Fiber Optic Cable Types & What They Are Used For

What are Fiber Optics Cables Used For? Fiber optic cables (also known as optical fiber cable) are network cables that contain many strands of fine glass fibers known as optical fibers, which are kept well-insulated within the body of the cable. These cables are created for the use of long-distance,

Electrical Power System: What is it? (Power System Basics)

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

Electrical Grid System

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

Power System Stability

Power system engineering forms a vast and major portion of electrical engineering studies. It is mainly concerned with the production of electrical power and its transmission from the sending end to receiving end as per requirements, incurring a minimum amount of losses. The power often changes due

Transient Stability in Power System

The ability of a synchronous power system to return to stable condition and maintain its synchronism following a relatively large disturbance arising from very general situations like switching ON and OFF of circuit elements, or clearing of faults, etc. is referred to as the transient stability in p

Steady State Stability

As an introduction, we need to know about power state stability . It is really the capability of the system to return to its steady state condition after subjected to certain disturbances. We can now consider a synchronous generator to understand the power system stability . The generator is in sync

Fundamental Frequency And Harmonics: What Are They?

What Are Harmonics? Harmonics are defined as an unwanted higher frequency component that is an integer multiple of the fundamental frequency. Harmonics create a distortion in the fundamental waveform. Harmonics usually have a lower amplitude (volume) than the fundamental frequency. What is Amplitude

Admittance: What is it? (Formula & Admittance vs Impedance)

What is Admittance? Admittance is defined as a measure of how easily a circuit or device will allow current to flow through it. Admittance is the reciprocal (inverse) of impedance , akin to how conductance and resistance are related. The SI unit of admittance is the siemens (symbol S). To reiterate

Advantages of Bundled Conductors

What are Bundled Conductors? We can often see the transmission lines where instead of a single conductor per phase multiple conductors per phase are being used. A metallic structure called spacers groups the conductors of a phase. These spaces help to maintain a constant distance between the conduct

Bundled Conductors Used in Transmission Line

Single stranded conductors are used in transmission system usually up to 220 KV. But it is not possible to use single-stranded conductor for the voltage above 220 KV systems. For very high voltage system, hollow conductor can be used to optimize the flow of current through it. But erection and maint

Sag in a Transmission Line: What is it? (And How To Calculate it)

What is Sag in a Transmission Line? In a transmission line , sag is defined as the vertical difference in level between points of support (most commonly transmission towers ) and the lowest point of the conductor . The calculation of sag and tension in a transmission line depends on the span of the

ABCD Parameters of Transmission Line (Theory & Examples)

What are ABCD Parameters? ABCD parameters (also known as chain or transmission line parameters) are generalized circuit constants used to help model transmission lines . More specifically, ABCD parameters are used in the two port network representation of a transmission line. The circuit of such a t
