Dielectric Materials A dielectric is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material as they do in a conductor, but only slightly shift from their average equilibrium positions causing dielectric polarization. Because of dielectric… Read More »
What is a Capacitor? Capacitor is a device that stores electric charge. A capacitor consists of two conductors separated by an insulator. Capacitors have many applications some of them include Computer RAM memory and keyboards, Electronic flashes for cameras, Electric power surge protectors and Radios and electronic circuits. Another definition of capacitor can be that… Read More »

Buchholz Relay Circuit is used for Transformer Protection, as we know there are many defects and dangers during the operation of power transformer that need to be addressed and necessary measures to be taken. Some of the hazards to transformer protection include overheating, over current and short circuiting etc. Another class of fault that causes a transformer… Read More »
What is a VFD? As the name describes VFD or Variable Frequency Drive is motor controller that drives an electric motor by applying the varying frequency and voltage to the electric motor that are used in the case where we need to change the speed of motors depending upon the load requirements. Other names for… Read More »
