Blocked rotor test is performed on a 3-phase induction motor to determine its impedance and calculate its locked rotor current.
The motor is connected to a 3-phase supply with the rotor blocked.
The voltage and current are measured and used to calculate the motor's impedance.
The locked rotor current can be determined from the impedance.
The test helps in assessing the motor's performance and identifying any faults or issu
Single phase induction motor is not self-starting due to the absence of rotating magnetic field. Different methods of starting include capacitor start, split-phase, shaded pole, and reluctance start.
Single phase induction motor lacks rotating magnetic field
Capacitor start uses a capacitor to create a phase shift and start the motor
Split-phase uses a starting winding to create a phase shift
Shaded pole uses a shading coi...
Different methods of resistance measurement and their ranges
Low resistance measurement: 4-wire Kelvin method, range 0.1 μΩ to 1 Ω
Medium resistance measurement: 2-wire method, range 1 Ω to 1 MΩ
High resistance measurement: Megohmmeter method, range 1 MΩ to 10 TΩ
Other methods include 3-wire method and 4-wire guarded method
Measurement accuracy depends on the method used and the quality of the equipment
Lightning arresters are used in transmission lines to protect the equipment and infrastructure from damage caused by lightning strikes.
Lightning arresters divert the high voltage surge caused by lightning strikes to the ground, preventing it from damaging the transmission lines.
They provide a low-resistance path for the lightning current to flow, reducing the risk of electrical breakdown and flashovers.
Lightning arrest...

To design busbar for increased fault level but same current rating, increase the cross-sectional area of the busbar.
Increase the thickness of the busbar
Increase the width of the busbar
Use materials with higher conductivity
Use busbar supports with higher short-circuit strength
Consider the temperature rise of the busbar
Perform a fault level calculation to determine the required cross-sectional area
The bending radius for HT cables varies depending on the cable type and size.
The bending radius for XLPE cables is typically 12 times the cable diameter.
For PILC cables, the bending radius is usually 20 times the cable diameter.
The bending radius for EPR cables is generally 10 times the cable diameter.
It is important to follow the manufacturer's recommendations for bending radius to avoid damaging the cable.

Concrete is the most important as it provides the strength and durability to the structure.
Concrete is the backbone of any RCC structure.
It provides the strength and durability to the structure.
Reinforcements and formwork are important too, but without concrete, they are useless.
Proper mix design and curing of concrete are crucial for the longevity of the structure.
I applied via Company Website and was interviewed before Apr 2020. There were 4 interview rounds.
Mix design of concrete and BTech project
Mix design involves determining the proportions of cement, water, aggregates, and admixtures to achieve desired properties of concrete
Factors like strength, workability, durability, and cost are considered while designing the mix
BTech project can involve studying the effect of different mix designs on properties of concrete or developing a new mix design
Examples of BTech projects...
