A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
Transformers are used to increase or decrease voltage levels in electrical circuits.
They consist of two coils of wire, known as the primary and secondary coils, wrapped around a core made of iron or other magnetic materials.
Step-up transformers increase voltage levels, while step-down tr...
DG set stands for Diesel Generator set. It is a combination of a diesel engine and an electric generator used to generate electricity.
DG set is commonly used as a backup power source in case of power outages.
It is often used in places where there is no access to the main power grid.
DG sets come in various sizes and capacities to suit different power requirements.
They are typically used in industries, commercial buildin...
UPS stands for Uninterruptible Power Supply, used to provide backup power during electrical outages or fluctuations.
UPS helps prevent data loss and damage to electronic devices during power outages.
It also provides protection against power surges and spikes.
UPS units come in various sizes and capacities to suit different needs, from small home offices to large data centers.
I appeared for an interview in Jan 2024.
So I think they are easily first round
They are little bit tough
I prepared last 3 days
I applied via Walk-in and was interviewed before Apr 2020. There was 1 interview round.
A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.
Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.
They consist of two coils of wire, known as the primary and secondary coils, which are wrapped around a magnetic core.
When an AC voltage is applied to the primary coil, it creates a magne...
The type of breaker used depends on the electrical load and the circuit requirements.
The most common types of breakers are standard, AFCI, GFCI, and dual-function.
Standard breakers are used for general-purpose circuits.
AFCI breakers are used for circuits that power bedrooms and living rooms.
GFCI breakers are used for circuits that power bathrooms, kitchens, and outdoor areas.
Dual-function breakers combine AFCI and GFCI...
Conductors are materials that allow electricity to flow through them. There are different types of conductors used in electrical systems.
Copper is the most commonly used conductor in electrical wiring
Aluminum is also used as a conductor, especially in high voltage power transmission
Silver is the best conductor, but it is too expensive for most applications
Gold is also a good conductor, but it is even more expensive tha...
MCB is a miniature circuit breaker while MCCB is a molded case circuit breaker.
MCB is used for low current applications while MCCB is used for high current applications.
MCB is rated up to 100 amps while MCCB can be rated up to 2500 amps.
MCCB has adjustable trip settings while MCB does not.
MCCB is more expensive than MCB.
Examples of MCB brands include Legrand and Schneider while examples of MCCB brands include Siemens a

3 phase systems typically have voltages of 208V, 240V, 480V, or 600V.
3 phase systems can have different voltage levels depending on the application.
Common voltage levels for 3 phase systems include 208V, 240V, 480V, and 600V.
The specific voltage used in a 3 phase system depends on factors such as the power requirements of the equipment being used.
For example, a commercial building may use a 3 phase system with a voltag...
