ELECTRICAL POWER SYSTEM
Explore the core of generation, transmission, distribution and protection system of electrical power system
Generation system
First generate electricity with different sources like Thermal power plants, solar power plants, wind power plants, hydro electric power plants.
Transmission system
Transmit the voltages from generating station to grid station. Grid step up the incoming voltages into different category.
Distribution system
Receiving high voltages from transmission system and then step down the voltages as per rrequirement.
Protection system
Protect the entire electrical power system from generation to distribution system for reliable and save operations.

Transmission & distribution system
Today modern world where electricity powers almost every aspect of human life from homes and industries to hospitals and communication network. An efficient and reliable transmission and distribution system is the backbone of any electrical power system.
It involves the large scale movement of electrical energy from power generating stations (such as thermal, hydro, nuclear or renewable power plants) to substations near populated areas. This is usually at high voltage to minimize energy losses.
Importance of power system protection
Reliability
Electrical power systems are complex that generate, transmit and distribute electricity to consumers end. It is very important to ensure continuous and reliable supply of electrical energy. For reliable and save operation of electrical power protection system it is very important to maintain the safety reliability and efficiency of electrical infrastructure.
Prevent equipment damage
Electrical faults such as short circuits, overloads, and ground faults can generate extremely high currents and voltages. Without the protection system this can cause irreversible damaged to generators, transformers, cables and switchgear. Fast and accurate faults detection and isolation protect valuable assets.
Enable fast operation
Protection relays and circuit breakers work together to detect and clear faults in milliseconds. This speed is very important to prevent cascading failure tha can lead to entire blackouts or damage to multiple components in the system.
