Difference Between Volts & Watts

One of the major difference between volts and watts is that the volt is the SI unit of potential difference and electromotive force, whereas the watt measures the SI unit of power. The other differences between them are explained below in the comparison chart. Both the volts and watts are related to each other. The …

Primary & Backup Protection

Primary Protection The main protection or primary protection is the first line protection which provides quick-acting and selective clearing of a fault within the boundary of the circuit section or element it protects. The main protection is provided in each section of an electrical installation. Backup Protection The backup protection provides the back up to …

Transposition of Conductors

Definition: The transposition is a physical rotation of the conductors so that the conductor is moved to take up the next physical position in the regular sequence. The transposition of the conductor equalises the mutual inductance and capacitance between the lines. The irregular spacing between the conductor gives a complex value of inductances which makes …

Sequence Impedance

The sequence impedance of the network describes the behaviour of the system under asymmetrical fault conditions. The performance of the system determines by calculating the impedance offered by the different element of the power system to the flow of the different phase sequence component of the current. Every power system component (static or rotating) has …

Sequence Networks

Definition: The sequence impedance network is defined as a balance equivalent network for the balance power system under an imagined working condition so that only single sequence component of voltage and current is present in the system. The symmetrical components are useful for computing the unsymmetrical fault at different points of a power system network. …

Regulating Transformer

Definition: The transformer which changes the magnitude and phase angle at the certain point in the power system is known as the regulating transformer. It is mainly used for controlling the magnitude of bus voltage and for controlling the power flow, which is controlled by the phase angle of the transformer. They provide the small …

Summation Current Transformer

Definition: The transformer which is used for converting the three-phase quantities into the single phase quantity is known as the summation transformer. This transformer is mainly employed for the unbalanced condition in the system and due to fault condition so that the relay operates properly. The connection of the summation current transformer is shown in …

Difference Between Diode & Transistor

One of the major difference between the diode and the transistor is that the diode converts the alternating current into direct current while the transistor transfers the input signals from the low resistance circuit to high resistance circuit. The other differences between them are explained below in the tabulated form. The diode is also known …
