The timer in the Satar Delta Satar controls the switching between star and delta configurations in a motor.
The timer is responsible for automatically switching the motor from star to delta configuration after a set time period.
This helps in reducing the starting current and providing a smoother transition for the motor.
For example, in a motor starting application, the timer ensures that the motor starts in star configu...
A star-delta starter is used to reduce the starting current of induction motors.
Reduces the starting current by initially connecting the motor in star configuration and then switching to delta configuration
Helps in reducing voltage drops during motor starting
Used for large induction motors to prevent damage to the motor windings
Commonly used in industries where high-power motors are employed
The equivalent wattage of 1 horsepower is 746 watts.
1 horsepower is equal to 746 watts.
This conversion is commonly used in electrical engineering and mechanical fields.
For example, if a motor has a power rating of 2 horsepower, it would be equivalent to 1492 watts.
Active power is the actual power consumed by a circuit, while reactive power is the power that flows back and forth between the circuit and the source without being consumed.
Active power is measured in watts (W) and represents the real power used to perform work in a circuit.
Reactive power is measured in volt-amperes reactive (VAR) and represents the power oscillating between the circuit and the source due to inductive...
kW is the actual power consumed by a device, while kVA is the apparent power used by the device including reactive power.
kW measures the actual power consumed by a device, taking into account only real power
kVA measures the total power used by a device, including both real power (kW) and reactive power (kVAR)
The relationship between kW and kVA is influenced by the power factor of the device
For example, a device with a ...
A kvar is a unit of reactive power in an electrical system, measured in kilovolt-amperes.
Kvar is used to measure the reactive power in an electrical system, which is the power consumed by inductive loads such as motors and transformers.
It is important to manage kvar to ensure efficient power factor correction and reduce energy losses in the system.
Kvar is calculated using the formula: kvar = kVA * sin(theta), where the...
The purpose of using and maintaining power factor is to improve energy efficiency, reduce electricity costs, and prevent equipment damage.
Improves energy efficiency by reducing wasted energy in the system
Reduces electricity costs by optimizing power usage
Prevents equipment damage by ensuring proper voltage and current levels
Helps in meeting utility requirements and avoiding penalties for low power factor
Examples: Insta...

I applied via Campus Placement and was interviewed in Apr 2024. There was 1 interview round.
Ohm's Law states that current is equal to voltage divided by resistance.
Ohm's Law is a fundamental principle in electrical engineering
Current (I) is measured in Amperes (A)
Voltage (V) is measured in Volts (V)
Resistance (R) is measured in Ohms (Ω)
The formula I = V/R can be used to calculate current in a circuit
Ohm's law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points.
Ohm's law is represented by the equation V = IR, where V is voltage, I is current, and R is resistance.
It is named after German physicist Georg Simon Ohm.
Ohm's law is fundamental in the field of electrical engineering and is used to analyze and design electrical circuits.

Weber (Wb)
The SI unit of flux is Weber (Wb)
Flux is a measure of the flow of a physical quantity through a surface
It is commonly used in electromagnetism and is defined as the amount of magnetic field passing through a surface
AC stands for alternating current, which changes direction periodically, while DC stands for direct current, which flows in one direction.
AC changes direction periodically, while DC flows in one direction constantly.
AC is used in household appliances and power distribution, while DC is used in batteries and electronic devices.
AC can be easily converted to different voltage levels using transformers, while DC requires m...
Current carrying in a conductor can be calculated using Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R).
Use Ohm's Law: I = V / R
Determine the voltage across the conductor
Find the resistance of the conductor
Calculate the current flowing through the conductor using the formula

Python is a high-level programming language with dynamic semantics. It has various built-in data types.
Python has six built-in data types: integers, floating-point numbers, complex numbers, strings, booleans, and None.
Python is dynamically typed, which means that you don't need to declare the data type of a variable before using it.
Python also supports various data structures like lists, tuples, sets, and dictionaries.
...
Function is a block of code that performs a specific task. List and tuple are both data structures in Python, but list is mutable while tuple is immutable.
Functions are reusable blocks of code that can be called multiple times
Lists are mutable and can be modified after creation
Tuples are immutable and cannot be modified after creation
Lists are defined using square brackets [] while tuples use parentheses ()
Lists are ty...
Type D.G pandals are diesel generator sets used for backup power supply.
D.G pandals are commonly used in industries, hospitals, and events.
They provide backup power supply in case of power outages.
The 'D.G' stands for 'diesel generator'.
Regular maintenance and testing is required to ensure their proper functioning.
Examples of type D.G pandals include Cummins, Kirloskar, and Mahindra generators.
