Interview Questions and Answers

Different types of loads include resistive, inductive, and capacitive loads. Motor selection depends on factors like load type, power requirements, speed, and efficiency.

• Resistive loads convert electrical energy into heat, like incandescent light bulbs.

• Inductive loads create magnetic fields, like motors and transformers.

• Capacitive loads store electrical energy, like capacitors.

• Select motor based on load type, power requirements, speed, and efficiency.

• Consider factors like sta...read more

DGA test is a significant diagnostic tool used to analyze the dissolved gases in transformer oil to detect potential faults.

• DGA test helps in identifying potential faults in transformers by analyzing the presence of specific gases such as methane, ethylene, and acetylene.

• The levels of these gases can indicate issues like overheating, partial discharge, or arcing within the transformer.

• Interpretation of DGA results requires knowledge of typical gas ratios and trends associated...read more

Interlocks in the chiller are safety mechanisms that prevent the chiller from operating under unsafe conditions.

• Interlocks can include high pressure, low pressure, and temperature sensors that shut down the chiller if thresholds are exceeded.

• Interlocks may also include flow switches to ensure proper flow of refrigerant or water through the chiller.

• Some chillers have interlocks that prevent the compressor from starting if the oil level is too low.

• Interlocks are essential for p...read more

gd2 is a measure of the inertia of a rotating body, calculated as the product of the mass moment of inertia and the square of the angular velocity.

• gd2 is used in engineering to analyze the rotational motion of objects.

• It is calculated by multiplying the mass moment of inertia by the square of the angular velocity.

• gd2 is important in designing rotating machinery and systems.

• For example, in the design of a flywheel for energy storage, gd2 is a critical parameter.
