure the current in one single wire, so no of turns are 1, in secondary the no of turns are higher. so, obviously it has higher voltage then this wire. so, finally as per the transformer rule the secondary carry lesser current than primary.

If rated voltage is applied to Transformer during S/C test, The secondary winding will burn out due ta heavy current flow through the winding. During S/C test the secondary winding is short circuited so the impedance between phase and neutral is very low(only winding resistance). But the voltage across the secondary winding is rated hence heavy current flows through the winding, as I=V/Z. it depends which rated voltage is applied. if you are talking about primary winding voltage, transformer should withstand the primary rated voltage it's been designed for (OR it has been poorly designed). Otherwise, if rated voltage is the insulation voltage between a winding and earth OR winding-to-winding, you just have to check if: 1 - it is higher than the maximum primary winding voltage the transformer can withstand (could be, could not be..). Then, you can guess if your transformer is likely to burn or not. 2 - your test setup (usually a HV generator connected between primary and secondary winding) can deliver the requested current for the setup. I guess this won't be the case, since HV testers are usually designed to generate high voltages, but very small output currents.

i have no idea but maybe this is a possibility voltage is inversely proportional to current the voltage in the primary coil is lower than in the secondary therefore the current in the primary coil is higher than in the secondary coil in order to reduce energy lost in the primary coil, the resistance is lowered by increasing the cross-section area of the coil as R is inversely proportion to area So maybe it is thicker to reduce energy lost in the form of heat, thus making the transformer more efficient
1500A. You probably have pri / secondary confused. primary is usually used to denote the higher voltage winding, which will have more turns than the secondary. The secondary will have lower voltage, less turns, but will carry more current.
Find out the volume of that object and then the mass of it and divide the mass by the volume to get the density.Comment:The answer given above is very wrong(in electricity).Answer:Bus bars carry high currents and thus a current transformer is used. It uses the bus bar as its primary winding and its wound section as its secondary winding. The magnetic flux of the bus bar due to its current is very small thus the current in the secondary windings will be small as well and safe to measure with a traditional Ammeter.NB: These types of work must only be carried out by a qualified electrician. Don't put your life at risk.
A step up transformer converts low voltage,high amperage current to a high voltage,low amperage current. It requires large diameter wire to carry the high amperage in the primary coil.
For carrying Short Circuit Test on Power Transformer Do the following: 1] Isolate the Power Transformer from service. 2] Remove HV/LV Jumps and Disconnect Neutral from Earth/Ground. 3] Short LV Phases by Cu/Al plate which could withstand short circuit current and connect these short circuited terminals to Neutral 4] Energise HV side by LV supply (440 3ph Supply) with OLTC tap position on Normal. 5] Measure Current in Neutral, LV line voltages, HV Volatage and HV Line Currents on various OLTC Tap position. Analysis: If Neutral current is near to zero transformer windings are OK If Neutral current is higher or equal to Line current between LV Phase one of the winding is Open.
