What else can I help you with?
How are the two circuits of an induction motor similar to the circuit of a transformer?
They are magnetically coupled--a current in one circuit induces a current in the other one in both a transformer and an induction motor.
Can one intentionally short ct to one side of transformer?
yes........ we can short circuit the other side of the winding wen the primary is excited.... but we shouldn't apply rated voltage to the primary.. this method is used in the short circuit test of the transformer to find the parameters of the transformer.....
How do you carry open circuit test on power transformer?
A Linear power transformer coil? use an Ohm meter and check the resistance of the coils. No resistance is an open circuit. Also check for a cross circuit from one side of the transformer to the other.
Your transformer hums and reads 29.7 volts out and 0 out the other side then it pops and fries?
Sounds like a short circuit.
What is the difference between transformers and autotransformers?
A transformer or, more-properly, a mutual transformer, has two windings, the primary and the secondary, which are electrically-isolated from each other, with the secondary voltage induced through mutual induction. An autotransformerconsists of one tapped winding, so the secondary circuit is not electrically isolated from the primary circuit. An autotransformer may be used to either increase or decrease the primary voltage, depending how it is connected.
Why use a step down trans former when the lower voltage is available?
The secondary winding of a double wound transformer is 'floating' in that it is not referenced to any other part of the circuit. You choose how to reference it. You cannot accomplish this without a transformer.
What is the use of a transformer with turns ratio 1?
isolation if you are in the usa and must service electronics the neutral is grounded the power supply is a voltage doubler one side is 170v+ to ground the other is 170v negative to ground so if you run the power thru the transformer first you stand a better chance of staying alive these transformers are quite often used to trigger scrs or triacs for the same reason
ANti side tone circuit in telephone is used to?
The anti-sidetone circuit in telephone is used to suppress side-tone. The anti-sidetone circuit is an assemblage of transformers, resistors, and capacitors that perform a number of functions.The primary function is to reduce sidetone, which is the distracting sound of the speaker's own voice coming through the receiver from the transmitter. The anti-sidetone circuit accomplishes this reduction by interposing a transformer between the transmitter circuit and the receiver circuit and by splitting the transmitter signals along two paths. When the divided signals, having opposite polarities, meet at the transformer, they almost entirely cancel each other in crossing to the receiver circuit. The speech signal coming from the other end of the line, on the other hand, arrives at the transformer along a single, undivided path and crosses the transformer unimpeded. The anti-sidetone circuit also matches the low electrical impedance of the telephone instrument's circuits to the higher electrical impedance of the telephone line. Impedance matching allows a more efficient transfer of energy between the instrument and the line.
Is there adapters for 250 volt to 120 volts?
No. There are no "adaptors". To get 240V from a 120v supply you use a 120-240V step up transformer. <><><> Clothes dryers, water heaters and and other high-power 240 volt appliances cannot be run on a transformer from a 120 volt circuit. They must be powered from a separate branch circuit that has the right size breakers, cable and socket outlet to suit the appliance.
Why isolation transformer in forward converter?
Isolation transformers block transmission of the DC component in signals from one circuit to the other, but allow AC components in signals to pass.Transformersthat have a ratio of 1 to 1 between the primary and secondary windings are often used to protect secondary circuits and individuals from electrical shocks.
What cause other than circuit breakers would result in electricity failure?
loose neutral, bad main connection, depends on the exact situation could be a bad transformer
Advandage and disadvandage of berry transformer?
Berry transformer has good ventilation provision as compared to other types of transformer
