Transformer turns ratio is the ratio of voltages between two windings. For instance, a 24VAC control transformer that runs on 120VAC will have a turns ratio about 5 to 1.
The dc is supplied via a centre-tap on the transformer. This ensures zero dc net flux in the transformer core, which enables a much smaller core to be used.
RCT is Secondary resistance of Current transformer it depends on Design.
An ideal transformer (one with no losses, and not a bad approximation for the real thing) has an input power equal to its output power. In simple terms, since power is the product of voltage and current, then for a given value of power, as the voltage goes up, the corresponding current will go down.
It'll behave like a transformer on open circuit with a huge leakage reactance due to the very large air gap resulting from there being not rotor. So it will draw a largish reactive current from the supply.
Your stereo system has an internal transformer in the power supply that is designed to operate at a given frequency. If it is designed to operate at the load your stereo system will use at 50 Hz, then yes. Otherwise this transformer will overheat when connected at the wrong frequency, and will burn out. You might be lucky and the power supply may be labelled to operate at 50 or 60Hz; if not, I recommend contacting the manufacturer. A voltage transformer will convert 50Hz 220 to 50Hz 110. To change frequency, you need special equipment.
when dc supply is given to transformer at primary winding , the output at secondary winding will be zero.Because to induce voltage ,countnie changing flux is required ,that can not be obtained from dc supply...........
All transformers have a power rating given in kVA which determine the maximum load that can be connected to that transformer.
The supply is given on the high voltage side of transformer because the supply voltage required to circulate rated current through the transformer is usually very small So energy is saved.
The dc is supplied via a centre-tap on the transformer. This ensures zero dc net flux in the transformer core, which enables a much smaller core to be used.
RCT is Secondary resistance of Current transformer it depends on Design.
A winding is the name given each of the coils wound around the transformer's core. A basic transformer has two windings, termed the primary winding (connected to the supply) and the secondary winding (connected to the load).
If the narcissist regards you as a potential future source of narcissistic supply, he will seek to compromise. If he has given up on you as a source of supply - he will fight you tooth and nail.
Wire sizing of a feed conductor is based on the amperage that a device draws. To calculate amperage from KVA a voltage of the supply has to be stated. Without this voltage and whether the transformer is single or three phase an answer can not be given.
The "all day" efficiency of a transformer is defined as the ratio of energy out/energy in for a given all day cycle.
The Load will consume part of the power and therefore reduce the current (voltage ) available for the secondary part of the transformerAnswerYou cannot apply a load to the primary of a transformer which, by definition, is the winding connected to the supply voltage. Your question makes no sense.
An ideal transformer (one with no losses, and not a bad approximation for the real thing) has an input power equal to its output power. In simple terms, since power is the product of voltage and current, then for a given value of power, as the voltage goes up, the corresponding current will go down.
no, infinite voltage can't be given to the primary of the transformer....if the secondary is connected to the load, then over voltage will damage the load, if secondary is open circuited, then the infinite voltage can breakdown the transformer internal insulation,
