CT(Current Transformer) is used to measure current flowing in the circuit. Current can be fully drawn or sensed in series condition. That's why , it is connected in series.
In parallel , the current is divided; and hence the total current cannot be measured)
The output of a current transformer must be shorted. Otherwise it will not operate in current transformer mode and it could potentially generate dangerously high voltages.
Nothing stops you from connecting the inputs of two current Transformers in series. They would simply measure the same thing.
The transformer itself does not pull current. Whatever you connect to the transformer pulls current. Whatever the output voltage of the transformer is, divide that into 600 and you get maximum current possible without burning up the transformer. At 24V that's 25 amps.
An ELSP is a current limiting fuse used in series with the primary fuse of a transformer.
In DC, flow of current is controlled by resistance only where as in AC it is done by Impedance which is combination of Resistance , inductive and capacitive reactances.Reasons:In transformers resistance of the transformer's core windings are very low due to which if you will connect transformer across DC supply then it will draw a heavy current which will burn out is winding and it may damage the equipment too.Transformers works of the principal of Induction (Mutual/Self) that is possible in AC only because in DC there is no induction therefore even if transformer's windings anyhow withstand with DC there will be no voltage output at output terminals of the transformer, therefore it is useless to connect transformer on DC supply.
You mean ac coil, the secondary coil, of a transformer? Then for the purpose of rectification, that is , for changing ac into dc, a diode is connected in series with the secondary coil of the transformer.
Series connect it within the line of the circuit for which you are interested in measuring the current flow.More detailSince we measure the flow of current IN the circuit, the ammeter must be connected in series with the part of the circuit for which you are interested in measuring the current flow.One of the ammeter's terminals must be connected to a point of the incoming current flow and its second terminal must be connected to the point of on-going current flow. To do this, cut the relevant circuit wire and connect one terminal of the ammeter to each end of the cut.
You use three CTs, one per line conductor, each feeding a separate ammeter,
Yes
current increase in series operatio and transformer will b damaged

connect 3 - phase supply to transformer primary winding.....keep transformer secondary winding open..... apply 3-phase voltage i.e.400v ac, and measure the amount of current flowing in each phase of the transformer primary winding...this current is the transformer magnetising current..... we can keep multimeters in series with the source....so we can measure directly the current readings.....(keep multimeters in current mode, and generally magnetising current will come in terms of milli amps for 400 v )

Current sources should not be connected in series. It's okay to connect them in parallel.
Alternating current or direct current? For doubling the AC voltage, use a 1 to 2 step up transformer. For doubling the DC voltage use 2 of the 12 V car batteries und connect them in series.

Measuring No-LoadIn theory the no-load current of a transformer is zero. But in practice there is iron loss and core loss in the transformer, so there is power loss. Connect an ammeter in series with the stabilizer to measure the no-load current. Check your energy meter at no-load to see how much power is consumed. Ohms law: I(Amps) = E(voltage) divided by R(resistance). In the case of coils (transformer), the resistance of the coil would simply be the total impedance (Z). If I am remembering this correctly, you get, I=E/(R+Z)
Reduce current - reduce power.
