Why are electrical power transmission lines always sagging   Why are electrical power transmission lines always sagging Controlled sagging in the transmission line is a crucial engineering consideration that works to balance the dynamic forces affecting electrical power transmission lines. What is the main reason behind sagging in electrical power transmission lines?   Why do we need sag in electrical power transmission lines:  Sag has an essential role in protecting power transmission lines from excessive electrical tension. This is why the electrical conductors are not connected in a way, but rather they are allowed to sag. Sag in power lines   In fact, the sag in high-tension transmission conductors contributes to maintaining the electrical energy transmission system for a long-term period, in addition to protecting it in the event of expansion or contraction. Therefore, the sag rate is carefully set and carefully studied, balancing between safety, temperatur...

Why is a capacitor placed in a single phase motor Why capacitor is required for single phase motor When operating a single-phase electric motor, the torque is somewhat weak in addition to the voltage fluctuations from the single-phase power source, so it is necessary to place an electrical capacitor called a run capacitor, which enhances the motor’s torque and also contributes to overcoming the voltage fluctuations (  monophase).   How to place a capacitor with a single-phase electric motor:  The electric capacitor is connected in series with the starting coil of the motor, and therefore the motor has no torque and thus the single-phase electric motor does not start without the starting capacitor.  Do not forget also that electrical capacitors improve the power factor of the engine (energy loss) by adjusting the electrical current and increasing the starting power.  In conclusion, electrical capacitors play an important role in the operation and efficiency of ...

Why are electrical transformers measured in KVA and motors in KW   Why are electrical transformers measured in KVA and motors in KW Welcome to the Electron Tips website. In this topic, we will learn about the reason for measuring electrical transformers in the unit KVA (kilovolt-ampere) and electric motors in the unit of kilowatt (KW).   Why electric motors are measured in KW:  An electric motor is an electrical device that consumes effective electrical power, which is why it is expressed in units of kilowatts or horsepower because it expresses the amount of electrical energy that the motor has benefited from, and it means the actual power used for mechanical purposes and expresses the actual performance of the electric motor (effective power), because  Inefficient power will do nothing for the electric motor.   The reason for measuring electrical transformers in KVA:  Electrical transformers' primary role is to convert electrical voltages, as they do not ...

What Are Those Balls That Hang on Power Lines Why are balls placed in electrical power transmission wires  Electricity is considered an essential part of our daily life, as it is responsible for operating most of our household and industrial appliances as well.  This enormous electrical energy is transmitted from power generation stations via electrical lines that bear high pressure and are often made of aluminum (why are aluminum wires used instead of copper?  In electricity transmission, balls are often placed suspended in the electrical power transmission wires.  Why are these balls placed?  What is its benefit: We will learn the answers to these questions in this educational article , There are several reasons for placing suspended balls in electrical power transmission wires, as follows:   The first reason: improving the performance of electrical networks  Suspended balls contribute to improving the performance of electrical networks by reducing v...

Why Is A Capacitor Used in A Ceiling Fan   Why do ceiling fans have a capacitor You may have noticed that ceiling fans contain an electrical capacitor, or sometimes two. What is the function and role of the electrical capacitor in ceiling fans?  What types of capacitors are specifically installed?  In this brief educational article, we will learn why capacitors are placed in ceiling fans.   Why is the capacitor placed in the ceiling fan( Start Capacitor) :  The capacitor is an electrical element that allows energy and electrical charges to be stored and discharged when the supply source is disconnected. Thus, it is placed in ceiling fans, which originally contain a single-phase induction motor, as it provides them with the energy necessary to rotate the fan blades and increase the torque through a single magnetic field.  Rotating, in addition to creating a forward angle between the two fan coils (the primary coil and the additional coil). What type of elect...

  Why Does an Electric Tester not Work on DC Current Why does the Tester not work on DC Current  In this educational topic, we will learn why the alternating current detector, or so-called tester, does not work on direct current. First, let us learn about the components and definition of the tester and its working principle.   Definition of AC detector tester:  The tester is a screwdriver available in different sizes with a glowing neon lamp inside. It is used to detect the alternating electrical current in the wires and the electrical outlet (the socket) to identify the Vase and Neutral wires in household electrical installations.   AC detector components:  The AC detector or tester consists of several components inside it, and the following picture shows its various basic components:  Screwdriver body.  Glowing neon lamp.  Metal rod. AC tester components  Why doesn't the AC power detector work on the DC power tester:  The reason i...

Ferrite bead   What is the circular piece you see on a computer charger cable (Ferrite bead)  The computer charger cable contains a cylindrical piece close to the head of the laptop charger, or even in some phones and other electronic devices. What is the role of this cylindrical piece?  Why is it put in the charger?   Name of the part and its function in the Ferrite bead charger:  This piece is called a Ferrite bead and is known as the iron filter or EMI magnetic interference filter, It is an essential part of the computer charger cable.  Its main role is to protect electrical signals from interference resulting from magnetic interference.

  Why are high-voltage lines used to transmit electricity Why are high-voltage lines used to transmit electricity Welcome to the Electron Tips website, and in another paragraph of the question and answer, the question of this topic is: Why are high-voltage lines used to transmit electricity instead of low-voltage ones?  The reason for using high-voltage lines in electrical power transmission lines is due to several reasons, including:   Reduce energy loss:  The use of high-voltage electrical power transmission lines means very thin electrical wires, which contributes to reducing energy loss as the electrical voltage is raised and thus there is an electrical current, and this reduces energy loss due to the resistance of the electrical wires.    Low cost:  To transmit electrical energy over long distances, the electrical voltage is raised using electrical transformers while maintaining the same capacity. This helps reduce the cost of electrical cables, u...
