Why Is A Transistor Called A Current Control Device? A transistor is called a current controller because it can control the flow of current through it by controlling the current flowing through its base terminal. This is called “current boost” because the current flowing through the base terminal can be used to control a much
What Is A Trivector Meter? Where Is It Used? A three-vector meter is a type of energy meter that can measure active, reactive, and apparent power as well as the energy of the electrical energy source. It can also measure peak demand, power factor, supply voltage, and current. Tractor meters are used for commercial and
What Is The Meaning Of DYN11 In A Transformer? DYN11 is a notation that describes a group of transformer vectors. The vector group indicates the configuration and phase angle difference between the primary and secondary windings of the transformer. The file consists of four parts: The first part is a capital letter that indicates the
What Is Power Angle In Transmission Line System? The power angle in a transmission line system is the angle between the voltages at two different points (or buses) in the system. It is also called the load angle or torque angle. The force angle affects the amount of force that can be transferred between two points. The larger the power angle, the greater the power transmitted up
What Is The Difference Between Earthing And Grounding? Grounding and earthing are two terms that are often used interchangeably but have different meanings and purposes in electrical engineering. Grounding is the connection of direct current-carrying parts of electrical devices to the earth, for example, the metal housing or housing. This is to provide a safe
Why Generator Is Rated In Kva And Motor In Kw? Generators and alternators are rated in kVA because they produce both active and reactive power, expressed in volt-amperes (VA) rather than watts (W). The most important factors considered by manufacturers when designing electrical and power equipment such as transformers, UPS, alternators generators, etc. are the
What Is The Purpose Of AuxiliaryTransformer In Substation? An auxiliary transformer is a type of transformer used to power the auxiliary equipment of a substation, such as B. Lighting, heating, ventilation, air conditioning, battery charging, switchgear operation, switchgear drives as well as control and protection systems. auxiliary transformers are typically step-down transformers that step down
How To Check Earthing And Voltageat Home With Multimeter? To check your home’s grounding with a multimeter, you can follow these steps:
What Are Those Balls That Hang On Power Lines? These balls are called air marker balls or visual marker balls. They are placed on power lines as a visual warning signal to help low-flying aircraft avoid contact with power lines. The Federal Aviation Administration (FAA) requires power line spheres to appear on cables spanning canyons,
Why Capacitors Are Used In Power Factor Correction? Capacitors are used in power factor correction because they help improve the power factor by relieving the reactive power line. The capacitor achieves this by storing the remagnetization energy.Thepower factor correction uses capacitors connected in parallel to counteract the effects of inductive components and reduce the phase
