An induction motor (Induction Motor) draws more current during start-up than during operation due to the electromagnetic characteristics inside the motor at the start-up stage. Here is a detailed explanation:1. High Current Demand During Start-Up1.1 Initial Flux EstablishmentNo Initial Rotor Field: At start-up, the rotor is stationary and has no initial rotating magnetic field. The rotating magnetic field produced by the stator needs to establish a magnetic flux in the rotor.High Induced Current

Electrical conduit plays a vital role in ensuring safe electrical installations. Here are several key reasons why electrical conduit is crucial:1. Physical ProtectionMechanical Protection: Electrical conduit protects wires and cables from mechanical damage, such as cuts, abrasions, and impacts. This is particularly important during construction and maintenance, especially when wires are installed within walls, floors, and ceilings.Environmental Protection: Conduit also shields wires and cables f

The working principle of surge protection devicesSurge Protective Devices (SPDs) are important safety devices primarily designed to protect electrical and electronic equipment from the effects of voltage spikes and surges. Here's how they work:1. Surge protectors in normal working conditionIn normal working conditions, surge protectors present high impedance to normal power frequency voltages, with almost no current flowing through them, equivalent to an open circuit. This means that surge prote

Modern dielectric oil breakdown voltage testers are instruments used to measure the breakdown voltage of insulating oils, such as transformer oil and switchgear oil.
