Two port Network

-

 In two port network, their is pair of two terminals (i.e. total 4 terminals) electrical network. In each port current enters in one terminal and leaves through another terminal. figure of two port network is given below.


Driving point Impedance and Admittance Functions

  • Driving Point Impedance function
Z11(s) = V1(s) / I1(s)      and       Z22(s) = V2(s) / I2(s)

  • Driving Point Admittance function
Y11(s) = I1(s) / V1(s)      and       Y22(s) = I2(s) / V2(s)


Impedance and Admittance Transfer Function

  • Impedance Transfer function
Z21(s) = V2(s) / I1(s)      and       Z12(s) = V1(s) / I2(s)
  • Admittance Transfer Function

Y21(s) = I2(s) / V1(s)      and       Y12(s) = I1(s) / V2(s)


Voltage and Current Transfer Function

  • Voltage Transfer Function
G12(s) = V1(s) / V2(s)     and       G21(s) = V2(s) / V1(s)
  • Current Transfer Function
𝛼12 = I1(s) / I2(s)           and        𝛼21 = I2(s) / I1(s)



Different Parameters in two port network


  • Impedance Parameters / Z-Parameters (Open Circuit Parameters)
V1 = Z11 I1  +  Z12  I2                          V2 = Z21 I1  +  Z22  I2

Symmetrical =>     Z11 = Z22
Reciprocal     =>     Z12 = Z21


  • Admittance Parameters / Y-Parameters (Short Circuit Parameters)
I1 =Y11V1 + Y12V2                                 I2 =Y21V1 + Y22V2

Symmetrical =>     Y11=Y22
Reciprocal     =>     Y12=Y21


  • Hybrid Parameters / h-Parameters 
V1 = h11I1  +  h12V2                             I2 = h21I1  +  h22V2

Symmetrical =>      h11h22  -- h12h21  = 1
Reciprocal     =>      h12  = --h21 


  • Inverse Hybrid Parameters / g-Parameters

I1 = g11V1  +  g12I2                                 V2 = g21V1  +  g22I2

Symmetrical =>       g11g22 -- g12g21 = 1                                                                        Reciprocal     =>       g12 = --g21


  • Transmission Parameters / ABCD-Parameters
V1 = AV2  --  BI2                                     I1 = CV2  --  DI2

Symmetrical =>        A=D
Reciprocal     =>        AD --  BC = 1

  • Inverse Transmission Parameters / abcd-Parameters 
V2 = aV1  --  bI1                                      I2 = cV1  --  dI1

Symmetrical =>         a=d
Reciprocal     =>         ad -- bc = 1

Ideal Transformer (1-phase) Operation Under Load

 What is Ideal Transformer ? An ideal transformer is a transformer with the following assumptions: Permeability of transformer is infinite. Iron loss in the transformer core are zero. Resistance of transformer winding is zero. No magnetic leakage flux, so coefficient of coupling is  1 . Magnetization curve of transformer is linear. Operation of Ideal transformer under load Schematic diagram of an ideal, 1-phase transformer under load When a finite impedance load Z L   is connected across the secondary terminals of a 1-phase transformer as shown in above figure, the load current I 2   flows through the secondary winding and the load. load current I 2   is given by:- I 2  = V 2 / Z L How will MMFs Produce ? A voltage source V 1   is connected to the primary winding. Due to this voltage V 1  primary current I 1   flowing through N 1   number of turns in the primary winding produces an MMF  N 1 .I 1   which creates the flux Ⲫ in the core. This flux links with the secondary coil and induc

Compensating Winding

Compensating Winding The cross magnetizing armature reaction effect that causes concentration of flux under one pole tip is caused mainly by the conductors that lie under the pole are. When the machines are heavily loaded, the flux density at these tips become very high resulting in higher than normal induced voltage between concerned adjacent commutator segments. This may cause a spark over between adjacent commutator segments more so because these coils are physically close to the commutation zone where air temperature is high and favorable for spark over. This may lead to other segments also getting involved and resulting in fire over entire commutator segment. Also if load is rapidly fluctuating (e.g. rolling machine), L(di/dt) voltage of coils may became high enough to start a spark over between adjacent commutator segments. This phenomenon will start from the coil under the pole center and it would have maximum. This problem is more acute when load is decrea
