## Kirchhoff’s Current Law (KCL) Kirchhoff’s Circuit Laws

Kirchhoff’s Current Law (KCL) Kirchhoff’s Circuit Laws “Kirchhoff’s current law states that the algebraic sum of the currents that arrive at a point is equal to zero.” It is the sum of the currents that flow into a terminal is equal to the sum of the currents that leave it. …

## Kirchhoff’s Voltage Law (KVL) Kirchhoff’s Circuit Laws

Kirchhoff’s Voltage Law (KVL) Kirchhoff’s Circuit Laws “Kirchhoff’s voltage law states  that the algebraic sum of the voltages around a closed loop is zero.”  In a closed circuit, Kirchhoff’s voltage law (KVL) means that the sum of the voltage rises is equal to the sum of the voltage drops. In …

## What is an electrical corona effect in power system

Electrical Corona Effect Electrical corona effect occurs due to ionization of surrounding air around the conductor. The ionization of air results in distortion of electric field resulting in producing tiny electrical discharge. This electrical discharge is referred as corona effect. Engineering companies are trying to reduce corona effect because in …

## What is electrical proximity effect in power system

ELECTRICAL PROXIMITY EFFECT “Electrical proximity effect is the tendency of current to flow in undesirable patterns due to the presence of magnetic field generated by nearby conductor. “ When varying magnetic field conductors due to unequal distribution of current are placed close together. Eddy current induces in nearby conductor. Consider two adjacent conductors carrying …

## What is electrical skin effect in power system

ELECTRICAL SKIN EFFECT “Electrical skin effect is the phenomena that arises due to unequal distribution of alternating current over the cross sectional area of metallic conductor.” In other words, it is the condition in power lines when the concentration of charge electrons over the surface of conductor increases as compared to …

## What is an electrical eddy current

Electrical Eddy Current Electrical eddy current is the current that originates within the current carrying conductor by changing magnetic field due to Faraday’s law of induction. Eddy current circulates in a closed loop within the conductor, perpendicular to the magnetic field that generates it. It may generate when a conductor is …

## What is meant by an electrical stray current

Electrical Stray Current Electrical stray current refers to the flow of electrical current via two objects due to potential difference, imbalance or wiring flaws. Small voltage difference between two grounded objects in separate location may exist because of ordinary flow of current within the power system. However, large voltage difference can …
