How do you connect ammeter with ct in single phase?
If it's a split-phase system with centre-tapped transformer, then two ammeters are needed, one on each side.
What is the role of magnetizing current in transformer?
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 )
What is the current of 1MVA transformer?
This depends on the voltage, and whether it is a three phase or single phase transformer.
What is phase angle error of current transformer?
The angle between the expected and actual secondary current is known as phase error.
How do you determine no load current and core loss of a single phase transformer?
It's easily done if you can measure the power drawn at the normal working voltage but with no load on the transformer (open-circuit secondary). All the power is core loss with the exception of a (very) small amount of resistive loss in the primary winding.
