Wayzon Technology Services Interview Questions and Answers
Q1. How to find transformer primary side
The primary side of a transformer can be found by checking the voltage rating on the nameplate.
Check the nameplate for voltage rating
The higher voltage rating is usually the primary side
Use a multimeter to confirm the primary side
Q2. Volume of 12 mtr height & 350 mm dia pile concrete
Calculate the volume of concrete in a pile with a height of 12 meters and a diameter of 350 mm.
Calculate the radius of the pile by dividing the diameter by 2 (175 mm)
Calculate the volume of the pile using the formula V = πr^2h
Convert the diameter and height to meters for consistent units
Substitute the values into the formula to find the volume of concrete in the pile
Q3. Current carrying capacity of Rabbit conductor ?
The current carrying capacity of Rabbit conductor depends on various factors such as material, size, and temperature.
Current carrying capacity is influenced by the material of the conductor (e.g. copper, aluminum).
The size of the conductor (gauge or diameter) also plays a role in determining its current carrying capacity.
Temperature affects the current carrying capacity of a conductor, with higher temperatures reducing the capacity.
For Rabbit conductor, the current carrying c...read more
Q4. Why we use GI material ?
GI material is used for its corrosion resistance and durability in electrical engineering applications.
GI material (Galvanized Iron) is coated with a layer of zinc to protect against corrosion, making it ideal for outdoor applications.
It has high durability and can withstand harsh environmental conditions, making it suitable for long-term use.
GI material is cost-effective compared to other corrosion-resistant materials like stainless steel.
It is easy to work with and can be w...read more
Q5. Explain generation & transmission, distribution
Generation is the process of producing electricity, transmission is the movement of electricity over long distances, and distribution is the delivery of electricity to consumers.
Generation involves converting energy sources such as coal, natural gas, or wind into electricity.
Transmission involves high voltage power lines that transport electricity over long distances from power plants to substations.
Distribution involves lower voltage power lines that deliver electricity from...read more
Q6. What is corona effect
Corona effect is the phenomenon of ionization and luminous discharge around a conductor carrying high voltage in air.
Occurs when the electric field strength around a conductor exceeds the breakdown strength of air
Results in ionization of air molecules and formation of a luminous discharge or corona
Can cause power loss, radio interference, and damage to equipment
Examples include the hissing sound from high voltage power lines and the glow around lightning rods
Q7. Mixing ratio of concrete
Mixing ratio of concrete refers to the proportion of cement, sand, and aggregate used in the concrete mix.
The most common mixing ratio for concrete is 1:2:4, which means 1 part cement, 2 parts sand, and 4 parts aggregate.
Other ratios like 1:1.5:3 and 1:3:6 are also used depending on the strength and durability requirements of the concrete.
Water is added to the mix to achieve the desired consistency and workability.
Proper mixing of the ingredients is crucial to ensure the stre...read more
Q8. Ratting of MCB ?
MCB stands for Miniature Circuit Breaker. It is a device designed to protect electrical circuits from overloads and short circuits.
MCB ratings are typically in multiples of 6, such as 6A, 10A, 16A, 20A, etc.
The rating of an MCB should be selected based on the maximum current that the circuit can safely handle.
For example, a lighting circuit may use a 6A MCB, while a power socket circuit may use a 16A MCB.
MCBs have a breaking capacity, which indicates the maximum fault current...read more
Q9. Types of perlin
Perlin noise is a type of gradient noise used in computer graphics for creating natural-looking textures and animations.
Perlin noise is a type of coherent noise, meaning it smoothly transitions from one value to another without sudden jumps.
It is commonly used in procedural generation for creating realistic terrain, clouds, and other natural phenomena.
There are different variations of Perlin noise, such as simplex noise and improved Perlin noise, which aim to reduce computati...read more
