Aviator Infotech Interview Questions, Process, and Tips

UPS provides backup power to prevent data loss and equipment damage during power outages.

• Prevents data loss and equipment damage during power outages

• Provides backup power to critical systems

• Ensures uninterrupted power supply

• Protects against power surges and spikes

• Ideal for businesses with mission-critical operations

Load can be calculated by determining the amount of power consumed by a device or system.

• Calculate the power consumption of the device or system

• Determine the voltage and current of the load

• Use the formula P = VI to calculate the load

• Consider the power factor of the load

• Use a wattmeter or multimeter to measure the load

The question is unclear. Please provide more context.

• Please provide more information about what you are asking.

• Are you asking about the current state of a particular industry or market?

• Are you asking about the current flow of electricity?

• Please clarify your question so I can provide a more accurate answer.

Power can be calculated by multiplying voltage and current.

• Power (P) = Voltage (V) x Current (I)

• Unit of power is watt (W)

• Power can also be calculated by dividing work done by time taken

• P = W/t

Loss in electrical refers to the amount of energy lost during transmission and distribution of electricity.

• Loss in electrical systems can occur due to resistance in wires and transformers.

• This loss is commonly referred to as 'line loss' or 'transmission loss'.

• It is typically measured as a percentage of the total energy transmitted.

• Efforts are made to minimize loss through the use of efficient equipment and better trans...read more

UPS block diagram is a graphical representation of the components and their connections in an uninterruptible power supply system.

• UPS block diagram consists of input power source, rectifier, battery, inverter, and output load.

• The input power source is connected to the rectifier which converts AC power to DC power.

• The battery is connected to the DC bus and provides backup power in case of power failure.

• The inverter conv...read more

SLD stands for Single Line Diagram. It is a graphical representation of an electrical system.

• SLD shows the flow of electrical power in a system

• It includes all the components of the system like transformers, generators, breakers, etc.

• SLD helps in identifying faults and troubleshooting

• It is designed using standard symbols and conventions

• SLD is used in power system planning, design, and maintenance

Power generation involves converting energy sources into electricity, which is then distributed through a network of power lines.

• Power generation can come from various sources such as coal, natural gas, nuclear, hydro, wind, and solar.

• The electricity generated is then transmitted through high-voltage power lines to substations.

• At the substations, the voltage is reduced and the electricity is distributed to homes and bu...read more

Resistance is the opposition to the flow of electric current, while impedance is the total opposition to the flow of alternating current.

• Resistance is measured in ohms and is caused by the physical properties of a material.

• Impedance is measured in ohms as well, but it takes into account both resistance and reactance.

• Reactance is the opposition to the flow of alternating current caused by capacitance or inductance.

• Imped...read more

The colour code of resistance is a system used to identify the resistance value of electronic components.

• The code consists of four or five coloured bands on the component.

• The first two bands represent the significant digits of the resistance value.

• The third band represents the multiplier or number of zeros to be added to the significant digits.

• The fourth band represents the tolerance or the percentage deviation from th...read more

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

• Ohm's law is a fundamental law of electrical engineering.

• It relates the three basic electrical quantities: voltage, current, and resistance.

• The formula for Ohm's law is V = IR, where V is voltage, I is current, and R is resistance.

• Ohm's law is used to calculate the behavior of electric ...read more
