1. Product Description:
The grounding transformer is usedin the three phase power system with neutral insulation, to provide artificial neutral point.
This neutral point can be directly grounded. It can also begrounded by reactor or arc suppression coil. With a secondary winding,
the grounding transformer can not only provide a neutral point for system but also provide power supply to other parts of system.
2. Product Characteristic:
Special environment should be informed such as altitude, chemicaldeposition, dirt, corrosive media, etc., for dry-type transformers insulation shouldbe provided.
l Mean annual temperature is +20℃and below +20℃(if it’s water-cooling product, the highest daily average temperature of cooling-water is +25℃)
l Altitude is not more than 1000m.
l Installation site should be without seriousvibration, bumps and chemical corrosion,

4. Reference Picture:
- Q: I have a 120v-36v transformer hooked up to a bridge rectifier composed of 4x IN4004 diodes, 2 filter capacitors and a 100k resistor paralleling them as a bleeder resistor. The rectifier puts out the full 50v DC I expect it to, but at the same time the transformer faintly vibrates (you can only really tell if you touch it), and over time it gets quite hot. Why is this? I have checked over my connections quite a few times and I am 99.9% sure its all connected properly.
- The transformer may be vibrating because the winding inside have loosened up and vibrating due to the varying magnetic field. But it is quite possible it may have a shorted winding this will definitely make it heat up and vibrate. Disconnect the filter capacitors and plug it back in if the transformer stops vibrating and/ or the transformer doesn't overheat you have a leaky filter capacitor.
- Q: For most consumer electronics, there'll be a transformer within the adaptor that converts AC to DC. For the basic of the transformer, I'll just assume it's just a primary coil running the secondary coil.So, the primary coil keeps on running at full power, as long as electricity is needed for the appliances. Does this mean that even on standby mode, the adaptor still takes in full power from the power socket?
- primary coil keeps on running at full power incorrect. wrong. The secondary has a load, and that load draws current, which may be anywhere from zero up to the maximum load rating of the transformer, say 10 amps. Depending on the turns ratio (say it is 10:1), that amount of current is supplied by the primary, multiplied by or divided by the turns ratio. In our example, this would be 1/10 th the secondary. So if the secondary drew 10 amps, the primary would draw 1 amp from the wall socket. If the secondary drew 1 amp, the primary would draw 0.1 amp. And 0 amps would cause the primary to draw 0 amps from the wall socket (for an ideal transformer. Real world, there is a small current being drawn, how small depends on how good a transfomer it is) edit, for your additional details. I determined that it keeps on running at full blast based on the idea that it's a separate circuit. wrong Since it is always creating magnetic field (which it must, since it's a coil), and creating even when no ones taps on it, it must run at full blast at all times. wrong, with no load, the magnetic field is much weaker. Unless there's a way the primary circuit automatically knows nobody is tapping on it, it must be constantly making magnetic field at full blast. wrong.
- Q: 150KVA transformer can withstand much power, how to calculate
- 150KVA is the capacity of the transformer, it can output the maximum power is 150KW. KVA = KW capacity number is the number of power without calculation
- Q: I haven't seen Dark of the Moon, but I recently got OBSESSED with Transformers. Please don't spoil anything, but I'm curious, how do they incorporate the new chick, Rosie, Huntington-Whitely, in the movie? Do they ever explain where Micheala went(Btw- I KNOW what happened to Megan in real life.that's not what im asking lol) So yeah, thanks!Bq: SAY OPTIMUS PRIME IF YOUR A GIRL TRANSFORMER FAN:)Bq: Do MOST girls like Transformers, or is it mostly guys who like it?
- They say that she left Sam BQ: OPTIMUS PRIME!!!!
- Q: Can dry transformers and distribution cabinets be placed in the same room?
- Dry transformers and power distribution cabinets can be placed in the same room. Oil-immersed insulation with insulating oil, dry type with resin insulation, dry-type safety is better than oil-immersed transformers. In the event of a fire or explosion, oil-immersed insulating oil may increase the risk of accidents, so need to be set separately, and the transformer base should have oil leakage design. And dry type change will not have such a danger, it can and power distribution cabinet set in a room, while dry-type transformers and distribution cabinets in the same room easy to overlap, busbar and cable consumption on the reduction, operation and maintenance More convenient, articulated ground and check the power outage when the glance.
- Q: I have an RCA 46 inch projection Tv model p46924 that doesn't turn on. Someone said I probably need a new transformer. What is it? What does it do? Where is it located?
- A transformer is part of the power supply. Takes AC from the wall and with other circuitry transforms it to DC power for the TV components. Just call a repairman. Don't attempt to fix it on your own.
- 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: What is the temperature of the dry-type transformer?
- Insulation heat-resistant grade for the F-class epoxy resin casting transformer alarm temperature factory setting is generally 130 degrees.
- Q: I purchased a doorbell in Europe, it has a transformer that goes from 220V to 14.8V, will the transformer work on 110, or do I have to replace the transformer?
- It shall not work on 110V. But you can feed the 240V find inside the power panel to this transformer to make it work. USA power system has both 120V and 240V existed in the power breaker box.
- Q: actually I've many questions :) I've opened many mobile chargers and I didn't found the usual (bulky) transformer . I found only a small transformer and I think it called smps transformer.1- I can't understand how bulky transformers can be replaced by small ones! what is the idea ?2- are smps transformers connected directly to 220 volt like the bulky transformers ? if no, what is the design of the circuit that makes small transformers are able to be connected to 220 volt ?3- do smps transformers make a voltage drop like the bulky transformers ? or they have another job ?4- some smps transformers have 4 pins and the other have 5 or 6 pins, I know it should have 2 pins for input and 2 pins for output, why some of therm have more than 4 pins ?Thanks in advance, I hope i'm not bothering you because of my many questions :)
- You are looking at a switching power supply where the small transformer helps bring down the voltage and isolates the output (we hope) from the 220. The output of a charger is very small and even smaller when at 220 so a large transformer is not needed and the rest of the electronics regulates the output voltage and perhaps limits the current as the device gets charged.
