If one transformer of a delta transformer bank fails the bank can be reconnected open delta and operate at reduced efficiency?
yes open all fuses close the primary neutral tap,remove secondary leads off of bad traansformer,tell customer to reduce his load until bad transformer can be replced.
Why would you use a three phase transformer in place of a single phase transformer?
the necesscity of two three phase transformers operating in parallel are as follows...if the one transformer fails to give supply,then another transformer can be used in parallel and hance,continuity of supply can be maintained.one transformer can be easily take out from the supply for repair & maintanance.if the load on the substation increases beyond the rated values of transformer, then another transformer can be used to share rhe load of the substation.
Which is a voltage tripler electronic device?
A voltage tripler (or doubler, quadrupler, etc.) is a network of capacitors and diodes arranged in series/parallel so that, when they filter an AC waveform, such as the output of a flyback transformer, they produce DC that is a multiple of the peak value. They are most often used to generate the high voltage needed for the anode of a CRT.
Why there is a phase shift of 30degree in Dyn11 3 phase transformer?
The phase shift is caused by inductance in the transformer. Any inductance from magnetic flux that fails to link both windings is called leakage flux, and the resulting inductance is called leakage inductance.
Can you use ordinary transformer in place of auto transformer?
yes we can place auto transformer in place of original transformer
What is a flyback inverter?
fly back inverter is such kind of DC-AC inverters which use the flyback transformer for the low dc-high dc stage of the inveter shortly it's DC to AC inverter with flyback transformer inside .
How do you discharge a flyback transformer?
you touch both of it's high voltage outputs together.
What is meant by LOT in CRT monitors?
its a line output transformer, also known as a flyback transformer, it provides the high votage required to run the tube. http://en.wikipedia.org/wiki/Flyback_transformer
If a television high voltage regulator opens what is the likely to be the symptom?
In most sets, the HV regulator actually regulates the B+ voltage to the horizontal output transistor and the flyback transformer. A bad regulator indicates high current or loss of horizontal drive. Check the flyback transformer, the HO transistor and also look for proper waveform and voltage from the horizontal driver transistor/chip.
What is a flyback?
A type of high voltage transformer. Their most common use was in CRT based TVs & computer monitors to generate the anode high voltage and horizontal sweeps.
Will a 6v flyback coil provide a shock free spark?
No. Atleast i have yet of have seen a flyback transformer that could produce a 50khz+ 0.1 amp spark. the effect your looking for can be produced by a low output Hand held Oudin/tesla coil Aka "violet ray" or "violet wand"
What is the function of TV flyback?
The TV flyback transformer is obsolete in modern television sets and is not used.In the old cathode ray tube (CRT) television sets the flyback transformer had two functions:generate a large and powerful current pulse to drive the horizontal deflection coil in the yoke around the neck of the tube to create a quick horizontal retrace between sweep linesusing a large secondary autotransformer winding produce a very high voltage (i.e. 15KV to 100KV) rectified by a high voltage diode needed by the anode of the CRT to accelerate the electron beam
Is a tv main and power and the flyback transformer the same thing?
the main or power transformer is your iron and copper variety to get all the voltages to supply various circuitry fly back is ferrite in a resonant tank on the 15Khz to get the 10Kv for the second anode of the crt
Can a flyback transformer be powered by nothing but a car battery and wires?
A transformer is an AC device in that it requires a changing current to be input in order to see an output. Attaching a 12V battery to the primary side of the transformer will generate a voltage on the secondary for a short amount of time. Once the primary current has risen to a stable level, there will be no output voltage on the secondary. There will also be voltages on the secondary and the primary when the battery is disconnected from the transformer. A flyback transformer relies on an AC current at the primary to generate a high voltage at the secondary output. Circuitry to make changes to the primary current will be needed in addition to the battery. Warning: removing the battery from the primary winding of the transformer is liable to generate a very high voltage across the primary coil as well as the secondary. In some cases, they can be lethal. Do not experiment with transformers unless you are properly qualified and supervised.
How to calculate short circuit protection for transformer?
don't overload it, have a look on the transformer their should be an input voltage and an output voltage if take fails just try and see if u can overload it when you do try and figure out the voltage and get a new transformer;)!!!!!
