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.
Primary and secondary key in DBMS?
key is nothing but a attribute and attribute is the aspect of a member in an entity entity is represented by set of attributes. primary key is the one which is selected by the database designer to identify a entity in a entity set super key is one or more attributes which is used to identify the entity in an entity set uniquely candidate key minimal number of super keys... in some context super key and secondary key are equal. foreign key is the relational constraint between tables or entities A secondary key is made on a field that you would like to be indexed for faster searches!

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 do you identify p side and n side of a diode using a multi meter?
To identify the p-side and n-side of a diode using a multimeter, set the multimeter to the diode mode. Connect the positive lead of the multimeter to the suspected p-side of the diode and the negative lead to the suspected n-side. If the diode is connected in forward bias (p to positive, n to negative), the multimeter should show a low forward voltage drop. Conversely, if it is connected in reverse bias, the multimeter should display an open circuit.

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 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.
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 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 can I use a multimeter to test guitar wiring effectively?
To test guitar wiring effectively using a multimeter, set the multimeter to the resistance or continuity setting. Then, touch the multimeter probes to different points in the wiring to check for proper connections and continuity. If there is a break in the wiring, the multimeter will show a high resistance or no continuity. This can help identify and fix any issues with the guitar wiring.
Why is the transformer turns ratio test needed?
Turns ratio test is very important in order to find out that the transformer has the right ratio corresponding on its rated voltage in primary and secondary. For example, three phase transformer is subjected to turns ratio test when each phase has equal turns ratio then the transformer is balance.The test is performed to ensure that overheating or overcurrent conditions have not shorted turns in the transformer windings, which would distort the desired output or input voltage. This test is particularly important for instrument transformers, i.e. CTs and PTs which are connected to protective relays. These relays are extremely sensitive, and operate on very small fluctuations in secondary voltage or current. Shorted turns in these transformers can lead to big problems if they cause the relay to operate abnormally, or not at all.
