The vector group of a delta-star step down transformer is Yd11.
The vector group Yd11 indicates that the primary winding is connected in delta (Y) and the secondary winding is connected in star (d) with a phase shift of 30 degrees.
Yd11 is a common vector group for step down transformers used in distribution systems.
Understanding the vector group is important for proper connection and operation of transformers.
I applied via Company Website and was interviewed before Nov 2020. There were 4 interview rounds.
Substation protection includes overcurrent, earth fault, differential, distance, and backup protection.
Overcurrent protection is used to detect and isolate faults caused by excessive current flow.
Earth fault protection is used to detect and isolate faults caused by current leakage to earth.
Differential protection is used to detect and isolate faults between two parts of a system.
Distance protection is used to detect an...

GTAW and TIG welding are the same process, with GTAW being the technical term and TIG being the commonly used name.
GTAW stands for Gas Tungsten Arc Welding, while TIG stands for Tungsten Inert Gas welding.
Both processes use a non-consumable tungsten electrode to create an arc for welding.
GTAW and TIG welding are often used interchangeably, with TIG being the more commonly used term in industries.
The main difference lie...
A Mahanagar gas network diagram with pressure variation needs to be drawn for the Project Engineer interview.
The diagram should include all the pipelines and their respective pressure levels.
The pressure variation should be shown using different colors or shades.
The diagram should also include the location of gas stations and regulators.
The pressure levels should be labeled and explained in a legend.
The diagram should
Risk is the likelihood of harm or loss, while hazard is the potential source of harm or danger.
Risk refers to the probability of an event occurring and the potential consequences of that event.
Hazard is anything that has the potential to cause harm, such as chemicals, machinery, or natural disasters.
Identifying and managing risks and hazards is important in ensuring safety and preventing accidents.
Examples of hazards i...
Methane is a chemical compound with the molecular formula CH4.
Methane is the simplest hydrocarbon.
It is a colorless, odorless gas.
It is highly flammable and burns with a blue flame.
Methane is the main component of natural gas.
It is produced naturally by anaerobic digestion of organic matter.
Methane is used as a fuel for heating and cooking.
It is also used as a feedstock for the production of chemicals such as methanol
The pipe diameter used in Mahanagar Gas varies depending on the specific project requirements.
The pipe diameter used in Mahanagar Gas projects is determined based on factors such as gas flow rate, pressure, and distance.
For high-pressure gas transmission pipelines, larger diameter pipes are typically used to minimize pressure drop.
In distribution pipelines, smaller diameter pipes are used to supply gas to individual co...
I applied via Approached by Company and was interviewed before Apr 2021. There were 4 interview rounds.
This has two papers one technical and one non technical
Technical has only two subjects machines and power systems 100 ques 1 hour.
Non technical exam has 50 ques 1/2hour.
Questions related to electrical engineering concepts such as star delta connection, distribution transformer, color coding of conductor, earthing vs grounding, machine efficiency and stability.
Star delta connection is a method of starting three-phase induction motors.
Distribution transformer is used to step down high voltage to low voltage for distribution purposes.
Color coding of conductor is used to identify the func...
