Product Description:

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 +20and 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,

Q:Single bus sub-section for power distribution, transformer with a prepared and dual-use how to understand
One with a prepared, you can only put one of the transformer, any of its transformers can all the load to bring all the general into the line breaker and bus in the breakdown of the circuit breaker, interlock between the three, A change vote, B variable can not vote, or vice versa, B cast A can not vote. This is the nature of the load mostly for a load, power supply is necessary for high reliability, but also the largest investment. Dual use can be divided into several, mainly refers to the change can be put into use, and some can be put into the parallel use, in some cases is not allowed to use in parallel, is the three circuit breakers with interlocking Three locks two spoons, three circuit breakers can only vote two. At the same time the capacity of the transformer is also different, some are prepared, some are dark spare, the specific use depends on how the original system design. hope this helps.
Q:Transformers.?
A step up transformer has 5,000 turns in the secondary coil and 200 turns in the primary coil. N1 200 turns N2 5000 turns The primary is supplied with alternating current with an effective voltage of 900V. V1 900V (A) V2 ? V2 N2 / N1 x V1 V2 5000 / 200 x 900 25 x 900 22,500V (B) I2 20A ; I1 ? V1 x I1 V2 x I2 I1 (V2 x I2) / V1 I1 (22500V x 20A) / 900V I1 500 A (C) P1 ? P1 V1 x I1 P1 900V x 500A 450,000W (D) P2 ? P2 V2 x I2 P2 22,500V x 20A 450,000W Yep, the power in the primary is equal to power in the secondary.
Q:why doesn't the emf induced in the primary of a transformer does not cancel out with the supply voltage?
Leaving aside the double negative, the problem is your use of cancel - what do you expect - that it will go back to the generator and kill it? The transformer produces an output voltage which tries to do work against a resistance or inductance - the work it does produces a back EMF which the supply voltage works against so the generator has to do work. If there were no EMF in the primary, it would behave like a short circuit and blow the circuit - which is does in a small scale in the starting surge that you have to allow for when turning on equipment.
Q:What is the principle of the conversion of the transformer? How to restore the secondary side to the primary side?
3. The sum of the current: I2 '= I2 / k 4. The sum of the impedance: r2 '= k ^ 2 * r2 x2' = k ^ 2 * x2
Q:What is transformer reverse charging?
You can explain the specific situation, your multi-power situation is what kind of situation, because we have not seen you refer to the "book"
Q:Electrical transformer coiling questions.?
magnetism or magnetic field does not have a direct relationship with voltage. In a basic transformer, there are two coils. If your source is 110 volts on the input coil, and there are 100 turns of wire in the input coil and 200 turns in the output coil, then the voltage across the output coil will be 220 volts. This is because the turns ratio, (number of turns in output coil divided by number of turns of input coil) 200 / 100 2. And output voltage is equal to input voltage, multiplied by the turns ratio. Therefore, considering a second transformer with an input coil of 50 turns and output coil of 100 turns, the turns ration is still 100 / 50 2. Therefore if this transformer were connected to the same 110 volt source, the output 110 * 100 / 50 220 volts, same as for the first transformer. In a practical sense, many common small power transformers are designed with one turn of wire per volt. But this design also reflects the mass of silicon steel that is used in the design of the core which is also a very important part of the transformer design.
Q:How much excess power do transformers draw?
Transformers are generally 85% efficient. But for no load applications, series in an ammeter and you'll know the answer for a specific transformer.
Q:What does an isolated transformer output on a microphone splitter do?
Microphone Splitter Box
Q:If the secondary coil contains more loops than the primary coil ( Ns Np) we have a sep-up transformer?
A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors—the transformer's coils. A varying current in the first or primary winding creates a varying magnetic flux in the transformer's core and thus a varying magnetic field through the secondary winding. This varying magnetic field induces a varying electromotive force (EMF) or voltage in the secondary winding. This effect is called mutual induction. If a load is connected to the secondary, an electric current will flow in the secondary winding and electrical energy will be transferred from the primary circuit through the transformer to the load. In an ideal transformer, the induced voltage in the secondary winding (Vs) is in proportion to the primary voltage (Vp), and is given by the ratio of the number of turns in the secondary (Ns) to the number of turns in the primary (Np) as follows:- Ns/Np Vs/Vp ---------------------(i) By appropriate selection of the ratio of turns, a transformer thus allows an alternating current (AC) voltage to be stepped up by making Ns greater than Np, or stepped down by making Ns less than Np.
Q:How Sick Was Transformers?
I was pissed It ended way to soon!?!?!? I realize it was a rather long movie but after 20 years I needed another few hours. I desperatly await a number two, And they better make it.
