Why is equivalent circuit diagram important?

The equivalent circuit diagram of a transformer is a simplified circuit in which the impedance, resistance and leakage reactance of the transformer can be more easily calculated. The equivalent impedance of transformer is an important parameter to be calculated.

What types of equivalent are used in the circuit?

The most important types of equivalent circuits

• Series resonance circuit and impedance against frequency. The ideal capacitor Cs is influenced by the lead inductance Ls (of the order of several nH) and the track resistance Rs (typ.
• Parallel circuit and impedance against frequency.
• Tolerance space.

Why is equivalent resistance important?

The equivalent resistance is where the total resistance connected either in parallel or in series. Electrical resistance shows that how much energy will be required when we move the charges i.e. current through the circuit. If we need lots of energy, then the resistance necessary should also be high.

What is the use of equivalent circuit of transformer?

Equivalent Circuit of Transformer is an electrical circuit explanation of equations representing the behavior of that Transformer. In fact, an equivalent circuit of any electric instrument is important for the analysis of its performance and to discover any scope of further modification of modeling.

What is equivalent diagram?

Equivalent circuit diagram of a transformer is basically a diagram which can be resolved into an equivalent circuit in which the resistance and leakage reactance of the transformer are imagined to be external to the winding.

How do you find the equivalent circuit?

For a parallel circuit with three resistors, the voltage drop across each resistor equals the supply voltage. In other words, for a parallel circuit, the equivalent resistance is found by adding the reciprocals of the individual resistance values, and then taking the reciprocal of the total.

What is the equivalent circuit resistance?

The equivalent resistance is defined as a point where the total resistance is measured in a parallel or series circuit (in either the whole circuit or in a part of the circuit). The equivalent resistance is defined between two terminals or nodes of the network.

What is the value of equivalent resistance of the circuit?

The equivalent resistance is the algebraic sum of the resistances (Equation 10.3. 2): RS=R1+R2+R3+R4+R5=20Ω+20Ω+20Ω+20Ω+10Ω=90Ω. The current through the circuit is the same for each resistor in a series circuit and is equal to the applied voltage divided by the equivalent resistance: I=VRS=9V90Ω=0.1A.

Why the equivalent circuit of an induction motor and transformer is almost same?

The Induction motor is similar as a Transformer with a rotating short-circuited secondary. Both machines are works on the principle of electromagnetic induction. The equivalent circuit and vector diagram of both machines are almost the same. In the transformer, the electrical load connects at the secondary winding.
