Hi There,
I am in Nasik and need to buy a step down converter. Can somebody give me a phone for a store in Pune or Bombay that I can call and order a step down converter?
Thanks

COuld you share any/all info you gathered? We are in the midst moving to Pune.
lpax;141519I want to buy a 230->110V converter in Pune. Do you guys know a good reliable place to do that? I live in Aundh but can travel to the city if necessary.

sanjeevkgarg;143353How much does a 2000W step up transformer cost approx. Deciding if I should buy in US or buy it in India. Need it to run my Vitamix Blender. Also just for comparison, how much a 200W will cost?
Were you able to use the vitamix successfully? I tried with a adpter that claimed to be 1600 watt. Vitamix started but I could feel that it was not getting sufficient power. So I turned it off.
I saw a huge sized transformer today that claimed upto 2000 watts but I wasn't sur if that will resolve the problem. I read somewhere that even though it is 2000 watts but Indian current comes at 50 hz so it is not able to provide sufficient torque to a 60 hz appliance and hence it seems it is not getting sufficient power.
If you found a transformer / adapter that was able to run the vitamix successfully please let me know.
Thanks,
Surbhi

Can step down transformers handle high voltage, voltage greater than 240V? What I have realized is that in India, there is a big problem of high voltage. I had multiple devices fail because of high voltage (upto 250V). Most of the step down transformers only handle up to 240V. Do they have enough coil to handle 250V?

I had
bad experience in getting my TV and Bose audio system getting fried up due to high voltage fluctuations when I connected the units directly to step down transformers, which directly connected to power outlet. Since I got a stabilizer hooked in between power outlet and step-down transformer, i have had no issues. There are different kinds of stabilizers at every possible range. You may want to explore that.
Investment on these step-down transformers and stabilizers itself took a big hit on finance and also on space at home. Sometimes, I wonder whether it was worth or not.

Here are two of my previous posts, they are lumped together here for you to give you an idea as to what the Electrical standards are. Please see if it makes any sense. If it does, then, you are a genius.
I will give an example to make it simple. If you are using a blender that uses 400 watts of electricity and of course uses a transformer for the current source, as we all do most of the time, load it up with Ginger, coriander leaves, dry garbanzos, chillies and coconut chunks and start the machine, we expect it to draw just 400 watts of electricity. But since the blade has to churn and encounters all of the ingredients at once when we start it, it will demand SIX times the current it normally uses just at the starting time. So, we will be loading the transformer excessively and it will draw a PEAK Load.
Once it runs for a few minutes and settles down, it will draw a normal running current. It might just be 180 watts or slightly more.
Now comes the crunch, if the local electrical Utility company supplies you its power at a POWER FACTOR of 0.3 PF, then you will be drawing 18 times the normal running current just at the START. It is only momentary. The Transformer might take it. We don't know for how many starts. It puts a strain on it. What it does is, it heats up the guts in the transformer, the insulation, when it heats up slowly becomes crisp, then flakes off and then falls off and leaves the wires BARE and one day it gets SHORTED and BLOWS off. " KAPUT". Some time it takes the appliance together with it.
Just like what the drunk said to the lamp post. "United we stand, Together we fall".

Most of us are not Engineers. If we are then, we would not buy an appliance that calls for a STEP DOWN Transformer. Because, if the appliance packs up, you will have to buy another one or end up with a useless transformer.
Now to the W5. Most of us take into account the voltage, the amperage, and the wattage. We should also take into consideration the ambient temperatures and the circulation of air around it for dissipation of heat. But we forget one other factor for which there are no meters on the system to check with. Here the blind faith takes over. In one place they say "Kadavule" and in another "Jumping Jesus". In the United States they say "Oy Vey" and I happened to see it on the Brooklyn Bridge too.
This Factor is called the Power Factor. It is at rate at which the Utility Company supplies the power to you. (Or supposed to) Generally we expect it to be ONE or Unity. But in actual fact, it could be as low as 0.3 and you can safely bet it is as close to it most of the time. What this does is, it makes you use THREE times the usage and the cost of power to you goes up three times as well. Well, if it stays there then we all will be happy.
But, it now calls for a transformer three times the size of what the wattage that one calculates or calls for. It does not stop there. There is another requirement that kicks in at the start of an equipment, it is called the "INRUSH" Current. That is the amount of AMPERAGE the machinery sucks up from the line at the time you press on the start button or when you put the switch ON. For motors and Rotating equipment it could be as high as SIX times the running amperage.
Now what does that do. It now wants you to buy a transformer Six times the previous calculation. It gets compounded now to 18 times the wattage. If you don't buy one that size, then it takes a toll on the transformer and also the appliance every time you put it on for usage. That is the safety factor you should look for initially for a COOL operation of the TOTAL PACKAGE. Do we ever consider this?? NO.!
So, as a thumb rule, if you buy one that is THREE times the total wattage of all of the appliances that you want to use on one Transformer, you can get away with all of these factors comfortably. Or Buy a small one for each of the appliance, a proposition which is a lot cheaper, than to buy a huge costly one.

The output of a step-down transformer is proportional to its input. High voltages are not a problem for step down transformer, but will be for the output, as in a 220-110v step-down the output is half of the input.
One way is to add a stabilizer in between the power and step-down, as its easier to get a 220v stabilizer (Rs. 1500) in India. Other option is a UPS (Rs. 2000) between the power and step-down. Provides 4-8 minutes extra power in addition to stabilizing, if you are equipped with a back-up generator.

I request more clarity on this.
My understanding is that the Utility generates power at PF nearly 1. Number of power stations have Capacitor banks to bring the PF to 1 when leaving the station. Depending on transmission and distribution lines as well as surrounding area (industrial or otherwise), the PF may not be that bad and would normally be above 0.8 (which is bad enough.) It is our loads that cause the PF to slide.
An incandescent bulb, toaster, kettle, room heater would normally be PF nearly 1 eqpmnt. Fans, tube lights and various modern eqpmt draw the PF down.
A number of utility companies recommend a capacitor bank in the consumer premises to reduce the current drawn.
Could you educate me on my understanding.
