Q:I have an old xray machine with a large step down transformer.Its not shorted but the paper insulation looks to dry. Is there a special oil for this? Thanks.: The manufacture of the transformer would have provided environmental protection. There are many ways to provide protection but most involve large pressure cookers that are designed to apply high pressure to the transformer will drying. Various waxes and epoxies are used and the pressure makes certain the sealer is driven into the transformers windings, then allowed to set. As far as I know, except for certain types of large transformers where the entire transformer is installed in a bath, oil is not used.

Q:1000KVA transformer power loss is how much: It depends on its kind of transformer oil-immersed transformer or dry, 1000KVA dry-type transformer no-load loss of about 1.5% to fill the load loss of 3%, oil-immersed transformer no-load loss of about 3% to fill the load loss of 5% The above is just for reference, because each manufacturer has a difference.

Q:I have a transformer 12v and 12v need to reduce these further to be able to grow or shrink the rotational speed electromotor.Which device or component would be used to reduce the speed of electromotor?I making a mini escalators: A transformer has AC output, so first get DC, which needs a rectifier and capacitor. Following this is a voltage regulator using an LM317 (adjustable 3 terminal regulator). This can delivers ~1 amp. You should know what maximum current your motor draws under load. The first link is an example for 1.25V-15 V with an 18V transformer. Use a 12V transformer, and a 1000 ohm potentiometer as a variable resistor instead of 2000 ohms (R2). This will give voltages from 1.25V to 7.0V DC. Use the formula to calculate other resistors for a different voltage. Get the LM317 in a TO220 package, and you will need a heat sink, at least as big as in the picture. You can probably find a kit of parts for this in an electronics shop.

Q:I have 14 gauge wire and some 28 gauge wire. Do both lengths of wire have to be insulated? Is it as easy as winding the 14gauge wire top to bottom and then do the 28 gauge wire top to bottom also? I'm guessing this is a step up transformer because the battery is going through the 14 gauge wire and then the lightbulb is hooked to the 28 gauge wire?Does the direction on winding matter at all? Say, CW for the 14g and then CW with the 28 gauge?: ferrite rods are not customarily used for transformers. at RF they are sometimes used as a core for a loop antenna. your application sounds like an ignition coil as you need an interrupter on the DC input (like points on a car ignition). the primary wire (14 gauge) would just be a few turns and not likely to run the full length top to bottom, the secondary (28 gauge) would be a lot of turns like 10 or 20 times as many. direction of winding would not matter in this application as capacitive coupling between the windings should be insignificant. all wire has to be insulated as a shorted turn spoils the transformer effect. wire used for transformers is customarily insulated with lacquer as plastic adds too much bulk to make tight windings. if you already have bare wire, then you made have some success by dipping the wire in lacquer paint first. it sounds like you are duplicating a project you have seen elsewhere. without knowing the source, it is hard for us to guess what the circuit parameters need to be for the transformer. but as i pointed out initially, i am skeptical that you will get this to function in the manner you are expecting. AC power transformers of the kind that use these wire gauges always use a torroidal core ferrite, never a rod. static DC cannot be transformed at all.

Q:BQ: Which director do you like more: Michael Bay or Steven Spielberg?BQ2: Are you excited about Transformers 3 or worried that it can be not good?thanks :)))) lt;3: Steven Spielberg of course, you can't use him in the same breath as Michael Bay (well ok you can because hes one of the executive producers of the Transformers movies. But in general Spielberg has given us masterpieces like Jaws, Close Encounters of the Third Kind, E.T, Raiders of the Lost Ark and serious and moving films like Schindler's List, Saving Private Ryan, Amistad, Munich that have won him academy awards. Although he has gone downhill fast with Indiana Jones and the Kingdom of the Crystal Skull. Michael Bay is good for throwaway, explosion fest movies. Spielberg was one of the pioneers of the Blockbuster movie along with George Lucas, so Spielberg still rules, without Spielberg there would be no Michael Bay. And I would have to go with Indiana Jones (except for Kingdom of the Crystal Skull) but I'm not one of those who bashes Transformers either they deliver exactly what they are meant to and the CGI effects and sound effects are totally mind blowing, I wouldn't say I'm excited about Transformers 3, its the third not the first but it should be enjoyable none the less although I find Shia La Beouf annoying and what no Megan Fox!!

Q:I have a packaged heat pump w/ Emergency Heat that is not working and does not come on at all. No lights or anything even when I switch it to emergency heat. Someone said that it could be my low voltage transformer. What is that and how do I check it?: A low voltage transformer on an a/c and heat system is a device that lowers the line voltage down to a safe 24 volts to run in control wiring to your thermostat to control your system. If your thermostat has a removable cover where you can see the wires underneath it is easy to see if you have no low voltage as long as you have a volt meter that can measure 24 volts ac. Make sure the thermostat is off and measure the voltage from R to any other terminal and you should read 24 volts nominal (more likely somewhere around 27) If you don't read 24 volts minimum you have a problem in the low voltage circuit. Most heat pumps will have some kind of low voltage protection such as a fuse or small circuit breaker in the unit so it doesn't necessarily mean the transformer is blown. The more important thing is to find the reason that caused it and that requires thorough understanding of the system. It's really best to have a technician diagnose this kind of problem.

Q:The book said the main transformer power failure operation should first stop the load side after the power side, is to prevent the transformer in the case of multi-power reverse charging. What is the transformer anti-charging here? What's wrong?: Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). In electrical equipment and wireless circuits, commonly used as lifting voltage, matching impedance, safety isolation and so on. ?????? When the transformer is shipped, it is determined whether it is used as a step-up transformer or a step-down transformer, and its relay protection setting requirements are specified. If the transformer is a step-up transformer, it is determined that the low-voltage side is zero-up. Such as from the high side of the anti-charge, then low side of the open circuit, due to the relationship between the high voltage side of the capacitor current will cause low voltage side due to electrostatic induction and over-voltage, easy to breakdown low-voltage winding. If you determine the normal high-voltage side of the transformer, such as from the low side of the anti-charge, then the high side of the open side, but the excitation current is large (up to 6 to 8 times the rated current). It produces the electric power, easy to make the mechanical strength of the transformer is a serious threat, at the same time, relay protection device may also hide the inrush current and malfunction.

Q:Hi,Should i wait for the Asus Transformer Pad Infinity, or should i buy the New iPad ?Thanks,Patrick: Transformer Pad Infinity. The new iPAD is exactally like the iPAD 2. Dont let them fool you with the X after the A5 on the processor. Technically its the same. The Transformer Pad Infinity is the first Quadcore tablet in the market with the targea 3 and quite frankly thats reason enough to bypass the New iPAD anyday.

Q:What is the temperature of the dry-type transformer?: It depends on the insulation of the transformer is how much. Generally the highest temperature has 105/120/130/155 degrees and so on. Normal use, more than 80 degrees on the need to use the cooling measures. Another dry-type transformers do not install the temperature sensor, then it is not alarm, only installed the temperature sensor will!

Q:How does the core material affect a transformer? Such as if you use steel vs. air. Or wood vs. magnet.: A transformer is a gadget that converts an alternating (A/C) modern of a definite voltage to an alternating modern of diverse voltage, without substitute of frequency, via electromagnetic induction. A 'step up' transformer gets a low voltage and converts right into a miles better voltage, and a 'step down' transformer does in basic terms the opposite.
