A power system is a network of electrical components that generate, transmit, and distribute electricity to end users. The power system operates at a certain frequency, which is the number of cycles per second of the alternating current (AC) voltage and current. The most common frequencies used for power systems are 50 Hz and 60 Hz, depending on the region of the world. But why do we use these frequencies and not others? What are the advantages and disadvantages of different frequencies? And how

The extra high voltage transmission lines transmit huge amount of electric power. Hence, it is always desirable that the continuation of power flow through the lines should not be interrupted for a long time. There may be a temporary or permanent fault in the lines. Temporary faults get automatically cleared, and these do not require any attempt for fault rectification. It is normal practice by the operators that after each initial faulty tripping of the line, they close the line. If the fault i

Presently 3-ø AC system is very popular and being used worldwide for power generation, power transmission, distribution and for electric motors.Three phase system has the following advantages as compare to single phase system: Power to weight ratio of 3-øalternatoris high as compared to 1-ø alternator. That means for generation for same amount ofElectric Power, the size of 3-ø alternator is small as compare to 1-ø alternator. Hence, the overall cost of alternator is reduced for generation of sam

What is a Power System?An electric power system is defined as a network of electrical components used to supply, transfer, and consume electric power. The supply is done through some form of generation (e.g. a power plant), the transfer is done through a transmission (via a transmission line) and distribution system, and the consumption can be through residential applications such as powering the lights or air conditioning in your home, or via industrial applications such as the operation of lar

The connection of several generating stations in a network of particular transmission voltage level is commonly known as electrical grid system. By interconnecting different power generating stations we can solve various difficulties arise in power system. The structure, or “network topology” of a grid can vary depending on the the load and generation characteristics, constraints of budget and the requirements for system reliability. The physical layout is often forced by the geology and land av

Electrical substations constitute essential sections of the power distribution network, functioning as hubs for transmitting & distributing electricity. These complex facilities necessitate rigorous planning, design, &implementation to assure a consistent and efficient power supply.In this post, we will look at the foundations of electrical substation design, including different components, layout concerns, and environmental factors.Substation Planning CriteriaThe maximum fault level on
