Q:Flyback Transformer Clarification & help?
You might find whether your transformer is broken with an ohmmeter between the ultor cap and a pin by trying each with the meter set to a high ohms range, with (I think) the black meter lead connected to the ultor. If you don't see a result 1st. time around, try swapping the meter leads. If you get a result, try the 24V test there. If you don't, and using his method also fails, I think you have a dud. So far as the 9V test, I think that has a fatal flaw. A digital multimeter, or usually also an analogue one, cannot respond fast enough to a single pulse. A digital meter only samples at a certain rate, and if the voltage does not align with the sampling, you see nothing. Even if it does, I think you would only see an instantaneous reading before next sample sees nothing. Apart from that, the voltage spike will be well over 200V! The object is to sort out input direction in the primary. I would suggest you sort out the primary connections, and build the circuit. I have not looked at it, but I think if you fire it up, you will either have + HV coming from the ultor cap, or nothing. If nothing, reverse the primary. DON'T TEST IT WITH YOUR FINGERS!!!
Q:50KVA transformer each phase current maximum band
Transformer output power is apparent power, and active power (KW) relationship: apparent power = active power × power factor. With an average power factor of 0.8, the 50 KVA transformer can be the load power (50 KVA × 0.8) 40KW of active power. Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.

Q:What are the ways of protecting the transformer?
First, the gas protection: to protect the transformer internal short circuit and oil surface failure. Second, differential protection, current quick-break protection: to protect the transformer winding or lead-out phase of the phase-to-phase short circuit, large ground current system grounding short circuit and winding turn short circuit. Third, over-current protection: to protect the external phase short circuit, and as a gas protection and differential protection (or current quick-break protection) backup protection. Four, zero sequence current protection: protection of large ground current system external single-phase ground short circuit. 5, overload protection: to protect the symmetrical overload, only acting on the signal. Six, over-excitation protection: to protect the transformer over-excitation does not exceed the allowable limit.
Q:Low Voltage Transformer Problems?
Different kind of voltage. Did you switch your multimeter to read DC voltage? Most lighting ballasts are ac output (like fluorescent or metal halide). In the case of mr16 50w light bulbs typically power is 12v dc output from either an electronic or magnetic transformer. Magnetic is heavy iron with copper wound like a typical door bell transformer. Electronic is smaller and lighter using circuit boards to convert the voltage. In both cases it will be DC. Something else to consider is worn contacts where the bulb connects. And m16 bulbs don't last very long. Oil from your hands will shorten their lifespan even more. Also poor heat dissipation through the fixture. I've worked with a lot of the types of fixture you're speaking of. (usually 4 recessed cans but also pendants and track fixtures)

Q:Microwave transformer wires?
transformers is a movie, silly. your microwave is not an autobot, dont worry
Q:transformer windings?
Assuming that the transformer is designed for a primary voltage of 35 or more, then you can simply multiply the applied primary voltage (up to the design limit) by the turns ratio and this will give you the output voltage. In this case: output voltage 35 x 4500/355 444.
Q:What is the maximum current of the 800KVA transformer? What is the current? Is how to calculate, ask you master
The current of the transformer is determined by the load. 800KVA distribution transformer, the general high side is 10KV, low side is 0.4KV. Transformer rated current = capacity / (root 3 * rated voltage) 800KVA, high voltage side rated current = 46.2A. Low side = 1152A. Transformer has no load loss and load loss. When the no-load loss is equal to the load loss, the transformer is the most efficient. The general efficiency of the highest load in the 60 ~ 70% or so.
Q:How to make a current transformer more linear?
There could be eddy currents in a poorly designed transformer, yet sensible transformer cores are produced from laminated iron so as that the present can't circulate around the middle. you do no longer choose the middle to appear as if a shorted turn on the transformer. inspite of out eddy cutting-edge loss, there nonetheless is capability loss interior the middle that equals the part of the B-H loop according to cycle of ability.
