Q:I noticed that I haven't seen a female transformers, which leads to two possibilities, they were gay or asexual.: I'm gonna be a nerd for a minute here (something I do too often). There were female transformers. I'm not sure why none were in the first two movies, but if you watch the Generation 1 series or Beast Wars (the two series I saw of Transformers when I was in Elementary School), then you will see female transformers. But it's never discussed, in any series I know of, how transformers were created. I guess children who like to play with action figures don't give a crap about that stuff. Nerd time over.

Q:Transformer how to do no load test: 3, through the no-load test can be found in the transformer the following defects: Poor insulation between silicon steel sheets. Between the core, between the pieces of local short circuit burn. Wear the core bolts or tie the strip, the pressure plate, the yoke and other insulation part of the damage, the formation of short circuit. Magnetic circuit in the silicon steel loose, dislocation, air gap is too large. Core multi-point grounding. The coil has turns, inter-layer short circuit or parallel branch turns ranging from ampere-turns and so on. Misuse of high consumption of low quality silicon steel sheet or design calculation is wrong.

Q:What is an isolated ring transformer?: Isolated ring-type transformer is mainly focused on its insulation performance, between the primary and secondary must have a double insulation, so that the isolation of its own high efficiency, effective protection of equipment safety.

Q:Hi, thanks for reading my question. I'm an electrician with some basic knowledge of electricity but this is puzzling me. In the USA, a single transformer on a pole means split phase. Three transformers on a pole means 3 phase. What does two transformers mean? Is it split phase with a high leg?Thanks: That is an excellent question. A single phase transformer is referred to as a split phase because it is center tapped. What that means is that the transformer as a whole is 240V with a wire tapping the coil in the center and grounded to create two separate 120V legs. The single phase transformer is essentially split into two pieces which is where the split phase terminology is derived. Three phase banks are three separate transformers working 120 degrees out of phase which is an ideal balanced setting for three phase commercial load. You can almost create true three phase using two transformers. The phase separation isn't ideal, but it does work when three phase service isn't available or a single phase service is needed in addition to a three phase service off the same bank of transformers. The term high leg is derived from the non-ideal phase orientation which creates a higher single phase voltage on one leg. BTW am I the only one tired of seeing one or two know it all people answer all the engineering questions even when they obviously haven't got a clue?

Q:I'm a beginner in electronics ,I have a big , old transformer (I think it is AC) , only supplies + current. (36 Volts)I also need - current to drive an amplifier.So i think it's an AC to DC converter i need. (It's just a guess , i don't really know.)How can i achieve this ?Note : If you need additional details , please include how i can get that detail , just in case i don't know.: You need to a have a rectifier to convert AC to DC, Before designing a Rectifier, You should make the specification of your input in terms of 1. Voltage 2.Maximum current requirement

Q:Electrical Machinery, Electric Machines, 3-phase transformers: Generally if you see three single phase transformers all mounted on one pole( not sure what a hydro pole is?), they are connected to supply three phase service to the customer. Not usually three single phase services, at least in the USA. The three single phase transformers may supply 208Y/120 volt 4 wire three phase, 120/240 volt 4 wire three phase (usually one of the transformers in this configuration is larger than the other two), 240 volt three wire delta or 480 volt delta, or a 480/277 volt 4 wire service., And on and on. This is determined by the voltage ratios of the transformers used and what the local utility supplies as a normal service voltage. Hope this helps, Newton1Law

Q:assuming a delta connected single phase transformers , why is the neutral side is connected to ground, my question is will the current be shunted to ground since it has a low resistance??? please explain: In electric distribution structures transformers are available countless sizes. Heavy ones are generally located on the floor with a concrete pad located under it to furnish help. those pad fastened transformers are risk-free against touch with the regularly occurring public generally with a fence. Pole fastened transformers are lighter and can be accurately located immediately on the skill pole. i don't comprehend of any floor fastened transformers different than for transformers located in vaults while the distribution strains are underground. yet those additionally desire some form of pad under them.

Q:I have a friend who lives in a place that she converted to a liveable space at a movie studio complex; however, the space is right above the transformer used by the studios for power. At night we can sometimes hear some buzzing sounds. How dangerous is this? We've heard things like it causes cancer in the long run, and that it is simply not safe. Does she have to worry about it? She's been there about two years.: Transformers can produce powerful electromagnetic fields, but there is no definitive answer on the safety of living next to transformers. Some people believe the electromagnetic fields cause health problems, and others do not. Bona fide research on health risks has produced sometimes contradictory results. One thing is for sure, high capacity transformers occasionally explode if they get overloaded, but these types of transformers are not allowed inside of buildings.

Q:440 volts should be as dangerous as 11,000 volts because a transformer does not dissipates power it just converts voltage into current, my question is if the power at the secondary region is the same why it is said that it is not as dangerous.: You are correct that a transformer does not, ideally, extract any energy from the system. However, it's not always so straightforward to get the energy from the secondary into, say, a person. If the wires from the 440V secondary touched my clothes, I'd probably be safe because the cloth will insulate me from voltages like that, and thus no current will go through me. But if the wires from the 11kV side touch my clothes, the cloth will break down electrically under that high potential, allowing the current to go through me and fry my entrails.

Q:Do not all change the pressure? What is the difference?: Transformer is the same frequency of a voltage into another level of voltage, such as the (frequency 50hz) 10kv into (power frequency 50hz) 400v. The inverter can convert DC into any frequency (there are many types of inverter, the output voltage frequency range is different) AC but the voltage level will not change.
