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 else can I help you with?
In a double wound transformer the secondary winding is always connected to?
To the load !
What is the difference between double wound transformer and an auto transformer?
A double wound transformer has two separate windings (primary and secondary) that are magnetically coupled, allowing for electrical isolation between the input and output circuits. In contrast, an auto transformer has a single winding that acts as both the primary and secondary, with part of the winding shared between them, which means it provides no electrical isolation. This design makes auto transformers more compact and efficient for certain applications, but they are less versatile in terms of voltage transformation and safety.
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.
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.
What causes a low voltage in the transformer?
If this refers to a wire wound transformer, as it sounds then there is likely only two possibilities : the input voltage has dropped prier to entering the primary windings or there is a short in the windings some where within.The only other possibility I can think of is : This is a trick question and the transformer is a step down transformer.
What are the advantages of double wound transformer over a auto transformer?
The difference between a double wound step up transformer and an auto transformer is the double wound on the step up transformer and the single wound on the auto transformer.
In a double wound transformer the secondary winding is always connected to?
To the load !
Three main parts of a double wound transformer?
Core Primary Winding Secondary Winding
Principle of operation of a double wound transformer?
they are to convert power into jeremy osborne, which in turn creates an aneesh karan
Diagram of a double wound transformer?
do exist! Is there a real question about d.w.t's? On a double wound transformer, the primary winding is isolated from and secondary winding, but still use the same common core.
What are two types of EMF induced in a double wound transformer?
1. self- induction2. mutual- induction
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 are the disadvantages of a transformer?
Takes quiet a bit of time to produce.
What is the difference between a 1.5KVA and a 3KVA transformer?
The 3 kVA transformer will weigh double the 1.5 kVA transformer.
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.
