Schneider Electric Interview Questions, Process, and Tips for Freshers

Basic logical reasoning questions were asked, with a greater emphasis on quantitative aptitude.

Q1. Design an Astable Multivibrator and explain its functioning
Ans. 
An Astable Multivibrator is a type of oscillator circuit that generates a continuous square wave output.
• Consists of two transistors cross-coupled through capacitors and resistors

• No stable state, continuously switches between high and low states

• Capacitors charge and discharge alternately, creating oscillations

• Commonly used in applications like signal generators, LED flashers, and tone generators

Q2. Draw the VI characteristics of a pn junction diode and explain the graph
Ans. 
The VI characteristics of a pn junction diode show the relationship between voltage and current flowing through the diode.
• The graph shows a non-linear relationship between voltage and current, with forward and reverse bias regions.

• In forward bias, the diode conducts current easily with a small voltage drop, while in reverse bias, it blocks current flow until breakdown voltage is reached.

• The knee voltage in the forward ...read more

Q2. What type of conductor use in transmission line
Ans. 
Copper and aluminum conductors are commonly used in transmission lines.
• Copper conductors have high conductivity and are often used in high voltage transmission lines.

• Aluminum conductors are lighter and cheaper, making them suitable for long distance transmission lines.

• Composite conductors, such as Aluminum Conductor Steel Reinforced (ACSR), are also used for their strength and conductivity.

Q1. Brushless motor advantage
Ans. 
Brushless motors offer higher efficiency, longer lifespan, and better control compared to brushed motors.
• Higher efficiency due to lack of brushes reducing friction and heat generation

• Longer lifespan as there are no brushes to wear out

• Better control and precision in speed and torque

• Examples: drones, electric vehicles, industrial machinery
