10+ Plasser India Interview Questions and Answers

OLR setting in a star-delta connection determines the transition point between star and delta mode.

• OLR stands for Overload Relay.

• In a star-delta connection, the motor is initially started in star mode to reduce the starting current.

• After a certain time, the motor is switched to delta mode for normal operation.

• The OLR setting determines the current threshold at which the transition from star to delta occurs.

• The OLR setting should be adjusted based on the motor's rated current ...read more

The two earthing terminals in a motor provide redundancy and ensure safety in case of a fault.

• The first earthing terminal is connected to the motor frame, providing a path for fault current to flow and preventing electric shock to personnel.

• The second earthing terminal is connected to the motor winding, providing a path for fault current to flow and protecting the motor from damage.

• Having two earthing terminals ensures redundancy, so that even if one connection fails, the oth...read more

Yes, I can read drawings.

• I have experience reading technical drawings and blueprints.

• I am familiar with symbols, dimensions, and tolerances used in drawings.

• I can interpret different views and sections in a drawing.

• I understand the importance of accuracy and attention to detail when reading drawings.

• I have successfully operated VMC machines based on drawings provided.

SCCR stands for Short-Circuit Current Rating.

• SCCR is a measure of the maximum amount of current that a device or system can safely withstand during a short circuit.

• It is an important consideration in electrical design to ensure the protection of equipment and personnel.

• SCCR is typically expressed in amperes (A) and is determined through testing or calculations.

• It helps in selecting appropriate protective devices such as fuses, circuit breakers, or disconnect switches.

• For exam...read more

HRC fuse stands for High Rupturing Capacity fuse. It is a type of fuse that is designed to safely interrupt high fault currents.

• HRC fuse is used in electrical systems to protect against overcurrents and short circuits.

• It has a high breaking capacity, which means it can safely interrupt high fault currents without causing damage.

• The fuse contains a fuse element made of a material that can withstand high temperatures and currents.

• When a fault occurs, the fuse element melts and ...read more

5S is a workplace organization method that stands for Sort, Set in Order, Shine, Standardize, and Sustain.

• Sort: Remove unnecessary items from the workplace

• Set in Order: Organize the remaining items in a logical and efficient manner

• Shine: Clean and maintain the workplace regularly

• Standardize: Establish procedures and guidelines for maintaining the workplace

• Sustain: Continuously improve and maintain the 5S system

Controlling quality through 8D and other QC tools involves a systematic approach to problem-solving and continuous improvement.

• 8D (Eight Disciplines) is a problem-solving methodology used to identify, correct, and prevent recurring problems.

• Other QC tools such as Pareto charts, fishbone diagrams, control charts, and statistical process control (SPC) help in analyzing data and identifying root causes of quality issues.

• The 8D process includes steps like forming a team, describi...read more

NO

• I don't have the available data to make a WIS right now

• I am unable to provide a descriptive answer without the necessary information

Transfer efficiency is the measure of how effectively energy or material is transferred from one system or process to another.

• Transfer efficiency is a ratio that compares the amount of energy or material input to the amount of useful output.

• It is commonly used in engineering to evaluate the effectiveness of processes or systems.

• Transfer efficiency can be calculated by dividing the useful output by the total input and multiplying by 100%.

• For example, in a heat exchanger, trans...read more

Heat resistant refers to the ability of a material or substance to withstand high temperatures without being damaged or altered.

• Heat resistant materials can maintain their structural integrity and functionality even when exposed to extreme heat.

• These materials have high melting points and low thermal conductivity.

• Examples of heat resistant materials include ceramics, refractory metals, and certain polymers.

• Heat resistant coatings and paints are also used to protect surfaces f...read more

The project management lifecycle can be implemented by following a structured approach that includes planning, execution, monitoring, and closure.

• Define project scope and objectives

• Develop a project plan with timelines and milestones

• Assign tasks and responsibilities to team members

• Monitor progress and make adjustments as needed

• Close out the project and evaluate its success

• Use tools such as Gantt charts and project management software

• Communicate regularly with stakeholders
