How to make a transformer? What is the principle under it?


Do you mean an electrical transformer? You are far better off to buy one unless it is a special project. Constructing an efficient transformer is fiddly in the extreme.

The principle is that an alternating current (AC) voltage applied to a conductor will generate a fluctuating magnetic field around that conductor. The opposite also applies: a conductor in such a magnetic field will experience an AC current generated in it.

A transformer usually has 2 such conductors coiled around a common core, which intensifies and spreads the field. The voltage on the output side is controlled by the ratio of the 2 coiled conductors, or windings. So a transformer with 2000 windings on one side and 100 on the other has a ratio of 20:1. If a voltage of 240 VAC is applied to the first winding, a voltage of 12 VAC will appear on the other.

For calculation purposes the power is the same on both sides, so that lowering the AC voltage through a transformer implies raising the current at the same time, which can be handy. Therefore a transformer will often be rated by wattage, and input or output voltage. Note that a pure transformer will not work with or produce DC voltages, extra circuitry is required.

Generator


Your question doesn't make sense as it is written, but if the real question is what size generator do you need to start the air conditioner I might offer the following....

Look on the air conditioner product label and you will find information concerning the supply voltage and current. This is a 2 ton unit and it probably requires 220VAC power. Also on the label will be a value for the maximum OPD (over current protection device). This indicates the maximum fuse or circuit breaker that can be installed in the power feeder line for the air conditioner. You will need a generator that is capable of supplying this amount of current during the start up of the air conditioner. The value is usually about 2-1/2 times the normal operating current that the generator will need to supply continuously. This is because the air conditioner is full of motors that draw a lot of current when starting up. If the generator can't supply sufficient start up current, the motors will not start and the AC will not operate. As a result, the generator size is usually relatively large in comparison to the actual size required to keep the AC running after start up. This is also why AC units are not typically powered from generator power. Good Luck!

The generator kicked the breaker of and was smoking and smelled like electrical


What type of load (electrical) was hooked up to this generation?? If the surge voltage and current was exceeded above the generator maximum for any length of time. There problems, it could be the regulator, insulation burnt off the windings.


I am taking a guess here. Now, 7100 Watts is it typical surge wattage. This mean that the generator will deliver 7100 Watt (voltage times current) this is know as the power factor. The actual operating load would be 6800 Watts and I would even operator the generator at its peak wattage. Something in the neighborhood of 10--15% less the peak wattage. Therefore a good positive theatrical Wattage would be 5800 to 6350 operating wattage. Then this generator would run all day.



Just remember Ohm's Law. Current plays a big factor in loading of a generator while the operation voltage is at 120 AC Volts. Example: electric motor; Now electric motor when starting will pull three time its operation current. Operating current for a 1/2 HP AC motor is 6 amperes but start this electric motor will require 18 amperes. This is one reason why they starting capacitors on smaller electric motors. Larger three phase electric motor can literal stop a generator cold...in its tracks. It put such a large demand on the generator it stops the engine powering the generator. I have seen crankshaft break because the generator could handle the heavy current load.



Remember, any time you are running a small gas powered generator. All ways figure what the load and surge current load will be before hooking up any generator. Normally this is figured in VA (volt/amps). Wish you lock. GB...stewbison

We have a Valsi 5500 watt generator that isn't putting enough voltage out to run everything in out small travel trailer. It runs the lights but doesnt push out enough voltage to carry the A/C, microwave,...


How long have you had this generator?
Has the generator worked on all of these loads before?
Model 5500 is a 5500 Watt generator which could easily be 5500 watts (Peak) and not continuous.

Your AC is an inductive load.
Your lights are resistive loads

An inductive load can cause issues when starting due to an increased current demand at start up that some generators cringe under. Do the lights flicker or are they stable? I'd say your diodes on your stator are working if you have light stability but you haven't provided nearly enough information for a detailed solution.

I'm sure you have enough voltage but you aren't getting enough current to run specific loads. How many watts is your AC? How many watts for your microwave? Both of these units demand a great deal of energy to run and when you place too much demand on your generator, it will choke it out and eventually, will cause damage to the generator. You may consider getting a beefier generator with a greater amount of wattage output.


Seeing these specs online and noting what you are trying to run, you have an undersized generator and need to get one that can produce a greater amount of running wattage (as well as peak wattage).

New batteries and alt. still no charge.


Generator with Integral Rear Mount Voltage Regulator, Internal Fan Type With the key in the RUN position, voltage is applied through the charge indicator lamp I circuit to the voltage regulator. This turns the voltage regulator on, allowing current to flow from the battery sense A circuit to the generator field coil. When the engine (6007) is started, the generator (GEN) (10346) begins to generate alternating (AC) current which is converted to direct (DC) current by the rectifier internal to the generator. This current is then supplied to the vehicle's electrical system through the battery positive voltage (B+) terminal located on the rear of the generator. Once the generator begins generating current, a voltage signal is taken from the stator and fed back to the voltage regulator S circuit, turning off the charge indicator/lamp. With the system functioning normally, the generator output current is determined by the voltage at the A circuit. This voltage is compared to a set voltage internal to the voltage regulator, and the voltage regulator controls the generator field current to maintain proper generator output. The set voltage will vary with temperature and is typically higher in the winter than in the summer, allowing for better battery recharge. With the system functioning normally, the generator output current is determined by the voltage of the A circuit (battery sense voltage). The A circuit voltage is compared to a set voltage internal to the voltage regulator, which controls the generator field current to maintain proper output. The set voltage will vary with temperature and is typically higher in the winter than in the summer, allowing for better battery recharge in the winter and reducing the chance of overcharging the battery in the summer. A fuse link is included in the charging system wiring on all vehicles. The fuse link is used to prevent damage to the wiring harness and generator if the wiring harness should become grounded, or if a booster battery with the wrong polarity is connected to the charging system.

The Mitsubishi 215-ampere generator is an internally regulated, brushless unit that is self-current limiting and temperature compensating. The regulator is integral with the generator and the fan is external.

VISUAL INSPECTION CHART Mechanical Electrical
  • Before attempting to test a battery, it is important to give it a thorough examination to determine if it has been damaged.
  • Batteries are tested to determine the state of charge and ability to crank an engine. The result of these tests is to show that the battery is either good, needs recharging, or must be replaced.
  • Preliminary checks to the charging system should be made regardless of the fault condition. These checks include:
    • Check the fuses/fuse links to the generator to ensure that they are not burned or damaged. This condition, resulting in an open circuit or high resistance, can cause erratic or intermittent charging system concerns.
    • Check battery posts and cable terminals for clean and tight connections. Clean the posts and the cables to ensure good electrical contact.
    • Check for secure connections at the generator output, voltage regulator and engine ground. Also check the connection at the power distribution point.
    • Check the generator drive belt to ensure proper tension and no slip between the generator pulley and the drive belt. Refer to Section 03-05 in the Powertrain, Drivetrain Manual.
    • Check battery for full charge.
  • Before performing charging system tests on the vehicle, note conditions such as: slow cranking, discharged battery, charge indicator lamp stays on with engine running, charge indicator lamp does not illuminate with ignition switch in RUN and engine not running, etc. This information will aid in isolating the part of the system causing the symptom.
  • When a relatively new battery is discharged, test for current drain. The following are some of the most common current drain concerns:
    • Glove compartment lamp stays on with the door closed.
    • Engine compartment lamp stays on constantly.
    • License plate lamp or interior lamp stays on constantly.
    • Other electronic component concerns.

Do not field out the field wire.
Is the alternator ight coming on?
If you rev engine, does charging system start working?
There is a resister wire that provides voltage to the field circuit. If the resister is bad, you will only get voltage to the field through the dash alt. light bulb when you push enough voltage through it.

This system uses in conjunction with the transformers a rectifier which converts the High AC current voltage (220V-AC) to a Low AC current voltage (12V-AC) and then the rectifier converts that energy into the D/C current (12V DC). The two diffrent 12V power sources are controlled, operated by a "electric" relay, via a roadside or electric selector switch. DS_TK TECH
