As internet users continue to increase annually, the potential attack surface for hackers also rises. To keep ahead of the curve, it is essential to understand the most recent cybersecurity developments. The rising use of artificial intelligence (AI) by both attackers and defenders is one of the most notable trends. AI can be used to …
Electric motors are subject to a variety of stresses and disturbances. A portion of the disturbances is attributable to external factors, such as over- and Undervoltage, over- and under frequency, harmonics, unbalanced system voltages, and supply disruptions, such as autoclosing in the supplying network. External disturbances might be caused by motor dirt, cooling system and …

Any electronic system has its own frequency bandwidth (limit to the highest frequency of the signal), and the frequency characteristics reflect the essential characteristics of the electronic system. The filter is an engineering application circuit designed according to circuit parameters’ influence on the circuit’s frequency bandwidth. Everyone knows that there are many filters, and the easiest way …

1. Resistance When current flows through a conductor, the conductor’s internal resistance property to hinder the current flow is called resistance. The components that play a blocking role in the circuit are resistors or resistors for short. The primary purpose of the resistor is to step down, divide or divide the current, and it is used as …

The root cause of harmonic generation in power systems is non-linear loads. When the current flows through the load, it does not have a linear relationship with the applied voltage, and a non-sinusoidal current is formed, thereby generating harmonics. The harmonic frequency is an integer multiple of the fundamental frequency. According to the analysis principle …

Series reactors are primarily employed for current limitation and impedance enhancement. Some of the functions they serve include current limiting and neutral/earthing as well as motor starting and arc furnace series reactors. They can also be used in a duplex reactor configuration. Below we have discussed what are the precautions to be taken during the …
Inductors are components that convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer but with only one winding. An inductor has a specific inductance, it only resists changes in current flow. If the inductor has no current flowing, it will try to block the current …
Simply speaking, a device that requires energy (power) power is called an active device, and a device that does not require energy (power) power is a passive device. Active devices are generally used for signal amplification, conversion, etc., and passive devices are used for signal transmission, or “signal amplification” through directivity. Capacitance, resistance, and inductance are passive …

What is a reactor Usually, the resistance of capacitance and inductance to AC in the circuit can be called reactance, and the symbol is represented by X. What is a reactor? Some people in the industry also call it an inductor. When a conductor is energized, it will cause a magnetic field in a certain space it …

Introduction to Reactor Reactors are also called inductors. When a conductor is energized, it will generate a magnetic field within a specific range of space occupied by it, so all current-carrying electrical conductors are inductive in a general sense. But the inductance of an energized long straight conductor is small, and the magnetic field it creates …
