Fake charger caused that next time get original one

It's not the charger Dude, he must have used one or three of them before.
It's the stabilizer that diverted the reactive power generated by the alternator back to the coils, forcing a double excitation in the rotor.

Let me explain something here
We use stabilizers for Nepa because most of there lights are either below or above 220mw and most electronics we have works well when on 220mw
Our generators are set already on 220mw, so no need to stabilise the current because its already stabilized by the gen

220mw ?

Proudlyngwa:

Stabilisers regulate voltage not current, and they can be used on generators without issue, problem should be with the governor of the generator going bad.
Look at it this way.
Compressor of fridge needs times 3 running current to pick.
While doing so , voltage drops as power is constant.
Stabilizer boosts the voltage while more current is being drawn.
Engine tries to adjust itself
Governor overviews while generator AVR fails
Excess current supplied to other appliances.
Some times this things are self repairing.

If AVR fails in an alternator set up, voltage = 0 and not increased

most people has been condemning the use of stabilizers with generator.mind you a stabilizer as the name implies, stabilizes voltage to a certain degree for effective usage of appliances...while you have no control over PHCN light to regulates it when its high or low or even fluctuates, a generator has control to set its voltage to a particular level which can be checked through a volt meter attached to it..which means you can set your generator to a desired voltage and still use your stabilizer..your stabilizer does not affect anything..its only very useful for phcn light which can fluctuate, without you having power to regulate it to desired voltage...as a mechanical engineering student, what I suspect could cause that sudden rise in your generator is from the carburretor..the carburretor malfunctioned by supplying much fuel mixture to the combustion chamber without it being controlled by the owner, hence there was an increase in the speed or timing of combustion which transmit fast power to the piston, which in turn drives the crankshaft the alternator is connected to...when the alternator moves faster, it produces more voltage because of the speed the coils moves around the magnetic field in the alternator chamber....if you want to have a full voltage from your generator, you drive a screw from the generator, this screw being driven causes the carburretor to be open for more fuel and air mixture which is supplied to the combustion chamber, which in turn adds to the piston drives..the piston drives the crank shaft that now drives the alternator...if your generator is high, it will consume fuel, unlike when its normal or runs very low..also it affects the supply of current respectively, except the capacitor or diode is bad..I hope this is comprehensible

If you will allow me to enlighten you, then tag along, if no, please just ignore.

There is nothing like 220mw on a small/domestic generator, it is 220/230V for Nigeria.
Secondly, you can use freezer with a stabilizer, technically termed Voltage Regulator.

The problem OP had was probably with the phone chargers which I suspect are faulty thereby causing a short circuit fault.
Those chargers must have been very hot beforehand which led to the terminals melting and there was a leakage from live to neutral.

I have been using my generator to power my freezer vid the stabilizer (voltage regulator) and there has never been a single issue like this.

Check ur carburator and there something call governor raising attached to carburator that might be malfunctioning.

ibuildstuff:

The fact that u said stabilizer step up or step down electrical voltage, and that they don't consume any electricity shows u have absolutely no idea what u are talking about.

Stabilizer give out a steady voltage output with the aid of voltage regulator. Stabilizer does not step up or step down voltage, it's transformer that does that.

Secondly, all electrical appliance consume electricity, all must pose a form of resistance no Matter how small the resistance is.

There's not electrical appliance that doesn't consume electricity.

are you aware that the job of stepping up or stepping down your voltage by your stabilizer is done by a TRANSFORMER inside the stabilizer? every stabilizer has a TRANSFORMER inside it. there are also a set of relays that do the job of voltage switching. it's the relays that make the clicking sound you hear when using your stabilizer. again, it's the size of the transformer that determines the load the stabilizer can carry. now, the transformer itself is simply a coil of wires around a primary and a secondary core with input and output points...nothing more. strictly speaking, a stabilizer doesn't actually consume electricity as such....it's the appliances connected to it that do.

adedayourt:


The reason you experienced such is because of the stabilizer you plugged with it.

Here is why.

Most Stabilizers only increase current rather than stabilizing it in actual sense. Observed you wont experience that when you plug with NEPA source.

So when you used the stab with gen(assuming a 2.5kva now), the gen will try to boost the gen beyond its normal output capacity thereby overworking the gen and when the output is increased few gadget gets damaged.

In my case, no gadget got damaged but the gen itself after a long time of overworking

O boy you don mistype o , and you typed at length sef. A stabilizer increases current? For where? What electrical principle do you have to back up this claim? Stabilizers don't consume electricity, they only step up on step down to the rated voltage. What we should be looking at is the AVR of the generator. If the load on the generator is too much what would happen is that the circuit breaker would turn off or the generator will shut itself down as a safety approach. Since there was no damage to the generator windings nor the refrigerator, our best bet should be on the AVR.

The number of likes this your suggestion has gathered showed the level of ignoramus we have in this country. You might not have been once in science class let alone being an electrical engineer.
There is no problem using stabilizer with generator. As the name implies, Stabilizers stabilize the voltage output. Stabilizers are designed to come with AVR(Automatic Voltage Regulator). It regulates the amount of voltage it gives out no matter the input and provided that the input voltage is within the capacity limit of the stabilizer.
The problem here is the generator.
The engine has what we call governor. It regulates the speed of the generator. When it is not set properly or has problem it could rise with increase in applied load.
To guide against this the electrical side being the alternator also comes with AVR. This is to regulate voltage output in case the governor has problem.
To trouble shoot on this, there is need for a competent person to look at the governor and AVR to detect the exact problem.
Let us say what we know.

Thank you my brother. I almost questioned my knowledge on electricity by the number of likes on that post

frowland:

Your AVR is bad.

Very underated comment. You were the first to point to something accurate.

seniorkachion:


I started using my 1kva stabilizer with my 2kva Thermocool 2500 generator. After servicing it for the first time in 7 years the current indicator needle always hovered between 120 to 150 votes. My fridge when connected directly to the gen as usual would start and cool for about 5 Minutes and stops cooling, though it would be humming.
I had no option than to connect it with the small supermaster stabilizer. It's been working for me, two days now. Only piston with it's rings and alternator brush was changed. What could be wrong with the gen. Plus it's tough to pull the starter.

I wanted to scream when you said you serviced for the 1st time after 7yrs. Then I realized you probably meant an en engine overhaul. Usually a general rule of thumb to apply is this, anytime you perform an engine overhaul you must reduce the load to 30-40% for the 1st 2 running as well as limiting the duration its on. After the first 2 you can continue as usual.
Does your fridge work well when used with the mains?

Been doing same for the past 8 years and never had any issue. I use a 4kva Gen though!�

joey150:


Give a reason? A valid electrical reason why you cannot use your stabilizer and generator?

I've used mine for five years now, not one problem.
You can argue that it is redundant, but I'll like to know why you think it spoils anything.

you are trying to make sense because I know where you are going to, 220V not 220MW. The above that says he made a mistake plugging Stabilizer to a Genset does not have knowledge of electricity. GENSET gives voltage according to it's rating, STABILIZER is is a dual purpose device unlike power surge, STABILIZER steps up voltage if the voltage is low & step down voltage if high (not very high). the working principle of the GENSET makes the speed easier to be control through the GOVERNOR by controlling and adjusting the load. finally, the STABILIZER iS faulty, it steps up the voltage instead of stabilizing it to a required voltage

Raycelove:
We on our generator to freeze the items kept in the freezer, we connected stabilizer with the freezer, this was our first time of connecting stab with freezer.

So the hell mistake I made was removing my phone from the original charger and charging it with an infinix fast charger, after plugging the phone , the generator level went high and the fast charger got burnt the original charger, my sister laptop charger got burnt , bulbs got burnt.

We were lucky not to on our televisions and other valuables. We off the gen and on it again without the freezer on and the sound and motion went back to normal.

So what caused the change in level of the generator and what led to the damages of laptop charger, bulbs and chargers??

Bross, the fault is not from your GENSET since it's Governor is ok but the STABILIZER. Stabilizer is a dual purpose device that designed to STEP UP voltage & STEP DOWN. Stabilizers are normally preset from 0-300V which makes it a bit reliable but to a limit, it is been regulated to give out voltage beyond 300V so my brother that Stabilizer is faulty, it suppose not to step up the voltage to beyond 300 but it does. your problem came from the STABILIZER not GENSET

[quote authore post=97365153]
The keyword in my statement is 'properly'!
U also need to find out the functions of the two components!
Avr is made of voltage regulators whose primary function is to maintain a certain amount of voltage in order to avoid a spike in voltage and also current....capacitors functions as a 'electrical charge storage' component!
Between the two,which would you likely want to use as your output to your appliance?[/qu

You are right about avr but capacitor also does. The work of avr too

lovecares34:
You are not supposed to connect your freezer to a stabilizer while your Gen is on. That was the mistake u made. Next time, plug the freezer directly and not through a stabilizer.

You absolutely got it. No sane person plugs the Stabilizer to a gen set. Not that the chargers are bad but the stabilizer distorted the free flow of electrical current.

oga next time dont plug stabilizer to generator biko. sorry about your lose

What type of gen r u using?

So na the stabilizer affect the bulb too...
You are wrong sir

Not in dispute with you, Use a stab with ur gen and be happy

Have you used a gen with your generator for a sustained period bfore?

The guy just typed crap from the pit of hell & you find it educative and concise?
What did you learn from this? Please explain in your own words.

Just123:




Very educative and concise, this is the kind of content I signed up for.
Thank you.

Ecne:

If AVR fails in an alternator set up, voltage = 0 and not increased

No it does not equal zero it only makes voltage fluctuate based on nature of load, carburettor efficiency and engine stability.

That is why their is a potentiometer for stability control

adedayourt:

I do that most times.

An AVR in generator already regulate the light so adding a stabilizer will be an overkill.

Does your fridge work well when used with the mains?

I meant it was the first time the gen developed a fault after 7 years of regular use.
Yes, the fridge normally works with the mains. Using it with a stabilizer for the past few days is a departure from the norm. I still plan to try using it with the mains after one week.
One thing I have noticed is that while the voltage indicator on the gen hovers between 120 to 150 volts, the input into the stabilizer is full current at 250v.

Aside mikano generator, which gen below this range could make your freezer freeze your food items?
