I applied via Referral and was interviewed in May 2024. There was 1 interview round.
The selection of a contactor depends on the load type, voltage, current, and duty cycle.
Consider the type of load (inductive, resistive, capacitive)
Calculate the voltage and current ratings of the load
Determine the duty cycle of the load (continuous, intermittent)
Select a contactor with appropriate voltage, current, and duty cycle ratings
Consider additional features like overload protection and coil voltage
Type 2 coordination chart is used in electrical engineering to show the coordination between protective devices.
Type 2 coordination chart shows the coordination between protective devices in an electrical system.
It helps in ensuring that the protective devices operate in the correct sequence during a fault.
The chart typically includes time-current curves for different protective devices.
It is important for preventing u...

Rotating parts of a machine are components that move in a circular motion, such as motors, turbines, or fans.
Rotating parts are typically components like motors, turbines, fans, or rotating shafts.
Non-rotating parts include components like housings, casings, brackets, or stationary supports.
Non-rotating parts are usually fixed in place and provide support or protection for the rotating components.
Examples of non-rotati...

A high starting torque machine is a type of motor that can produce a large amount of torque when starting up.
High starting torque machines are commonly used in applications where a large amount of torque is required at startup, such as in industrial machinery or electric vehicles.
These machines typically have special rotor designs or additional starting windings to provide the extra torque needed.
Examples of high start...

Home's law is a principle that states that the current flowing through a conductor is directly proportional to the voltage applied across it.
Home's law is also known as Ohm's law.
It is expressed as I = V/R, where I is the current, V is the voltage, and R is the resistance.
This law is fundamental to the study of electrical circuits and is used to calculate the behavior of circuits.
For example, if the voltage across a re...
The current unit is the ampere (A), which measures the flow of electric charge.
The unit of electric current is the ampere (A).
Current is the rate of flow of electric charge.
It is measured using an ammeter.
One ampere is equal to one coulomb of charge passing through a point in one second.
Voltage is the unit of measurement for electric potential difference.
Voltage is the force that pushes electric charges through a circuit.
It is measured in volts (V).
Voltage is essential for the operation of electrical devices.
Examples of voltage units include millivolts (mV), kilovolts (kV), and megavolts (MV).
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it.
Ohm's law is expressed as V = I * R, where V is the voltage, I is the current, and R is the resistance.
The current symbol is represented by the letter 'I'.
Ohm's law is fundamental in understanding and analyzing electrical circuits.
Example: If a circuit has a voltage of 12 volts and a resistance of 4 o...
The two types of winding in electrical engineering are lap winding and wave winding.
Lap winding is used in DC machines and is characterized by multiple parallel paths for current flow.
Wave winding is used in AC machines and is characterized by a single path for current flow.
Lap winding provides high current capacity and low voltage output, while wave winding provides low current capacity and high voltage output.
In lap ...
The primary winding is the first coil in a transformer that receives electrical energy.
The primary winding is typically connected to the power source.
It is responsible for receiving and transmitting electrical energy to the secondary winding.
The number of turns in the primary winding determines the voltage ratio between the primary and secondary sides.
Primary windings are commonly found in transformers, induction motor
