 Star-Delta connection




 Star-Delta connection is a type of three-phase electrical connection used in power transmission and distribution systems. It involves connecting the windings of a three-phase motor or transformer in two different configurations - the star (Y) configuration and the delta (Δ) configuration.

In the star configuration, the three windings of the motor or transformer are connected together at a central point, known as the neutral point. Each winding is also connected to one of the three phases of the power supply.

In the delta configuration, each winding of the motor or transformer is connected in a loop, with one end connected to the start of the next winding and the other end connected to the end of the previous winding.

The star-delta connection allows a motor or transformer to be started with reduced voltage, which can be useful in applications where a high starting current could damage the motor or cause a power outage. During the starting period, the motor is connected in the star configuration, which limits the current flow to one-third of the normal operating current. Once the motor is up to speed, it is switched to the delta configuration, which provides full voltage and current.

Star-delta connections are also used in power transmission systems to reduce the voltage drop and improve the efficiency of power transfer over long distances.

Television

  Television Television, often abbreviated as TV, is a device used for transmitting and receiving television signals. It is a popular form of entertainment and a primary source of information for many people around the world. The first electronic television was invented in the 1920s, and over the years, television technology has advanced significantly. Today, televisions come in a variety of sizes and types, including LCD, LED, OLED, and plasma screens. Television broadcasting has also evolved over time, with the advent of cable and satellite TV providing viewers with access to hundreds of channels. In addition to traditional broadcasting, streaming services like Netflix, Hulu, and Amazon Prime have also become popular, allowing viewers to watch TV shows and movies on demand. Television programming includes a wide range of genres, including news, sports, drama, comedy, reality shows, and documentaries. Many TV shows have become cultural icons and have played a significant role in s...

Integrated Circuit IC stands for Integrated Circuit, which is a miniature electronic circuit that is made up of multiple components such as resistors, capacitors, transistors, and diodes that are etched onto a small piece of semiconductor material (usually silicon). The components are interconnected by thin metal wires and the entire circuit is encapsulated in a small package made of plastic, ceramic, or metal. ICs were first developed in the 1960s and have since become a fundamental building block of modern electronics. They offer several advantages over traditional circuits built using individual components such as smaller size, lower power consumption, greater reliability, and lower cost. ICs are used in a wide range of electronic devices such as computers, smartphones, televisions, and many other consumer electronics products. There are many different types of ICs that are designed for specific applications such as analog circuits, digital circuits,  microprocessors, memory chi...
