2. General

Over a century, principle of power transformer has not ever changed, but as time progressed, the advanced production facilities are getting perfected, the transformer with amorphous alloy core produced by our company adopts new magneto conductive material, i.e. amorphous alloy core. The no-load loss of this kind of transformer is 80% lower than that of stalloy cored transformer, and so does the no-load current. It is the most ideal distribution transformer in energy saving at present, especially suitable for the rural power grids and the developing districts, where the load factor is rather low. The amorphous alloy cored power transformer has advantage of low no-load loss, energy-saving and environment-protection, and it is fully in accordance with the national industrial policy” resource-saving, environmentally-friendly, and the establishment of reef society". The oil immersed transformer also has the ability to reduce the CO, SO, and NOx dioxide emissions of harmful gases. and therefore it is tiled as "green material" of 21st century.

Q:Is the upper oil temperature of the transformer high or lower?
Of course, is the upper high, thermocouple generally installed in the top.
Q:Transformer input power how to ask?
Transformer Efficiency = Output Power / Input Power * 100% The input power of the transformer will be larger, and the output power is the power difference of the input power minus the loss. Or the input power of the input power transformer plus the sum of the transformer losses. If you know the efficiency of the transformer, then the input power is the transformer output power and transformer efficiency ratio. General small capacity transformer, the efficiency of about 90%, large capacity transformer, the efficiency of 98%. Each motor system consumes two power, namely the real useful work (called kw) and the reactive power. The power factor is the ratio between the useful power and the total power. The higher the power factor, the higher the ratio between the useful power and the total power, and the system is more efficient.
Q:grounding transformers?
The steel body of the transformer and the neutral (wye point) should be bonded to a suitably installed and tested rod or mat by a cable capable of carrying the fault current that could occur. The wye point, in some cases, may be connected through a fault limiting resistor but this involves extra protection equipment and proper coordination. The actual type of ground depends on local conditions. A simple rod may be used in conditions where the ground has low resistance, a mat or multiple rods may be used in others. The resistance of the ground should be tested to meet local codes (usually 5 or 10 Ω). Since the design involves engineering and knowledge of national and local codes, it is best to have this done by a reputable engineering company.
Q:Am I overloading this electrical transformer?
Three phase transformers are given a power rating which is the sum of all three powers on each phase. So 285 amps on each phase at 120 line to neutral (assuming this is how youve them connected) is about 35kva, so about 100kva all up. What is actually on the name plate of the transformer? How hot is 'pretty hot'? Is it running as it was desinged (oil, dry, forced air cooling etc). Also how are your lamps/dimmers wired? The other answer is correct, the dimmers will produce alot of harmonics. The meter your are using to read the current is most likely designed to read a 60hz sine wave, any other stuff there will cause a wrong reading (they usually measure the average value, then apply a correction factor to obtain the rms value. But this factor depends on the wave shape, if its not a sine wave it will be wrong). See if you can obtain a meter that will measure the true RMS current. Transformers of that size are usually heavily over engineered, it should be fine as long as the tempertature doesnt continue to increase, ie to the point where the case is too hot to touch. As the other answer said it is probably rated for continuous operation at about 75 degrees. Id not worry too much as long as the temperature doesnt continue increasing.
Q:Transformers of the three transformations are the three?
Take a 10kV / 0.4kV, d / yn11, 100kVA transformer rated voltage full load operation: 1, the high side of the 10kV into the low side of the 400V; 2, the high pressure of 5.77A into low pressure side of 144.4A;
Q:What is the meaning of the Y D11 on the transformer?
Transformer Y / D11 Y ----- primary side connection, star type, D secondary side connection, triangle 11 is the primary and secondary side of the phase difference of the side line voltage lag secondary side 330 degrees (or lead 30 degrees).
Q:What are the serious consequences of transformer circulation?
The connection group number must be the same, the wiring group is different, the transformer secondary voltage phase is different, at least 30 °, the voltage difference will be a great circulation, burn the transformer.

Q:Three-phase transformer how four ways to connect it?
If the three-phase transformer has four windings can not have four kinds of wiring way?
Q:Transformer wire color codes?
Raptor gave good info. I would add just a few points: 1. The high voltage winding usually has the smaller gauge wire. 2. The high voltage (primary) winding also usually has a higher DC resistance and fundamental frequency impedance than the secondary. 3. Be sure to scrape the insulation off the wires before checking the resistance. Many years ago, an idiot I was working with didn't recognize that the wires had enamel insulation on them, and connected the transformer backwards. It was a 480 V / 1 V (or so) instrument transformer. We lost a lot of good equipment and nearly lost people because of that screwup. The recorder saw 2 kV before it died.
