Series reactors are used in transmission lines to limit the flow of current and improve system stability.
Series reactors are used to limit the flow of current in a transmission line.
They improve system stability by reducing voltage fluctuations and power surges.
They can also be used to compensate for line capacitance and improve power factor.
Examples of series reactors include air-core reactors, iron-core reactors, and...
Yes, core loss depends upon frequency.
Core loss is the energy lost in the magnetic core of a transformer or inductor.
It is caused by hysteresis and eddy current losses.
Hysteresis loss is proportional to the frequency and magnetic flux density.
Eddy current loss is proportional to the square of the frequency and the thickness of the core.
Higher frequency leads to higher core loss, which can cause overheating and reduced
I applied via Approached by Company and was interviewed before May 2022. There were 2 interview rounds.
The 3 tier breaker interlock scheme is used to ensure safe and efficient power distribution from different sources.
The scheme involves three levels of protection to prevent power overload and equipment damage.
The first tier involves interlocking the main breaker with the emergency stop button to quickly shut off power in case of an emergency.
The second tier involves interlocking the main breaker with the VFD and starte...

Current is the flow of electric charge in a circuit.
Current is measured in amperes (A).
It is caused by the movement of electrons or other charged particles.
Current can flow in both directions in an alternating current (AC) circuit.
In a direct current (DC) circuit, current flows in only one direction.
Current is essential for the operation of electrical devices and systems.
Examples of current include the flow of electric...

Transformers work on the principle of electromagnetic induction to transfer electrical energy between two or more circuits.
Transformers have two coils of wire, known as primary and secondary coils, which are wound around a core made of ferromagnetic material.
When an alternating current flows through the primary coil, it creates a changing magnetic field around the coil.
This changing magnetic field induces a voltage in ...
Transformers are cooled using methods such as oil cooling, air cooling, and water cooling.
Oil cooling: Transformers are immersed in oil to dissipate heat generated during operation.
Air cooling: Fans are used to circulate air around the transformer to cool it down.
Water cooling: Water is circulated around the transformer to absorb heat and cool it.
Forced oil cooling: Oil is circulated through a heat exchanger to remove
