Harmonics in power systems are unwanted frequency components that distort voltage and current waveforms. These harmonics cause numerous problems such as overheating, increased losses, resonance,
What is True Power Factor? The true power factor is the product of the displacement power factor and the distortion power factor. The displacement power
Transformers, even when not supplying any load, consume power—this is known as no-load loss or core loss. These losses occur as soon as the transformer
In the early days of industrialization, electrical systems mostly used linear loads—devices like three-phase induction motors, resistive heaters, and incandescent lamps. These systems drew a
What is Starting Torque of a DC Motor? The starting torque of a DC motor is the maximum torque that a motor can deliver to
In modern electrical systems, especially with non-linear loads, accurate measurement of AC signals is critical. This is where True RMS measurement outperforms traditional methods. Unlike
Definition: Breaking capacity or interrupting capacity of the circuit breaker is a crucial parameter for selecting the breaker for the electrical network. The short circuit
The accuracy class of a CT refers to the permissible error limits of the CT over a specified range of conditions. It ensures that the
The magnetization curve of the current transformer shows the relationship between the secondary excitation current and secondary excitation voltage. The equivalent circuit diagram of the
What is the knee point voltage of CT? The knee point is defined as the voltage at which a 10% increase in applied voltage increases the magnetizing current by 50%.
