Parallel Operation of a Single Phase Transformer means that the two or more transformers having the same polarities, same turn ratios, same phase sequence and the same voltage ratio are connected in parallel with each other. The circuit diagram of two single-phase transformer A and B connected in parallel are shown below: Let, a1 is …

The Transformer is said to be in Parallel Operation when its primary winding is connected to a common voltage supply, and the secondary winding is connected to a common load. The connection diagram of the parallel operation of a transformer is shown in the figure below. The parallel operation of a transformer has some advantages likes …
The three-phase system has three live conductors which supply the 440V to the large consumers. While the single-phase system has one live conductor which is used for domestic purposes. The following are the main advantages of 3 Phase system over Single Phase system. Higher Rating The rating, i.e. the output of a three-phase machine is …
Polyphase System is a combination of two or more than two voltages having same magnitude and frequency but displaced from each other by an equal electrical angle. As poly means, many (more than one) and phase means windings or circuits. Each of them has a single alternating voltage of the same magnitude and frequency. The …
Parallel Resonance means when the circuit current is in phase with the applied voltage of an AC circuit containing an inductor and a capacitor connected together in parallel. Let us understand the Parallel Resonance with the help of a circuit diagram shown below: Consider an Inductor of L Henry having some resistance of R ohms …
Admittance method is used for solving parallel AC circuits. The admittance shows the reliability of the electrical circuit to allow the electric current to pass through it. First of all, we must know the meanings of some terms used in the Admittance Method. Admittance The reciprocal of the impedance of an AC circuit is known …
For solving Parallel Circuits, a number of branches are connected in parallel. Each branch contains a number of components like resistance, inductance and capacitance forming a series circuit. Each branch of the circuit is analysed separately as a series circuit and after that, the effects of each branch are combined together. For circuit calculations, the …
The source which supplies the active power to the network is known as the electrical source. The electrical source is of two types namely independent source and dependent source. The Independent and Dependent source means, whether the voltage or current sources are either depending upon some other source, or they are acting independently. Energy Sources …

A Source is a device which converts mechanical, chemical, thermal or some other form of energy into electrical energy. In other words, the source is an active network element meant for generating electrical energy. The various types of sources available in the electrical network are voltage source and current sources. A voltage source has a …
The Nodal Voltage Analysis is a method to solve the electrical network. It is used where it is essential to compute all branch currents.The nodal voltage analysis method determines the voltage and current by using the nodes of the circuit. A node is a terminal or connection of more than two elements. The nodal voltage …
