Q:S11-1250kVA transformer oil capacity how much: The total amount of oil in the transformer: the amount of oil supplied by the transformer body transport + (the amount of oil required to be added to the main body) + (the amount of oil added to the oil conservator) + (transformer accessories - such as the amount of oil required for the radiator )Wait. The amount of oil added in parentheses is the transformer factory, and the oil drum is installed and delivered to the customer. So customers receive the transformer, the transformer should be the total amount of oil is acceptable enough

Q:advantages of power transformers: Another advantage can be, depending on the application, isolation between primary and secondary circuits.

Q:Can the transformer be replaced with a component?: If you say the transformer is a small power frequency transformer, then you can use switching power supply instead. If the substation with high-power transformers, there is no thing to replace.

Q:Hello everyoneI have a 110V hardware plugged in at home (we use 220V) by way of a step down transformer and I was wondering if transformers 'use' more power than usual. I don't want a nasty electircal bill.Because even when the hardware is 'off', the transformer itself is still on. It still hums. I am wondering if the transformer is constantly pulling power out of the wall socket 24/7 if I leave it on.Any help will be greatly appreciated. Thanks all.: Mike, here is an easy approximation with no tech talk you can perform. Leave the power on to the transformer but remove the load and let temp stabilize. Feel how hot or better yet put a thermometer on the transformer. This heat is a direct result of transformer losses while idle. Next remove power to the transformer and devise a metal box to put a lamp in to heat the transformer overnight. Try to capture all of the lamp heat into the transformer to heat the core. Try this using various lamp wattages. When the temperature rise from the lamp equals the temperature rise from running the transformer idle the lamp wattage will be a close estimate of the power wasted by the transformer at idle. A wattmeter will also tell you this but they can be expensive. A good meter and an oscilloscope will be necessary otherwise but that is another story. Heat is always wasted energy the more produced the more it costs you to run. Regarding if you should let it run the answer is sure why not. You probably already have transformers running in your house all of the time. Door bell, Furnace, hot water tank, may be a few.

Q:Transformers have any way of cooling: Selection of strong air-cooled cooling mode, when the pump and fan lose power supply, the transformer can not run for a long time. Even if no load can not run for a long time. Therefore, two separate power supplies should be selected for use by the cooler. ????When the oil-water cooling method is selected, it can not be operated when the pump cooling water loses power. The power supply should select two independent power supplies.

Q:How do step up transformers obey the law of conservation of energy?: An ideal transformer neither generates nor consumes energy, so the power entering it will equal the power leaving it. Power can be computed by multiplying the RMS voltage by the RMS current. So, if an ideal transformer has an input voltage of (say) 100 V and an output voltage of 200 V, the current coming out will be exactly half the current going in. A real transformer is not ideal but dissipates power owing to the finite resistance of its windings and other effects, so if a real transformer steps up voltage from 100 V to 200 V, its output current will be less than half its input current.

Q:Can anyone explain what each wire does in this spicific microwave transformer: transformers is a movie, silly. your microwave is not an autobot, dont worry

Q:I need a specific transformer to make 5V go up to 170V. It can be a little high and I can just use a potentiometer to lower it if needed. Where can I find such a specific transformer?: Since okorder

Q:High-rise residential basement transformer noise is too large, how to solve, whether the need to shift, there is no other way to solve! Thank you as much as possible! If you have to do this project also please educated us!: You can consider doing transformer oil, and add noise equipment.

Q:Want to use in the air compressor, I do not know it?: Transformer oil can not be lubricating oil, because the main role of transformer oil insulation is not lubrication. The main role of transformer oil: (1) insulation: transformer oil has much higher than the air insulation strength. Insulation material immersed in oil, not only can improve the insulation strength, but also from the erosion of moisture. (2) heat dissipation: transformer oil specific heat, often used as coolant. Transformers run the heat generated close to the core and the winding of the oil heat up and down, through the oil up and down convection, heat dissipated through the radiator to ensure the normal operation of the transformer. (3) arc suppression effect: In the oil circuit breaker and transformer on-load regulator switch, the contact will produce an arc switch. As the transformer oil thermal conductivity is good, and in the arc under the action of high temperature can touch a lot of gas, resulting in greater pressure, thereby enhancing the dielectric arc performance, so that the arc quickly extinguished.
