I'd like to point out that your question is asking for the secondary voltage, which is usually lower than the primary, where there are more windings on the secondary than primary - Thus your secondary is higher voltage than your primary. I would say the question should be worded differently so the primary has 500 windings, and the secondary has 100 windings.
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.
as secondary turns are less than primary turns so it is step-down transformer.
Single-phase electric power refers to the distribution of electric power using a system in which all the voltages of the supply vary in unison. Single-phase distribution is used when loads are mostly lighting and heating, with few large electric motors.Do you know that there is a proposed 800-mile high-voltage direct current transmission line from Oklahoma to Tennessee?Read more about it by clicking on the link.AnswerA single-phase transformer is a simple transformer which will either step up, or step down, a single-phase voltage. A single-phase supply is a two-conductor alternating-current system, comprising a line conductor and a neutral conductor.As most high-voltage electrical distribution systems are three-phase systems, comprising three line conductors, a single phase distribution transformer's primary (high voltage) winding is connected between any two of the three high-voltage line conductors. As far as the secondary (low voltage) winding is concerned:in Europe, one end of the winding is earthed and provides the neutral terminal , while the opposite end provides the line terminal (L)in North America, the winding is centre tapped and grounded, providing the neutral terminal, while opposite ends of the winding provide the line terminals L1 and L2
A step-up transformer increases (or "steps up") the voltage of an alternating electrical current. For example, a step-up transformer could be used to increase 120V AC to 277V AC to provide power to 277V electrical equipment in a building that does not already have a 277V electrical system.Other examples where a step-up transformer might be used include these:Using 240V AC equipment with a 120V AC mains supply.Generating high voltage for use with tubes, such as a CRT.Generating high voltage for use in electric energy distribution.
Carbohydrates are used when the body is at rest it also depends on fat. In high intensity exercise it also uses coarbohydrates.
Yes, it starts with the producers - plants, then to the primary consumers - herbivores and omnivores, then to the carnivores then to the decomposers, which breaks down dead bodies into nutrients essential for plant growth.
Increased biodiversity is thought to increase the robustness of an ecosystem. In a more biodiverse ecosystems, the removal of one animal or plant has a less detrimental effect on the survival and success rates of the animals and plants connected to it in the food web.
The ratio of windings between a primary and secondary in a transformer govern the output voltage. Multiple taps are connections to various points in the coil effectively changing the winding ratios to get multiple voltages from the same transformer. Taps can be on the primary, secondary or both to provide a more versatile transformer.
600 volts is five times the 120 volt primary, so the secondary winding must have 750 turns, which is five times as many turns as the 150 turns of the primary winding.
in isolation transformer earthing is not provide on secondary side but in ordinary transformer neutral of secondary side is earthedAnswerAn isolation transformer is a 1:1 ratio transformer; its function is to electrically isolate the secondary side from the primary side without changing the voltage. An example of an isolation transformer is the one used in a shaver socket.A distribution transformer is a step-down transformer, used within the electricity network's distribution system. An example of distribution transformer is a pole-mounted transformer, supplying low voltage to residences.(Of course, all mutual transformers provide electrical isolation between primary and secondary.)
Primary current is a flow to be measured that cannot be safely passed through the measuring device. A current transformer is used to provide a lower level, secondary current that can be passed safely through the measuring device. Primary current is measured as a secondary current, multiplied by the turns ratio in the current transformer.
A 'current transformer' (CT) is classified as an instrument transformer, which means it is used to provide a small secondary current that is in proportion to its large primary current, for purposes of metering or protection. At the same time, it electrically-isolates the secondary (metering) circuits from the primary circuits (which are often high-voltage circuits) for the purpose of safety.
A step-down transformer's primary is high voltage and secondary is low voltage, based on voltage configuration or load we select which winding we do fast.In air-cooled Transformers output voltage is high and load current is low. So in air cooled low voltage winding in side and high voltage winding in out side of the coil . So we can reduce high voltage short problems and we can easily provide coil insulation . reduce short problem. It is cooled in oil.In step-down transformers we can do high voltage inside of the coil and low voltage and high current of the coil is outside. Because we can better coled in outer side . and reduced to temp problems.AnswerThe terms 'primary' and 'secondary' do not relate to a transformer's voltages, but to how its windings are connected. The primary winding is connected to the supply and the secondary winding is connected to the load. So, for a step-up transformer, the secondary winding is the higher-voltage winding while, for a step-down transformer, the secondary winding is the lower-voltage winding. Your question, therefore, should ask whether the higher- or the lower-voltage winding is the 'inside' winding (i.e. the winding closest to the core), and the answer is that it is the lower-voltage windings are innermost and the higher-voltage windings that are outermost.
Disconnecting the secondary of a current transformer results in an attempt to generate large voltages across the secondary. This can cause arcing, damage to equipment, or hazardous conditions. This is because a current transformer is a 1 to many turns ratio device. The primary is one turn, while the secondary is hundreds or thousands of turns. It reduces current but, like any step up transformer (which is what it actually is), it can produce high voltage when not loaded. The intent is to provide a low impedance load across the secondary, so that secondary current is proportional to primary current, as opposed to the inverse condition for voltage, which is what will happen if it is unloaded.
An autotransformer is no different than a regular transformer. It has "effectively" two windings, a primary and a secondary. Its just that one end of the primary is connected to one end of the secondary. It can also be said that it has only one winding, and that there is a tap someplace in that winding, but the end result is the same. Depending on how it is connected, it can step up or step down the voltage. Some autotransformers have multiple taps. Some, called variacs, have a sliding contact that allows relatively fine control of the output. The up side of an autotransformer is that it can be easier to build. The downside is that it does not provide electrical isolation between primary and secondary, nor can it filter harmonics as well as a dual winding transformer.
I don't know what kind of transformer you are talking about, but most utility distribution transformers are star connected on the primary side.AnswerIt might be different in some other countries, but in the UK, three-phase distribution transformers are always connected in delta on their primary (high voltage) side, and in star (wye) on the secondary (low voltage) side. The primary line voltage is 11 kV, while the secondary line/phase voltages are 400 V and 230 V.In the United States and Canada, the primary winding is also connected in delta -however, the secondary side is also connected in delta, with one phase centre- tapped to provide the split-phase 240/120 V arrangement.The reason for using a delta connection is because three-phase high-voltage lines are supplied as three line conductors -there is no provision for a neutral- so there is no practical advantage in having a star-connected primary.
The burden on a CT is the sum total impedance connected to the secondary - including the CT secondary winding coil resistance, lead resistance, and any loads attached (relays, meters, etc.).If this is for power calculations and CT saturation in three phase systems, remember you must multiply the lead resistance by two to get the total path resistance.Another AnswerWe use the word, 'burden', to describe the load supplied by the instrument transformer's secondary. This is normally a measuring instrument or protection relay. We use the word 'burden' to distinguish it from the 'load' supplied by the circuit to which the primary winding is connected.
Transformer polarity is the direction the secondary goes relative to the primary, or relative to another secondary. Usually, polarity does not matter, for example in the case where the secondary is connected to a rectifier / filter / regulator. Sometimes, it does matter, particularly if there are two secondaries used to provide DC isolation between a preamp and a final amplifier in push-pull configuration. It can also matter if the overall circuit is involved in a feedback loop and phase inversion is a factor.AnswerWhen applied to transformers, the term 'polarity' describes the direction in which the secondary voltage is acting relative to the direction of the primary voltage. Polarity is determined by the directions in which the primary and secondary windings are wound relative to each other.Polarity is described as being either 'additive' or 'subtractive', and can be determined by of connecting one pair of primary and secondary terminals together. If the voltage measured between the other adjacent primary and secondary terminals is greater than the primary voltage, then the transformer has 'additive' polarity; if the voltage is less than the primary voltage, then the transformer has 'subtractive' polarity.Knowing the polarity of individual transformers is important when two single-phase transformers are connected in parallel with each other because, if polarity is ignored, then an incorrect connection might result, causing a large circulating current through the two secondary windings.
No, a transformer changes the ac to a voltage that the user requires. After that a rectifier can be connected to it to provide dc.
