10+ IKA Interview Questions and Answers

Diesel consumption in the DG is tracked using fuel monitoring systems and regular manual readings.

• Fuel monitoring systems are installed in the DG to track diesel consumption.

• These systems measure the amount of fuel used and provide real-time data.

• Manual readings are also taken regularly to cross-verify the data from the monitoring systems.

• The readings are recorded and compared to previous readings to calculate the consumption.

• Any discrepancies or issues with the fuel consumpt...read more

Possible reasons for a DG not starting

• Fuel supply issue

• Battery failure

• Faulty ignition system

• Overheating

• Blocked air intake

• Electrical wiring problem

Earthing is the process of connecting electrical equipment to the earth to prevent electric shock. Neutral is a conductor that carries current back to the source.

• Earthing prevents electric shock by providing a path for current to flow to the ground

• Neutral is a conductor that has zero voltage and carries current back to the source

• Earthing and neutral are important for electrical safety and proper functioning of electrical equipment

DG safeties are safety measures implemented in field support engineering to ensure the safe operation of diesel generators.

• DG safeties refer to safety features and protocols designed to prevent accidents and ensure the proper functioning of diesel generators.

• These safeties may include measures such as automatic shutdown systems, emergency stop buttons, and alarms.

• They are put in place to protect both the equipment and the personnel working with or around the diesel generators...read more

A generator works by converting mechanical energy into electrical energy.

• A generator consists of a rotor and a stator.

• The rotor rotates inside the stator, creating a magnetic field.

• This magnetic field induces an electrical current in the stator windings.

• The electrical current is then transferred out of the generator and into a power grid or battery.

• Generators can be powered by various sources such as fossil fuels, wind, or water.

• The size and capacity of a generator can vary d...read more

The efficiency of solar panels refers to the amount of sunlight that is converted into usable electricity.

• Efficiency of solar panels is typically around 15-22%, with some high-end panels reaching up to 25%

• Factors affecting efficiency include location, angle of installation, shading, and temperature

• Regular maintenance and cleaning can help improve efficiency over time

Converters and inverters are electronic devices used to convert electrical energy from one form to another.

• Converters are used to convert AC to DC or vice versa

• Inverters are used to convert DC to AC

• Converters are commonly used in power supplies, battery chargers, and motor drives

• Inverters are commonly used in solar power systems, electric vehicles, and uninterruptible power supplies

The power rating of a tubelight determines the amount of electricity it consumes and the brightness it produces.

• The power rating of a tubelight is typically measured in watts (W).

• Higher power ratings indicate brighter light output but also higher energy consumption.

• For example, a tubelight with a power rating of 18W will be brighter than one with a rating of 10W.

• It is important to consider the power rating when choosing a tubelight to ensure it meets your lighting needs effic...read more

SMPS stands for Switched Mode Power Supply. It is a type of power supply that uses switching devices to convert electrical power efficiently.

• SMPS converts AC voltage to DC voltage through a switching regulator

• It is more efficient than linear power supplies as it reduces power loss

• SMPS can be found in various electronic devices like computers, TVs, and mobile chargers

A diesel engine is an internal combustion engine that uses compression ignition to burn fuel, typically diesel fuel.

• Diesel engines do not require spark plugs for ignition

• They are more fuel efficient than gasoline engines

• Commonly used in trucks, buses, and heavy machinery

A battery bank is a collection of batteries used to store electrical energy for later use.

• Battery banks are commonly used in off-grid solar systems to store energy for use when the sun is not shining.

• They can also be used in backup power systems to provide electricity during power outages.

• Battery banks can be made up of various types of batteries, such as lead-acid, lithium-ion, or nickel-cadmium.

• Proper maintenance and monitoring of a battery bank is essential to ensure optim...read more
