@ulrikcaspersen9145 Год назад

Probably one of the best videos of this subject. I do believe, however, that you neglected to mention that sometimes transformers with the same number of turns on both the input and the output are used for certain applications. The purpose of that design is to be able to transfer power between two different circuits at the same voltage, but keeping them electrically isolated. If I'm not totally wrong, it is similar in function to a heat exchanger where energy, in the form of heat, is transferred between two isolated systems.

@chimrichalds5205 Год назад

Referred to as 'isolation transformers' and are used mainly to test/troubleshoot damaged and/or outdated/unsafe electronics. Largely as a safety precaution for Vacuum Tube electronics of the pre-60s/70s as they necessarily require high voltage supplies which could electrocute you if accidentally touched while open or if a fault shorted the hot side to the chassis. I forgot exactly but the transformer breaks one possible path for the current to travel through you if you came across the live while touching something grounded

@that1electrician 11 месяцев назад

Isolation transformers are used all the time for supplying non linear loads i.e. VFDs and other electronics that are prone to damage from voltage spikes. We had an overhead AC crane that kept tripping on overvoltage faults. We would simply bucket up to the crane bridge cabinet and reset the drive. This was going on for months and we were getting tired of it. We got ourselves a 75kva isolation transformer and installed it in between the main switchgear and the breaker panel that fed the crane. After wiring the xfmer after the switchgear and before the breaker, we never had an overvoltage problem again.

@charliethiede3992 2 года назад

This is very informative thank you. I am an automotive tech and in these gasoline engines you need to break the dc current somehow in the primary coil to collapse the magnetic field. Due to the principle of electromagnetic inductance this produces a surge in voltage in the secondary coil. Your explanation goes even further and makes me understand more deeply.

Model train sets, door chimes, radio with tubes like RCA Radiola 60. pole pigs or distribution xfrmrs on utility poles. Actaully there is a tansformer in your car, the ignition coil. It too has a primary coil powered by the 6 or 12 volt battery, The points worked by a cam would energize the primary, when the points opened high voltage jumped the spark plug and in old car radios with tubes, there was a vibrator that alernatively powered a split primary or a center tap and the vibrator powered one leg then the other and this made the hig voltage for the plates in the tubes.

At 11:50 minor correction. KVAR is stored energy due do reactive components (capacitors or inductors). It is charged and discharged throughout the system and it is stored energy. However the result is a reactive power creates higher current over your transmission line which result in greater losses. KVARs are sometimes desirable and are used for voltage control.

@rasmus1600 2 года назад

Aren't capacitators used to lower the VAR and increase the power factor due to a bad cos(phi) by the system only having spools? Then it makes the watt-less(reactive) power fluctuate from spool to capacitor without any energy consumption? Or have i completely messed something up in school?

@MojashYT Год назад

@@rasmus1600 Yes, but it depends on which side of unity you are looking. Capacitors can be used to reduce inductive VArs; the same way inductors/reactors can be used to reduce capacative VArs. We generally see commercial use requiring motors that all have inductive power factors, for this reason you have probably seen capacitors used to reduce VArs (inductive) by adding capacative VARs. The cos(phi) as you mentioned is a phase lag/lead description of the VArs; and can give a physical description of what the motor induction effect has on the voltage/current waveforms, and likewise how the capacitor introduction can remedy this. It also shows how Real Power (V*I) is lost as cos(phi) increases. Draw the current and voltage graphs at unity (they align); then draw a power wave (V*I). Repeat the same process with some amount of cos(phi) offset on either voltage or current waveforms. Redraw the Real Power (V*I) graph. You will see that with some amount of phase offset, the RMS real power decreases.

@brettski74 2 года назад

A few others have said it, but you have reactive power wrong. It's not wasted as heat. Anything generating heat is consuming real power. Reactive power is temporarily stored and returned to the circuit by reactive elements like capacitors and inductors or other devices that exhibit some amount of capacitance or inductance. Reactive power does increase current flow and thereby increases losses due to parasitic resistive effects, such as the resistance of your wires or the eddy current and hysteresis losses in your core, so generally speaking, poor power factor will likely reduce the efficiency of the overall system. In one of your graphics you also labelled power factor as "Efficiency" and you also appeared to have used efficiency and power factor interchangeably after your beer glass analogy. Efficiency and power factor are not the same. While a power factor closer to unity is probably going to be better for efficiency, they are different quantities. Also, I'm not sure if this was just part of your analogy, but it sounded like you said that electricity customers pay for apparent power. This isn't true anywhere where I've lived - at least not as a residential customer. Residential customers in at least Australia and Canada pay for real power, so you generally don't get penalized for poor power factor as a residential customer. I'm pretty sure it's the same in the US. This is why your bill says how may kWh you consumed and not how many kVAh you consumed. I'm not sure whether other jurisdictions penalize small consumers for small power factor or not. Large industrial and commercial users may have different contracts with their utilities that charge them more or less based on their power factor.

@seraglioborneo2803 Год назад

Well written post. But even domestic/ residential customers help keep the power factor close to 1. The fan manufacturers, where I live, put a capacitor (capacitive load) in the circuit to oppose the inductive load of the fan motor and bring the fan's PF closer to 1. I don't know whether this is mandated by law or done voluntarily by the fan mfr to "help out" :) I do know I only pay for reactive power at my residence (68 yo, male, retired), in South Asia. Also I have had fights with my wife and 2 grown up D (if these 2 are around at that time) when they want to run some appliance off the solar panels when the main supply is absent. Try explaining that though the mixie motor may be rated "only" as 750 w, using it makes lights go dim and affects the TV/ computer! I have come to a stage where I am informed about the need to run the mixie, I shut off my computer and other non essential loads and give the green signal. Even then it comes as a surprise how dim the only light on becomes as the mixie motor takes both resistive and inductive loads from the panels. I also want to praise the man who "invented" the concept of square root of (minus 1) as the ONLY way to deal with electrical circuits having inductive/ capacitive loads! Along with the wheel, 2 brilliant inventions.

@kvlpnd 2 года назад

At 11:50, I would like to suggest a correction. Reactive power is not wasted energy. It is actually wasted energy capacity (transformer in this case). Reactive power just comes back and forth from load and source. So, it is not wasted but only consumes conductor capacity which reduces conductor capacity available for active power.

@samfisher874 2 года назад

This is my understanding as well Keval Pandya. I used to work in our state's energy efficiency program and we specifically banned power factor correction devices because they don't save energy (but many mistakenly think they do). It's more about the capacity of the conductor not being used efficiently to deliver power if anything, but not energy efficiency.

@kvlpnd 2 года назад

@@samfisher874 As an discom engineer here in India, drawing reactive power is heavily discouraged by attracting penalty. Though I don't understand why power factor correcting device should be banned.

@samfisher874 2 года назад

@@kvlpnd You're correct, bad power factor is heavily discouraged here in the US in California too. Customers are encouraged to use power factor correction devices if power factor is bad, and if they don't correct for bad power factor there will be a penalty on the bill. But separate from that, is the electric utility's energy efficiency program which gives customers money to purchase efficient LED lighting, premium efficiency motors, etc. Since bad power factor isn't wasted energy, power factor correction devices are not eligible for that money. Occasionally, a misleading/misinformed salesmen will incorrectly claim that a power correction device will save a customer lots of money by reducing energy (kWh or Joules), so it's specifically banned from receiving energy efficiency program money in California. (Hope I explained that well, it's 2:30 am here...)

@4DRC_ Год назад

@@SystemHacker23 Honestly I find it best to avoid analogies and just present a practical example. Motors don't go from totally inactive to totally active - capable of delivering torque to the output shaft - the exact moment electricity is applied. You have to get the core going with some amount of current to magnetize it before it is capable of doing useful work. This is the parasitic inductance. And at the end of each half cycle, the field collapses and this current is returned to the grid. The transmission lines don't know what this current is for, they just see a higher current on them going back and forth, which leads to higher I^2*R losses. Which is why power companies hate poor power factor, and they encourage you to place power factor correction capacitors close to the motor. That way, the capacitor provides this current to build the magnetic field, as well as receive it again when the field collapses, and the power company only delivers the current going into real output power from the shaft. Consider the parasitic inductance as a shunt element in parallel with the resistive/real power drawn from the output shaft. As a shunt element, it reduces the impedance seen by the grid and causes an increase in apparent current draw, thus higher I^2*R losses on the transmission lines, which are in series (resistors) with this network. When the capacitor is placed also in parallel in the network, it will resonate with the parasitic inductance, and as parallel LC circuits present an open circuit at the terminals at resonance, the parallel LC tank circuit basically becomes an infinite impedance in parallel with the resistor representing shaft power = the circuit simply becomes the transmission lines in series with the real output power of the motor.

How the increasing in frequency helps to decreases the size of transformer🤔

@PlayboyHZ 2 года назад

Each AC cycle electric energy is converted to magnetic, and back again. The amount of magnetic energy that a transformer can 'store' is more or less linear in its mass. At a higher frequency, more of these cycles occur, hence the same transformer would transform more power, or the same power can be transferred by a smaller transformer. For further interest, study transformer equations and it Will be more clear.

In india they use 3 phase transformers and the secondary side of the stepped end down version has 3 phases and 1 neutral in total 4 outputs. Each phase ranges between 215 volts to 240 volts and neautral being zero. Each home will either have 1 phase n neutral or 3 phase and neutral. The primary side has 3 phases . Each phase has around 11kilo volts.

We have the same system here in The Netherlands, do you have any video suggestions where i can see how this type of transformer work?

@iessasr3657 2 года назад

There is a simple way to calculate current ,number of turns and the voltage according to the ratio: Vp/Vs=Np/Ns=Is/Ip=constant ratio Where: Vp is primary voltage Vs is secondary voltage Np is primary number of turns and so on....

It's been a long time since I learned about transformers (in much much greater detail) but I believe you got one thing very wrong! Reactive power is NOT wasted energy! It's more like an useless energy that oscialates back and forth. It's still unwanted from the efficiency perspective since it takes capacity and causing some increased heat losses due to apparent current being higher than true/usefull current. Power factor is also known as cos (phi), not to be confused with transformer (or whatever) efficency (n or eta)

PF and cosphi are two different things..

@lovrorb 2 года назад

@@snowywhite9663 Wrong, they're the same thing if we assume a perfect sinusoidal wave. In reality there is allways some harmonic distorsion quantified with THD

I work with them all the time on vintage arcade/pinball games. Lighting is usually either 6 or 12 v ac., and coils use 24 or 50 volts. Some motors and heavy duty coils run off the household current. They very rarely fail, though new folks sometimes think they do. Your video shows how simple they are with no 'moving' parts, though they can vibrate after they have seen many duty cycles.

Hi, Paul! I like your videos, they're maximally simple and thus understandable! Thank you for your content! Can you make a video with an explanation of the difference between a magnetic field and an electric field, along with explaining the difference between the inductors and capacitors? That would be great!
