Brief Introduction
The"JDCF"series voltage transformers are inducitive type,single phase,oil filled,outdoor type.It accords to the GB 1207-1997<voltage transformer>,IEC 186 and IEC60044,This type of voltage transformer is of cascade full seal construction,The product consists of winding assembly,porcelain housing,transformer oil,base and stainless steel Bellow.
The primary winding of 110KV or 132KV voltage transformer is divided into two parts,wound separately around the upper and lower core,Wound around the lower core,three secondary windings are respectively measuring winding,protective winding and residual voltage winding.
The primary winding of 220KV or 230KV voltage transformer is divided into four parts,wound separately around two cores.Wound around the lower core,three secondary windings are respectively measuring winding.protective winding and residual voltage winding.
The active part is located to the base by suporting frame made of high quality insulation materials and is put into porcelain housing with degassed and de-watered transformer oil after vacuum treatment,All outlet wires of secondary winding and the terminal "N" of primary wnding are connected to the epoxy resin board which is in the waterproof and dust-proof terminal box of the base.There is a valve for oil-filling or oil-exhausting on the base.

- Q: Go transformers
- Between those two , Transformers.
- Q: I was planing on buying transformers but my friend told me about skyrim and it looks pretty good, which one is better and funner?
- Transformers: okorder
- Q: What are the ways of protecting the transformer?
- Transformer protection is commonly used to protect the internal fault of the main protection of gas and differential. Backup protection is quick and overcurrent. There are semi-insulating structure of the neutral point over-voltage protection (arrester), oil temperature alarm.
- Q: How can you tell. Is it because (3) wires come off of a single phase transformer? And (4) off of a three phase transformer? Thanks!
- Looking at a transformer intended for mounting on a utility pole, you would see insulating bushings protruding from the metal case. The longer bushing or bushings are the high voltage bushings. The smaller bushings are the low voltage bushings. A single phase transformer would have only one or possibly two of the long high voltage bushings ( typically coming out of the top of the transformer on newer designs intended for mounting on poles typically by a utility ). A three phase transformer would have at least three or possibly four of the long high voltage bushings. All power transformers should also have a Nameplate permanently attached to the case. Primary bushings are typically identified on the nameplate with a H designation such as H1, H2 etc. Low voltage bushing are identified by an x designation such as x1, x2 etc. Make certain that the transformer is NOT energized before attempting to look at a nameplate or come near a transformer. Multiple single phase transformers may be connected into what is called a transformer bank to produce three phase power. At least two single phase transformers are necessary to make a three phase bank of transformers.
- Q: Are there any transformers action figures that arent for little kids like from the movie and are collectables? LINKS?
- I used to play international of Warcraft. I remember being point 60 (the max on the time), and looking after agency in Ironforge. It replaced into annoyingly effortless to have low point newbs whisper me with, Gold Plzzz!!! and i desire 2! and am i able to have some gold? It replaced into rather stressful.
- Q: I would like to use this circuit to power arrays of high power LED'sI understand the properties required to power LED'sI have beginners knowledge in electric circuits and have done some research on this circuit. I have come across several posts stating it is dangerous to connect this circuit straight to mains power. I don't understand is what makes it is so dangerous?AndIf possible, how can it be made safe without using a transformer.
- The neutral leg of the AC (assume the bottom on the diagram) is grounded to earth ground at the house service entrance and also at the center tap of the power pole transformer (in the US). If your project box was metal, and you had the 0 volt output attached to the metal case and happened to touch earth ground through you. You would get shocked since during the negative half cycle, positive voltage would go through ground, then you, the metal box, through D4, back to the AC hot (on the negative half cycle). Ouch! Always use an isolation transformer or any transformer where the secondary is not in any way tied to the primary. That way you can ground either dc lead from the rectifier to ground and not have to worry about electrocution.
- Q: By applying ohms law in the secondary circuit, IV(stepped up)/R , a stepped up voltage would result in an increase of current, i am aware that the step up transformer steps down current, but it is the secondary circuit that determines the current draws (ohm's law), and the primary current is multiples of itSo ?!!!!
- E IR P (watts) I^2 R or E^2 / R there have to be TWO transformers. gererator medium V, I first step, up, Hi V low I, Transmission loss low; low I^2 x R line Second step, down V, Low (220 or 110) V; High I, 50 to 100 amp for house hold. high I on motors and lights, high heat loss. high I needed for motor torque. edison had DC, did not understand AC math DC required huge I in transmission lines and limited line lenght to a few miles at most. due to I^2 R loss. Without complex number math for AC Electrical calculations we would not have the same technology that we do have, or radio. Math is the queen of science, Nerds rule
- Q: Hey!I Love Shia Labeouf I Was Wondering If Transformers Was A Good Movie I Haven't Ever Got A Chance 2 Watch It. Is It Worth Watching? These Are Some Of The Films I Like.Pirates Of The Caribbeanthe Dark KnightSpider man 3 Home Alones Mean GirlsThnxxP.S. I Heard Theres Going 2 Be A Transformers 2! D
- Transformer is honestly the sickest movie of all time. Are you kidding me. I watched it at least 7 times, and I had to buy the movie when it first came out. Only movie I have ever bought, and I didn't even like transformers that much growing up.
- Q: Can someone tell me what the tiny transformers are. I remember that they are somehow activated using some green energy device. I'm not even sure if that is it
- It depends what you mean, do you mean from the original 80's show The Transformers or the later show Transformers: Energon, which was part of the Unicron trilogy. The only one I remember small transformers 'activating' in is the second one. If you meant the original, I'd assume you were talking about the cassettes, which Soundwave and Blaster had. They weren't activated with any sort of green device but they were smaller Cybertronians that transformed into tapes and were stored in their 'tape-master's chest. This would include Rumble, Ravage, Frenzy, Ratbat, Lazerbeak and several other with make small appearances (Decepticons). There was Ramhorn, Rewind, Eject and Steeljaw along with a few others. (Autobots) Picture: tfwiki /mediawiki/images2/0/07 Official name: Cassette Next is the Unicron trilogy. In this the main focus of the show was that apart from the Autobots and Decepticons there was another faction, the 'Mini-cons', which were small and powerless on their own, but they could be used as power-ups by the larger 'bots, so they were sent into deep space for their own protection. These ones were 'activated' as such in that they formed a sword or shield or similar that could only be used by a larger bot other than acting independently as a small Cybertronian. They shared a lot of the same names as the 1980's continuity characters, but these are the ones I was talking about, they're about the size of a human.

- Q: What is a transformer?
- Transformer role is generally there are two, one is the role of step-down, the other is the impedance matching effect.
