Usualy the largest current is at the lowest voltage side ; so the largest conductor section determine the lowest voltage side ; if the transformer is a set up one , the primary will be the lowest voltage winding ; in the other hand , it 'll be the highest voltage winding

How you can find out transformer primary and secondary turn?
The primarys are marked with the letter H and the secondary terminals are marked with the letter X. The rest depends on how many phases, single transformer, bank transformes, secondary outputs desired, delta or wye or both, etc..... A: most of the time there are not marked with anything. for a power transformer the primary will offer a resistance of 15 ohms the secondary can be more or less depends on applications
Why mentions the nameplat of transformer in vector group?
A transformer's 'nameplate' lists all the data necessary to identify the rating, connections, etc., of a transformer. Part of this data is the 'vector group' information which applies to three-phase transformers, and which, in simple terms, tells us whether or not the transformer can be connected in parallel with another.
Why need transformer oil test?
A DGA (Disolved gas analysis) is needed to identify certain types of damage a transformer may experience. After a severe fault, a DGA test is often performed to determine whether there might be damage to the transformer, or if it is safe to re-energize.
What is phase and neutral?
You really should be asking what is 'line' and neutral.In Europe, the secondary winding of a distribution transformer has a pair of terminals. One is connected to earth and, therefore, has a potential of approximately 0 V with respect to earth. This terminal is termed the neutral, and the conductor connected to this terminal is called the neutral conductor. The other terminal is termed the line, and the conductor connected to this terminal is called the line (not 'phase'!) conductor. A distribution transformer's line conductor has a nominal potential of 230 V with respect to the neutral.In North America, distribution transformers' secondary windings have three terminals. The centre terminal is grounded, and provides the neutral. Each of the outer terminals acts as a line terminal. The nominal potential difference between each of these two line terminals is 240 V, while the nominal potential between either line terminal and the neutral terminal is 120 V.
How do you identify the leads of a diode?
There are two wires on a diode: Anode (positive in) and Cathode (negative out). A diode may have a grey band at the cathode end, and black at the anode end. Diodes come in many sizes and capacities, some with clear markings, some without, so there are times when a multimeter has to be used. Set the multimeter to the diode setting (looks like an horizontal arrow fired from a bow, with three lines meeting at the arrow-head's tip). Touch one wire with the red + probe, and the other wire with the black - probe. If there is no reaction, electricity is not flowing. Reverse the probes and you should get a reaction showing that electricity has been detected. So the red probe marks the anode wire and the black probe marks the cathode wire. If there is no reaction, whichever probes are tried, then the diode is dead.
How can you identify which one is step up or step down transformer?
A transformer has two windings, termed the 'primary winding' and the 'secondary winding'. The primary winding is the winding connected to the supply, while the secondary winding is connected to the load. The secondary voltage of a 'step up' transformer is higher than the primary voltage; the secondary voltage of a 'step down' transformer is lower than the primary voltage. The simplest way to determine whether a transformer is a step up or step down, is to measure the primary and secondary voltages. If you are simply looking at a transformer, then the transformer's insulated bushings will give you a clue -the higher voltage bushings are much bigger than the lower voltage bushings. If you have access to the inside of the transformer, then the higher voltage windings are thinner and have a greater number of turns than the lower-voltage winding.

How can you identify the primary secondary of a transformer on a schematic if it is not indicated?
Without knowing the type of transformer (audio/power, step-up, step-down, etc.) it's difficult to offer any advice.
How could you identify the less coil number side of a transformer?
By measuring its resistance with an accurate multimeter provided the coil is not blown. If less resistance compared to that of the other coil would decide that it is less number turn.
How to differentiate 110v or 220 transformers?
The way to identify any transformer is to look at the the transformers nameplate. The primary side will be designated H1 to H4. This is the primary side and the voltage will be stated as to the voltage to connect to. The secondary side will be designated X1 to X4. This is the secondary side and the voltage will be stated as to the voltage it will be transformer to.

Identify the difference between primary sector and secondary?
Identify the difference between primary sector and secondary sector
How do you measure the resistance of a transformer?
Use a multimeter on the ohms scale. put the two leads on each of the primary terminals and read the resistance. Then put the leads on the secondary side of the transformer and read the resistance.
How do you identify step up or step down transformer from phasor diagram?
Number of turnsAnswerI assume that you have a phasor diagram of a transformer, and wish to identify the primary phasors and the secondary phasors?For a three-phase transformer, this is fairly straightforward, provided the usual procedure for drawing a phasor diagram has been followed. Whenever you start to draw anysort of phasor diagram, you usually start by selecting a phasor of reference and draw that in the horizontal positive direction. For a three-phase transformer, the phasor of reference is usually the primary phase voltage A (or however else it is identified: R, red, or whatever). The remainder of the primary phase voltages are then drawn, enabling the primary line voltages to be constructed (which, in the case of a primary delta are the same as the primary phase voltages!). So if you can identify the phasor of reference, then you have identified the primary-winding phasor diagram. As the primary and secondary voltages are not usually drawn to scale, relative to each other, you can't assume a turns ratio from the phasor diagram. The labelling might also help, as high-voltage phase and line voltages are identified by upper-case letters, while low-voltage phase and line voltages are identified using lower-case letters -but, remember, these identify high- and low-voltages, not which is primary and which is secondary (primary winding is connected to supply/secondary winding is connected to load).For single-phase transformer, the phasor of reference is the flux set up in the magnetic circuit, and voltages/current phasors are drawn relative to this. In this case, the primary line and induced voltages are usually identified as V1 and E1, and the secondary induced voltage as E2 (sometimes, the Es and Vs are interchanged). Again, the lengths of the primary and secondary voltages are not necessarily to scale relative to each other.
How do you identify primary and secondary winding without using an ohmmeter?
use the charlie crabtree, simple really. attach the charlie crabtree to the charlie crabtree then simple turn the crabtree to the ohmeter and viola you have charlie crabtreeAnswerIf you are able to see the conductors, then the higher-voltage windings will be thinner than the lower-voltage windings.The terms, 'primary' and 'secondary' have nothing whatsoever to do with the voltage-ratings of the windings. The primary winding is the winding connected to the supply, and the secondary winding is the winding connected to the load.
Why magnetic current test in transformers?
To identify transformer winding shortage. If there is shortage between winding turns magnetic current test is the best to identify. Shaukt from Abudhabi.UAE
