What is a static transformer?

It's a transformer that operates with AC current in and out. It's an ordinary transformer, with the term "static" used to differentiate it from rotating transformers, such as motor-generator sets.


What is the term for the transformer winding to which the load is connected?

The load is connected to the transformer's secondarywinding, while the primary winding is connected to the supply. The terms, 'primary' and 'secondary', do NOT relate to voltage levels.


What is the impedance of a transformer?

Impedance (Z) voltage is the amount of voltage applied to the primary side to produce full load current in the secondary side. It is usually listed on the transformer nameplate, expressed as a percent, and measured by conducting a short circuit test.


Why a transformer called machine?

The term "machine" in the context of a transformer may be a bit misleading, as a transformer itself is not a machine in the traditional sense. Here’s why a transformer might be referred to as a machine: 1. Electrical Device: A transformer is a type of electrical device that performs specific functions similar to machines. It changes the voltage and current levels in an electrical circuit, which is a form of electrical work. 2. Mechanical Analogy: In engineering terminology, "machine" can refer to any device or apparatus that performs work or a function. Transformers fit this broad definition because they perform the work of converting electrical energy from one voltage level to another. 3. Complexity and Operation: Although not a machine with moving parts, transformers are complex devices with multiple components (such as windings and cores) that work together to perform their function. This complexity might lead to the term "machine" being used informally. 4. Industrial Usage: In industrial and technical contexts, the term “machine” can sometimes be used to describe any equipment or apparatus involved in electrical or mechanical processes, including transformers. In summary, while a transformer does not fit the traditional definition of a machine with moving parts, it is often referred to as a machine in broader or industrial contexts due to its role and complexity in electrical systems.


How do rectifier circuits stabilize the output voltage when the input voltage is subject to fluctuations?

Rectifiers don't "stabilize the output voltage" of rectifier circuits when input voltage fluctuates. The rectifiers just rectify the input, and the output will fluctuate as the input does. Another form of "conditioning" of the rectified output is needed to address the issue of fluctuations. And we use the term regulation to talk about the effect of "stabilizing" an output voltage. Through regulation, the output will be resistant to changes in voltage when changes in the input voltage occur.

What is an isolation transformer?

AnswerAn isolation transformer does not have a direct electrical path from the power input side to the power output side. The term is also used to define how much electrical isolation exists between the input and output windings. For example when using line-voltage input transformers to power low voltage device handled by humans, a high degree of isolation is required for safety.Isolated transformers often use separate bobbins for the primary and secondary coil windings, but usually the windings are just wound on top of each other with insulation in between.There is usually an electrostatic shield between windings which is tied to transformer case.Non-Isolated transformers are becoming rare. A common example is the "Variac" which is a non-isolated variable transformer. Usually the term "auto-transformer" is used to describe non-isolated transformers. They are rarely found in consumer products.Although any transformer with a separate primary and secondary winding is an isolation transformer to some extent, The term is usually used to denote a special-purpose transformer built just for that use. It is tested and rated to withstand a very high voltage difference, called the withstand voltage, so that even if thousands of volts are applied to the primary, it will not leak through to the protected side. These transformers are used in the medical industry, to protect patients hooked up to monitoring instruments that are powered by utility mains, as well as other uses.An 'isolation transformer' is a transformer specifically used to electrically-isolate the secondary circuit from the primary circuit. Of course, ALL mutual transformers do this, but an isolation transformer normally has a 1:1 ratio, which means its secondary voltage is the same as its primary voltage. In other words, its purpose is NOT to change the supply voltage, but to isolate the user from the supply circuit.Isolation transformers isolate the secondary circuit from the earthed (grounded) primary circuit. As there is no earth return from the secondary circuit back to the primary supply, isolation transformer eliminate the risk of shock between the secondary circuit and earth.An example of an isolation transformer is a bathroom shaver socket. The output is completely isolated from the earthed supply, so users cannot receive a shock between the outlet and earth.

What is VA burden in electrical engineering?

The term 'burden' is used to describe the secondary load applied to an instrument transformer; the reason for this is so that it is not confused with the 'load' supplied by the high-voltage circuit to which the transformer's primary is connected. A burden is either a measuring instruments (ammeter,voltmeter, wattmeter, etc.) or protective relay, depending on the function of the instrument transformer. 'V.A' is the symbol for 'volt ampere', which defines the 'power' rating of the instrument transformer.


How do you reduce Transformer 6VA to 3VA?

In 2 words, you cannot! It is like asking how can I make a 60W light bulb into a 30W light bulb. If you are wanting to know this because a specification dictates that you need a 3VA transformer then anything larger is OK. However, you must pay attention to the voltages on the transformer. Firstly, assuming that this transformer is to operate on the mains supply, it should have the correct primary voltage for the mains supply in your area. In most, though not all of Europe, it is standardised at 230V 50Hz. The secondary (usually the output) should have the desired voltage output. This, for example, might be 6V A.C. If it is the only output then, if it is a 6VA transformer, it will be able to supply 1A maximum current. If it is a 3VA transformer, supplying 6V, it will be able to supply a current of 0.5A maximum. The term VA is for Volt-Amps. It refers to the power that would be developed in a resistive load. Hence the secondary voltage (V) multiplied by the maximum current rating (A) gives VA. Thus, if you have a transformer rated at 12VA and the secondary voltage is 5V then the maximum current the transformer can supply is VA/V=12/5=2.40AAnother AnswerThe volt ampere rating of a transformer simply indicates the maximum load it can supply without overheating. The same transformer can supply ANY load below that value. So there's absolutely no problem operating a 6 V.A transformer at 3 V.A.
