Voltage Distribution Over Insulator String | Overhead Line Insulator

Voltage Distribution Over Insulator String-: Here, C=Capacitor f each unit/disc. kC=The capacitor of each joint to the earthed tower that can be assumed. We can easily find out string efficiency of ‘n’  number of an insulators by these formula. ∴ Capacitance to earth = k × self capacitance=kC ηs= String efficiency. v1 = Voltage across the […]

Types of Electrical Insulators | Overhead Line Insulators

Generally 3 types of electrical insulators are used as overhead insulator. But i will discuss here about of 4 types of electrical insulators they are-: Pin Types Insulators Suspension Types Insulators Strain Types Insulators Post Types Insulators Here neglecting the shackle & Stay type insulators, because they are used mainly for low voltage(400/230 V) application. Pin Types Insulators A pin type […]

Different Types of Electrical Cable

What Is Electrical Cable-: Electrical Cable is consisting of two or more wires, or conductors with their own insulation. Its wires are bonded, twisted or braided together. An electrical cable are more flexible by stranding the wires. Obviously maximum time we are used copper wires in a cable and it may be bare tin, gold, […]

Different Types Of Transformers

Electrical Transformers An electrical transformers is an A.C static piece of  equipment. That transfer electrical energy in one electric circuit is transform into electric energy of the same frequency in another circuit . Frequency it can increase or decrease the voltage with corresponding to decrease or increase of current keeping same power. The physical basis […]
