Q:Are Current and Potential transformers used for Step purposes?
The usual application of CTs and VTs is to provide isolation between the power system and instrumentation and/or protection equipment. And in this instance, the transformation is usually to reduce the magnitude of the voltage or current that is being measured. There occasionally are instances in which it is necessary to increase the magnitude of voltage or current. In most instances these situations involve relatively minor adjustments in the magnitude of voltage or current and take place in the CT or VT secondary. The transformers that are used to make these adjustments are typically called 'auxiliary' CTs or VTs. There are a few very specialized situations in which CTs or VTs are used to couple a signal into the power system itself. One example of this is where a high-frequency signal is superimposed onto the power system to establish a control communications channel. So-called 'power line carrier' signals are usually in the kHz range, and are typically coupled into the system via VTs - most often, capacitive VTs rather than inductive VTs.
Q:How do you choose the public transformer capacity?
800X8 = 6400KW 6400KWX0.5 (use factor) = 3200KW + 50KW mall = 32500KW (full load operation) Choose three sets of 1000KVA transformer ,, 3000 (KVA) X0.9 (functional factors) = 2700KW · · · · · · · · · · · · · · · · · · · · · · · · · 315KVA transformer for 670 is too small ,,, 670X8 = 5360KW, 5360X0.5 = 2680KW 2680KW / 0.9 = 2977KVA Choose three sets of 1000 phase change
Q:1:1 60Hz transformer used at 400Hz (Sine wave)What would be the secondary voltage?
this is yet in a diverse way. enable,Epvoltage around the popular winding; Es voltage around the secondary winding;Np # of turns interior the popular winding;Ns # of turns interior the secondary winding. Then, Ep (Es(Np))/N/s; (25(20))/one hundred500/one hundred 5V Step up transformer, or T turns ratio. T Ns / Np, one hundred/20 5v, Step up transformer. to your f.y.I in case you opt to parent a step down transformer,then, use the formula Es (Ep(Ns))/Np, or TNp/Ns desire this facilitates, persist with the electrical powered industry there's an incredible destiny and a few actual sturdy money to be made in it.
Q:Is the LTC transformer a regulated voltage transformer?
If equipped with a load regulator is called on-load tap-changer If equipped with no load regulator is called no-load voltage regulator
Q:Average transformer voltage ? rated power rating?
A transformer rating is specified as a number of volt-amps (VA) where A is the RMS current. In cases where there are rectifiers, the RMS current may be far greater than the average current. This means that the power that can be delivered will be far less than the VA rating.
Q:why doesn't the emf induced in the primary of a transformer does not cancel out with the supply voltage?
Leaving aside the double negative, the problem is your use of cancel - what do you expect - that it will go back to the generator and kill it? The transformer produces an output voltage which tries to do work against a resistance or inductance - the work it does produces a back EMF which the supply voltage works against so the generator has to do work. If there were no EMF in the primary, it would behave like a short circuit and blow the circuit - which is does in a small scale in the starting surge that you have to allow for when turning on equipment.
Q:Transformer size problem (kVA)?
buildings come in all sizes. Some use a lot of power, perhaps because of lots of machinery. Others use a much smaller amount. So you need to calculate or estimate the amount of power the building will be using. If you know the square foot total and use of the building (industrial, office, etc) there are probably tables that will give you a guess. One 240/120 panel for the entire building? That implies a very small building, as must buildings distribute 3 phase 208 volts, and have numerous subpanels. .
Q:Question on transformers?
Since there is no evidence to indicate any inefficiency of this transformer, you have to assume that it is 100% efficient, with input power equaling output power. Input power Vin * Iin Output power Vout*Iout Equate: Vin*Iin Vout*Iout Solve for Iin, our unknown: Iin Iout * Vout/Vin Data: Vout 110 V Vin 230 V Iout 0.15 A Result: Iin 0.072 As for the ratio of loops, the number of turns in each coil is proportional to the voltage across each coil. Thus, the turns ratio equals the voltage ratio of 110/230 0.478. That is to say, there are 2.1 turns in the primary coil for every individual turn there is in the secondary coil. The primary coil is the coil plugged in to the line voltage of 230 V. The secondary coil is the coil in to which the load plugs in, at load voltage of 110 V.
Q:Electrical machine Question.(Transformer)?
there are many criterion it is application dependant or power it is the load that causes a temperature rise that if loaded beyond it will cause failure of course it depends on the insulation material so a smaller transformer could have a much higher rating because it can stand more heat small electronic stuff will generally be when the transformer can no longer sustain the output voltage Anita
Q:Step-Up Transformer ?
voltage is inversely proportional to current, if the voltage increases then the current decreases . as long as the power remains the same. P I x V if you increase the voltage then the current should decrease proportionaly, that is how they can distribute high voltage over long distances using such small conductors . the current is very low
