10+ LEONIA Interview Questions and Answers

DG set works on the principle of converting mechanical energy into electrical energy using a diesel engine.

• DG set stands for Diesel Generator set.

• Diesel engine burns diesel fuel to produce mechanical energy.

• The mechanical energy is then converted into electrical energy by the alternator.

• The alternator consists of a rotor and a stator which generate electricity through electromagnetic induction.

Types of transformers include step-up, step-down, isolation, autotransformer, and distribution transformers.

• Step-up transformer increases voltage output

• Step-down transformer decreases voltage output

• Isolation transformer provides electrical isolation between primary and secondary windings

• Autotransformer has a single winding with multiple taps for different voltage levels

• Distribution transformer supplies power to residential and commercial areas

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Transformers are used to increase or decrease voltage levels in electrical circuits.

• They consist of two coils of wire, known as the primary and secondary coils.

• The primary coil is connected to the input voltage source, while the secondary coil is connected to the output load.

• Transformers are commonly used in power distribution systems to step u...read more

A DOL starter is a direct online starter used to start and stop the motor by connecting it directly to the power supply.

• DOL stands for Direct Online starter.

• It is the simplest and most economical method to start an induction motor.

• It directly connects the motor to the power supply without any soft starting or speed control.

• It consists of a contactor, overload relay, and start and stop push buttons.

• Used for small to medium-sized motors where speed control is not required.

The full load current of a 3 hp motor depends on the motor efficiency and voltage rating.

• Full load current can be calculated using the formula: Full Load Current = (HP x 746) / (Efficiency x Voltage x 1.73)

• For a 3 hp motor with 90% efficiency and 230V voltage rating, the full load current would be approximately 12.3 Amps

• It is important to consider the motor's efficiency and voltage rating when calculating full load current

Sterility refers to the absence of viable microorganisms, and sterilization is the process of eliminating all forms of life from a surface, object, or substance.

• Sterility is the state of being free from living microorganisms.

• Sterilization is the process of killing or removing all forms of life, including bacteria, viruses, fungi, and spores.

• There are different types of sterilization methods, including heat sterilization, chemical sterilization, radiation sterilization, and fi...read more

HP stands for horsepower, a unit of measurement for power in the electrical field.

• HP is a unit of measurement for power in the electrical field

• 1 HP is equal to 746 watts

• HP is commonly used to rate the power output of electric motors

Pre-call planning to a chemist involves researching the chemist's background, understanding their needs, and preparing relevant information and materials.

• Research the chemist's background, including their education, experience, and areas of expertise.

• Identify the chemist's needs and pain points, such as specific challenges they may be facing in their work.

• Prepare relevant information and materials, such as product brochures, scientific studies, or samples, that address the ch...read more

MCCB stands for Molded Case Circuit Breaker, a type of electrical protection device.

• MCCB is a type of circuit breaker that is commonly used in electrical distribution systems.

• It provides protection against overcurrent and short circuit faults.

• MCCBs have adjustable trip settings for different levels of current protection.

• They are often used in industrial and commercial applications.

• Examples of MCCB manufacturers include Schneider Electric, Siemens, and ABB.

The female reproductive parts include the ovaries, fallopian tubes, uterus, cervix, and vagina.

• Ovaries produce eggs and hormones like estrogen and progesterone

• Fallopian tubes transport eggs from the ovaries to the uterus

• Uterus is where a fertilized egg implants and develops into a fetus

• Cervix is the lower part of the uterus that connects to the vagina

• Vagina is the birth canal and also where menstrual blood exits the body

Immunity is the ability of an organism to resist infections and diseases. There are two types of immunity: innate and adaptive.

• Innate immunity is the natural defense mechanism of the body that is present at birth. It includes physical barriers like skin and mucous membranes, as well as non-specific immune cells like neutrophils and macrophages.

• Adaptive immunity is acquired over time through exposure to pathogens or through vaccination. It involves the production of specific a...read more
