Magnetic Reluctance: Meaning, Formula, SI Unit, and Electrical Analogy
Magnetic reluctance is the opposition to magnetic flux in a material, similar to electrical resistance in a circuit. It is a key parameter in magnetic
Basics
What is Self Inductance? Definition,Formula, and Explanation
Definition: Self-inductance is the inherent property of the coil that opposes variation in the current passing through it. The coil opposes the change of current
Difference between Rated,Nominal and Operating Voltage
In this post, we will discuss the difference between rated, nominal, and operating voltage. Operating at the designed operating voltage enhances the equipment’s life. There
Electrical Insulation Classes | Classification of Insulating Materials
The life of electrical insulating materials gets adversely affected by the rise in temperature. Average insulation life gets halved for every 10° C increase in temperature. Therefore, the classification
What is Hysteresis Loop? Its Importance
A hysteresis loop is a graph in a four-quadrant that shows the relationship between the induced magnetic flux density B and the magnetizing force H.
Harmonic Restraining in Differential Protection
Harmonic restraining in differential protection is a technique used in transformer protection to prevent false tripping during inrush or over-fluxing conditions by detecting and blocking
Why Power in Pure Inductive and Pure Capacitive Circuit is Zero?
This article describes why the power in pure inductive and capacitive circuits is zero. The inductors and capacitors are the basic building blocks of an
Difference Between Ohmic and Non-Ohmic Conductors
💡 Key learnings: Ohmic Conductors: Obey Ohm’s Law; current is directly proportional to voltage. Resistance remains nearly constant under normal conditions. Non-Ohmic Conductors: Do not
Why Motor Rated in KW instead of KVA?
A motor is rated in kilowatts (kW) because its primary purpose is to produce useful mechanical output power to drive a load. Kilowatts represent the
Difference Between kVA and kW – Explained With Formulas & Examples
💡 Key Learnings: kW (Active Power): kW measures the real power consumed by electrical equipment to perform actual work. kVA (Apparent Power): kVA represents the
