Hi, i am currently analyzing a compound-type static exciter, which utilizes a potential transformerand a power current transformer (pictured below) . This current transformer is connected to the neutral side of the generator, and kicks in when large currents are flowing. Not much is known about this thing.
It has the following nameplate (located on the back!):
H 16-1-1
16-1-1
Z 2-1
2-1 Y3
(Y=pri/Z,H=sec)
Which actually makes some sense, because it is a multi-tapped transformer, specially tuned to the generator.
From how wires are connected we can derive the following winding configuration (viewed from the side of the transformer):
H Z Y Z H
18 3 3 3 18
The Z and H windings are put is series in a special way, which seems to derive the max amplitude.
I would like to derive the pri/sec phase and amplitude characteristics of the voltage and current (cos phi=0.8).
Does someone know anything about this type of transformer, or help me with deriving its characteristics?
