Travancore Titanium Products Instrumentation Technician Interview Questions and Answers

A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.

• Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.

• They consist of two coils of wire, known as the primary and secondary coils, which are wrapped around a magnetic core.

• When an AC voltage is applied to the primary coil, it creates a magne...read more

The type of breaker used depends on the electrical load and the circuit requirements.

• The most common types of breakers are standard, AFCI, GFCI, and dual-function.

• Standard breakers are used for general-purpose circuits.

• AFCI breakers are used for circuits that power bedrooms and living rooms.

• GFCI breakers are used for circuits that power bathrooms, kitchens, and outdoor areas.

• Dual-function breakers combine AFCI and GFCI...read more

Conductors are materials that allow electricity to flow through them. There are different types of conductors used in electrical systems.

• Copper is the most commonly used conductor in electrical wiring

• Aluminum is also used as a conductor, especially in high voltage power transmission

• Silver is the best conductor, but it is too expensive for most applications

• Gold is also a good conductor, but it is even more expensive tha...read more

MCB is a miniature circuit breaker while MCCB is a molded case circuit breaker.

• MCB is used for low current applications while MCCB is used for high current applications.

• MCB is rated up to 100 amps while MCCB can be rated up to 2500 amps.

• MCCB has adjustable trip settings while MCB does not.

• MCCB is more expensive than MCB.

• Examples of MCB brands include Legrand and Schneider while examples of MCCB brands include Siemens a

There are three types of alignment: shaft alignment, belt alignment, and gear alignment.

• Shaft alignment involves aligning the rotating shafts of machines to ensure smooth operation and prevent damage.

• Belt alignment refers to aligning the belts in machines such as conveyor systems to prevent slipping and maximize efficiency.

• Gear alignment involves aligning the gears in machines to ensure proper meshing and smooth transm

The number of gearbox motor and compressor alignments varies depending on the specific machinery and requirements.

• The number of gearbox motor and compressor alignments can range from one to multiple, depending on the number of machines and their configurations.

• Each gearbox motor and compressor alignment requires careful measurement and adjustment to ensure proper alignment and efficient operation.

• Examples of alignments...read more

A contractor is a person or company hired to perform a specific task or project for a client.

• Contractors are often hired for construction projects, electrical work, plumbing, and other specialized tasks.

• They are typically paid on a project-by-project basis, rather than receiving a salary or hourly wage.

• Contractors may work independently or as part of a larger company.

• They are responsible for providing their own tools, ...read more

A rectifier is an electrical device that converts alternating current (AC) to direct current (DC).

• Rectifiers are commonly used in power supplies for electronic devices.

• They can be made using diodes or other semiconductor devices.

• Rectifiers are essential for many electronic devices to function properly.

• Examples of rectifiers include bridge rectifiers, half-wave rectifiers, and full-wave rectifiers.

vvF is not a recognized term in the field of electrical engineering.

• vvF is not a standard unit of measurement or abbreviation in the electrical field.

• It is possible that the interviewer made a mistake or was testing the candidate's ability to admit when they don't know something.

• The candidate could respond by politely asking for clarification or admitting that they are not familiar with the term.
