There are two main types of stators: salient pole stators and non-salient pole stators.
Salient pole stators have protruding poles, which are commonly used in hydroelectric generators.
Non-salient pole stators have a smooth cylindrical shape and are typically used in gas and steam turbines.
Other types of stators include wound stators and squirrel cage stators.
A u dol diagram is a type of electrical diagram used to represent a three-phase transformer connection.
A u dol diagram consists of three sets of windings connected in a U shape, with the primary winding connected to the supply and the secondary winding connected to the load.
The diagram shows the connections of the primary and secondary windings, as well as the neutral point if applicable.
U dol diagrams are commonly use...
There are two main types of motors: AC motors and DC motors.
AC motors: Alternating current motors that are commonly used in household appliances and industrial applications.
DC motors: Direct current motors that are often used in small household devices, electric vehicles, and robotics.
Electricity is the flow of electric charge through a conductor.
Electricity is the flow of electrons through a conductor.
It is a form of energy that powers electrical devices.
Electricity can be generated from various sources such as coal, wind, solar, etc.
It is essential for modern society and is used in various applications like lighting, heating, and transportation.

The chance of survival depends on various factors such as insulation, grounding, and the strength of the electrical surge.
The chance of survival depends on the insulation of the car, as it acts as a barrier against electrical current.
If the car is properly grounded, it can help dissipate the electrical surge and reduce the risk of injury.
The strength of the electrical surge also plays a crucial role in determining the ...

I applied via Company Website and was interviewed in Jul 2021. There were 3 interview rounds.
EOt crane is an electric overhead traveling crane used for lifting and moving heavy loads in industrial settings.
EOt stands for Electric Overhead Traveling
It is operated by an electrical control system
It consists of a bridge, hoist, trolley, and electrical components
It is commonly used in factories, warehouses, and construction sites
It can lift and move heavy loads up to several tons
It requires regular maintenance and
I applied via Referral and was interviewed before May 2023. There were 3 interview rounds.
MCQ Question of total 10 question
Reverse arc flashing on ACB breaker refers to the phenomenon where the arc flash occurs on the opposite side of the contacts during the opening operation.
Reverse arc flashing happens when the arc flash occurs on the side of the contacts opposite to the normal direction during the opening operation of the ACB breaker.
This phenomenon can be caused by factors such as high fault currents, improper maintenance, or inadequat...
I appeared for an interview in Jan 2024.
Power factor is the ratio of real power to apparent power in an AC circuit. VFD stands for Variable Frequency Drive. AC motors run on alternating current while DC motors run on direct current.
Power factor is a measure of how effectively electrical power is being used in a circuit.
It is calculated by dividing the real power (in watts) by the apparent power (in volt-amperes).
A power factor of 1 indicates that all the pow...
Types of load cells include strain gauge load cells, hydraulic load cells, and capacitive load cells.
Strain gauge load cells measure the strain or deformation of a material.
Hydraulic load cells use hydraulic fluid to measure force.
Capacitive load cells measure changes in capacitance to determine force.
Other types of load cells include piezoelectric load cells and pneumatic load cells.
Composite error and ratio error are two types of errors in current transformers.
Composite error is the combination of ratio error and phase angle error in a current transformer.
Ratio error is the difference between the actual turns ratio and the specified turns ratio of a current transformer.
Phase angle error is the angular difference between the primary and secondary currents of a current transformer.
Composite error a...
An AC drive circuit diagram controls the speed of an AC motor by varying the frequency and voltage of the power supplied to it.
An AC drive consists of a rectifier, DC link, inverter, and control circuitry.
The rectifier converts AC power to DC power, which is stored in the DC link.
The inverter converts the DC power back to AC power with variable frequency and voltage.
The control circuitry adjusts the frequency and volta...
A single line diagram of a distribution system is required with proper specifications.
The diagram should show the flow of power from the source to the load
It should include all components such as transformers, switchgear, and cables
The specifications should include voltage levels, power ratings, and protection devices
The diagram should follow standard symbols and conventions
Example: A 11 kV distribution system with a 5
Dewpoint test is done in transformer to check the moisture content in the insulation oil.
Moisture in insulation oil can cause breakdown of transformer insulation
Dewpoint test helps to determine the moisture content in the oil
It is a preventive maintenance measure to avoid transformer failure
The test involves cooling a mirror until dew forms on it, and measuring the temperature at which dew forms
Power transformers are used in transmission systems to step up or down voltage, while distribution transformers are used in distribution systems to step down voltage.
Power transformers are used in high voltage transmission systems to step up or down voltage for long distance transmission.
Distribution transformers are used in low voltage distribution systems to step down voltage for local distribution.
Power transformers...
Buchholz relay is used to protect transformers from faults by detecting gas and oil flow abnormalities.
Buchholz relay is installed in the pipe connecting the transformer tank and conservator tank.
It operates based on the principle that faults in the transformer generate gases and cause oil flow disturbances.
When gas or oil flow abnormalities occur, the relay trips and sends a signal to the control panel to isolate the ...
