An induction motor works by using electromagnetic induction to generate a rotating magnetic field.
An induction motor consists of a stator and a rotor.
The stator has a set of windings that are connected to an AC power source.
When the AC power is applied, it creates a rotating magnetic field in the stator.
The rotating magnetic field induces currents in the rotor windings, which in turn creates a magnetic field in the rot...

Answering generator sizing calculations for Electrical Engineer interview.
Generator sizing calculations involve determining the power requirements of the load to be supplied by the generator.
Factors to consider include the type of load, the starting current, and the power factor.
The generator should be sized to handle the maximum expected load, with some margin for safety.
Generator sizing calculations can be done manua...
Load list is a document that lists all the electrical loads in a building or facility.
It includes details such as the name of the load, its location, power rating, and voltage requirements.
Load list is used to determine the total power demand of the building and to design the electrical system accordingly.
It is also used for maintenance and troubleshooting purposes.
Examples of loads that may be included in a load list ...
Differential relays are typically located at the ends of a protected zone.
Differential relays are used to detect faults within a protected zone
They compare the current entering and leaving the zone
If there is a difference, it indicates a fault
The relay is typically located at the end of the zone closest to the source
This allows for the quickest detection and isolation of faults

CT sizing is done by considering the primary current, burden, and accuracy class of the CT.
Determine the primary current of the system
Calculate the burden of the CT
Select the accuracy class of the CT
Use the formula: CT rating = primary current x burden / (accuracy class x 100)
Example: For a 400A primary current, 5VA burden, and 0.5 accuracy class, CT rating = 400 x 5 / (0.5 x 100) = 40A
