I applied via Recruitment Consultant and was interviewed in Dec 2021. There were 3 interview rounds.
Vector group of transformers is used to determine the phase difference and voltage ratio between primary and secondary windings.
Vector group helps in determining the correct connection of transformers in parallel.
It helps in identifying the phase angle difference between primary and secondary windings.
It helps in determining the voltage ratio between primary and secondary windings.
Vector group is important for power sy...
IR value is a measure of insulation resistance in transformers and motors.
IR value indicates the condition of insulation in transformers and motors.
It is measured in megaohms (MΩ) using a megger.
A high IR value indicates good insulation while a low value indicates poor insulation.
Regular testing of IR value is important to prevent breakdowns and ensure safety.
For example, a transformer with an IR value of less than 1 M...
Switchgear selection for a 75 kW motor depends on various factors such as voltage, current, starting method, and protection requirements.
Consider the voltage and current rating of the motor
Choose the appropriate starting method such as DOL, star-delta, soft starter, or VFD
Select the switchgear with suitable protection features such as overload, short circuit, and earth fault protection
Ensure compatibility with the exis...

I applied via Company Website and was interviewed in Mar 2022. There were 2 interview rounds.
The question covers slope percentage calculation of kiln, tan value in oil analysis, and material and manpower handling.
For slope percentage calculation of kiln, we need to measure the height and length of the kiln and use the formula tan(theta) = height/length.
Tan value in oil analysis is used to determine the acidity of the oil. It is calculated by dividing the acid number by the saponification number.
Material and ma...

Testing of motors involves various methods to ensure functionality and performance.
Performing insulation resistance tests to check for any electrical faults
Conducting load tests to measure the motor's performance under different conditions
Checking for abnormal noise or vibrations during operation
Inspecting the motor for any physical damage or wear
Using thermography to detect overheating issues
Transformer safety relays are devices used to protect transformers from faults and overloads.
Transformer safety relays monitor the electrical parameters of a transformer, such as current, voltage, and temperature.
They can trip the transformer offline in case of a fault to prevent damage.
Some common types of transformer safety relays include overcurrent relays, differential relays, and temperature relays.
