In a double wound transformer the secondary winding is always connected to?

To the load !


A measurement of 200 ohms is obtained between the primary and secondary of a double wound transformer is it safe to use?

When a resistance measurement is taken from both primary leads tied together to both secondary leads also tied together in a transformer, and the resistance obtained is 200 Ohms -- not safe in my book.


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 are the disadvantages of a double wound transformer?

There is no disadvantage with a current transformer -it does exactly what it's supposed to do, that is:reduce the current flowing in the primary circuit to a value that can be handled by its burden (ammeter or protective relay).electrically-isolate its secondary circuit from the primary circuit.


What is the difference between electronic and magnetic transformer?

All transformers are magnetic. A transformer is two (or more) coils of wire wound together. The varying magnetic field created by the primary winding induces a current in the secondary coils proportional to the ratio of the number of turns. You're probably refering to a switchmode powersupply as a "electronic transformer" (which is bad nomenclature, by the way). A switch mode supply actually contains a normal transformer in its core, along with circuitry to allow for a wide input fange and a narrow output range.

What is the difference between a wound and an injury?

The difference between a wound and an injury is that, when injured the skin is torn while a wound is what is formed after the skin is torn.


What is the difference between core type and shell type transformers?

The difference is between how the windings relate to magnetic material around which they are wound. If this magnetic material surrounds the windings then the device is said to be a shell type transformer. If the windings cover the exterior of the magnetic material then the transformer is said to be of the core type. Please see the link.

How do you convert a 110volt turbo oven to 220volt purchased in America you live in UK?

Buy a double wound step-down transformer (230/115 volts) of he appropriate capacity (kva) . You may have to replace the plug on your oven to match the output socket of the transformer if you buy this in England. Do not buy a single wound (auto transformer) as it can be extremely dangerous if it is wrongly connected.Alwyn.


What does the two lines indicates which are shown in between the winding of transformer?

They indicate the laminated metal core upon which the windings are wound.
