Why secondary of current transformer is short circuited?

Secondary Current: Voltage across Ammeter: For this reason a current transformer should never be left open-circuited or operated with no-load attached when the main primary current is flowing through it just as a voltage transformer should never operate into a short circuit.

Likewise, people ask, what is the secondary voltage?

A transformer that increases voltage from primary to secondary (more secondary winding turns than primary winding turns) is called a step-up transformer. Conversely, a transformer designed to do just the opposite is called a step-down transformer.

What is a dual voltage transformer?

A dual voltage transformer can be defined as the one which is capable of providing two types of voltages i.e. if the two separate windings are connected in series, they will provide the sum of voltages supplied to the two coils and if the two windings are connected in parallel, then the net voltage will be decreased.
