10+ Practova Technologies 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.

• Vaccine is a preventive measure that helps the body develop immunity against a particular disease.

• Injection is a method of delivering substances such as vaccines, medications, or fluids into the body.

• Vaccines can contain weakened or killed forms of the disease-causing organism, while injections can deliver v...read more

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

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
