I applied via Walk-in and was interviewed in Mar 2023. There were 2 interview rounds.
VFD programming refers to the process of configuring and controlling Variable Frequency Drives.
VFD programming involves setting parameters such as motor speed, acceleration, and deceleration
It allows for precise control of motor speed and torque
Programming can be done through a computer interface or keypad on the VFD
Examples of VFD programming languages include ladder logic and function block programming
A 3-phase motor circuit diagram consists of three sets of windings, each connected to a different phase of the power supply.
Draw three sets of windings, each with a different color to represent the three phases
Connect the windings to the power supply, with each winding connected to a different phase
Include a symbol for the motor, such as a circle with the letters 'M' inside
Label the windings with the appropriate letter...

Star delta starter is a type of reduced voltage starter used for starting high power motors.
Consists of two contactors - one for star connection and one for delta connection
Reduces starting current and torque to prevent damage to motor windings
Commonly used for motors with high starting current requirements, such as induction motors
Hysteresis loss can be calculated using the area enclosed by the hysteresis loop on a B-H curve.
Calculate the area enclosed by the hysteresis loop on a B-H curve
Use the formula: Hysteresis Loss = ∮B.dH
Consider the material's properties and operating conditions for accurate calculation
Skin effect is the tendency of alternating current to flow near the surface of a conductor, due to self-inductance.
Skin effect is more prominent at higher frequencies.
It causes the effective resistance of the conductor to increase.
Skin effect can be reduced by using hollow conductors or by using stranded conductors.
Example: Skin effect is a common phenomenon in high-frequency transmission lines.
Fluorescent effect is the emission of light by a substance that has absorbed light or other electromagnetic radiation.
Fluorescent effect occurs when a substance absorbs light at a specific wavelength and then re-emits light at a longer wavelength.
Common examples include fluorescent light bulbs, glow-in-the-dark materials, and certain minerals that glow under UV light.
Fluorescent materials can be used in various applica...
In a parallel circuit, components are connected in separate branches, allowing current to flow through multiple paths. In a series circuit, components are connected in a single path, where current flows through each component in sequence.
Parallel circuit allows current to flow through multiple paths, while series circuit has only one path for current.
In a parallel circuit, voltage across each component is the same, whi...

SMPS is a power supply that uses high-frequency switching to convert AC voltage to DC voltage.
SMPS is more efficient than traditional linear power supplies
It uses a switching regulator to control the output voltage
SMPS can be found in computers, TVs, and other electronic devices
It can be designed to work with different input voltages and frequencies
HMI is the interface between a human operator and a machine that allows for control and monitoring of the machine's functions.
HMI is used in various industries such as manufacturing, transportation, and energy
It includes components such as touchscreens, buttons, and indicators
HMI can display real-time data and provide alerts for potential issues
Examples of HMI include the dashboard in a car and the control panel in a f
MTBF is Mean Time Between Failures and MTTR is Mean Time To Repair.
MTBF is the average time between two consecutive failures of a system or component.
MTTR is the average time taken to repair a failed system or component.
MTBF and MTTR are important metrics in maintenance engineering to measure system reliability and availability.
MTBF can be calculated by dividing the total operating time by the number of failures.
MTTR c...
There are generally 4 types of maintenance: corrective, preventive, predictive, and condition-based.
Corrective maintenance involves fixing a problem after it has occurred.
Preventive maintenance involves scheduled maintenance to prevent problems from occurring.
Predictive maintenance involves using data and analytics to predict when maintenance is needed.
Condition-based maintenance involves monitoring equipment and perfo...
