Q:What are the malfunctions and abnormal operation of the transformer?
Transformer failure: can be divided into the tank failure and tank failure. Fuel tank failure: a short circuit between the windings, short-circuit between the turns, direct grounding system side winding short circuit. Outside the tank failure: There is a short circuit between the casing and the lead wire and the ground short circuit (direct grounding system side). Transformer is not working properly: there are external faults caused by over-current, overload, oil level and due to over-voltage or frequency caused by over-excitation and so on. Line fault: phase short circuit (including three-phase short circuit, two-phase short circuit), two-phase ground short circuit, single-phase ground short circuit, transmission line disconnection.
Q:Rules for the operation of cooling devices for oil - cooled transformers
A, cooler should take their own independent dual power supply, and can automatically switch, when the work of power failure, automatically put into standby power, and issued a sound signal;  B, the transformer upper oil temperature reaches 55 ℃ or the current reaches 70% of the rated value, the auxiliary cooler automatically input;
Q:What does an isolated transformer output on a microphone splitter do?
This Site Might Help You. RE: What does an isolated transformer output on a microphone splitter do? I have a Whirlwind microphone splitter box with a direct out and a transformer isolated output. What's the reason for the transformer isolated output?
Q:How to use a multimeter to determine the quality of small transformers
Generally with the smallest ohm file to measure whether the primary tap, if not, then damaged. Use the X10K stall above the ohm stalls to measure the primary and secondary, primary secondary and iron core for short circuit or leakage. If there is connectivity, then the insulation is bad or has been burned or breakdown.
Q:incompatible step-up/down transformer and laser printer?
It's not quite clear how your battery charger and step up/down transformer are associated or if you tried to use the step up/down transformer to power the laser. I'm guessing you tried and it didn't work and now your step up/down transformer doesn't work either. Since you've exceeded the power output of the step up/down transformer by using the laser, one of several things may have happened: 1. there is a safety fuse that has been blown in the step up/down transformer 2. there is a built-in circuit breaker that has been tripped in the step up/down transformer 3. you've damaged the circuitry/wiring in the step up/down transformer permanently 4. if the battery charger was plugged in at the same time (theorizing it is a separate device) it may have been damaged by the low power available by the power draw of the laser that the step up/down transformer was trying to supply You should always verify the power requirements of equipment to that of the supply before using them together and remember to calculate for total power of everything that is plugged into the supply that is being used at the same time. It is recommended that laser printers should not be plugged into power strips or surge protectors unless they are specifically designed for that heavy of a power load as most are not. If you haven't already, try removing them all from power for a few minutes or a couple of hours and then try plugging them in one at a time to a standard wall outlet to see how they respond. I would have to see them all to evaluate specifically what was wrong. Best of luck.
Q:Two Transformers Parallel Operation
If the transformer voltage ratio is equal (equivalent to the equivalent of the induced potential), the impedance voltage (equivalent to the transformer internal resistance) are equal, then they output the current is equal, that is, the load is evenly distributed. The total capacity is the sum of their capacity. Otherwise, the impedance of the output voltage of the small current, its load rate is relatively high, when its load current reaches full load, the impedance voltage has not reached a full load, if the load at this time for the total Capacity, then the total capacity is less than the sum of the two capacity. This is a strict argument. In fact, the two transformers of the impedance voltage difference is very small, the load distribution is also very small difference, in addition, the so-called transformer is a little overload, nor is it so strict, so the actual total capacity and the difference between the two capacity Not big. In order to prevent the load distribution is too uneven, the capacity of these two transformers should be as close as possible, should not exceed 3: 1, because the capacity of the large impedance voltage is small, it has reached full load, and that small capacity is still in the owe Load, its role is not fully play out, it is not the significance of the parallel. The above is the answer 2009-10-8 02:31. At the end of the said, "the large capacity of the impedance voltage is small, it has reached full load, and that small capacity is still in the obvious underload, its role is not fully play out", wrong, apologize. Should be large capacity transformer impedance voltage, and small capacity impedance voltage is small, the load rate is high, the output current to reach full load, resulting in a larger capacity of the transformer can not put its big capacity advantage fully play out, this is Very unfavorable.
Q:100kVA above the transformer grounding resistance is how much
4.2.1 low-voltage power equipment grounding device grounding resistance, should not exceed 4 Europe. The use of the same grounding device parallel operation of the generators, transformers and other electrical equipment, when its total capacity does not exceed 100 kVA, the grounding resistance should not be greater than 10 Europe. Meaning is clear, that is, more than 100kVA, the grounding resistance should not exceed 4 oh ah.
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:volt converter/ transformer?

Q:what's a tv transformer?
That would be RARE for that model.they just don't fail on that model. MORE LIKELY it's the SPLITTER. or the 14 Volt Supply diode or the HORIZONTAL OUTPUT andthe Pincushion capacitor Almost as rare, is the main power output and the driver ic that gets whacked. Sometimes it's the driver ic's caps. Other times it's the 143 Volt Filter capacitor on the secondary side of the SMPS gets dried out, and the TV won't turn on.I've seen the DC voltage float around from 143 V up to 200 Volts when that cap dries out. Wow.LOOK at MY LIST of possibilities on your model. A good TV Tech can check them all.and find out WHY your TV is actually dead. MOST LIKELY the transformer isn't even bad.IN FACT I'd Bet MY PAYCHECK on it !!
