Hild Energy Interview Questions and Answers

Ductility is the ability of a material to be stretched or drawn into a wire or thread without breaking.

• Ductility is a property of materials that allows them to be deformed under tensile stress.

• Ductile materials can be stretched into thin wires or threads without fracturing.

• Metals like gold, silver, and copper are highly ductile.

• Ductility is measured by the percentage of elongation or reduction in cross-sectional area.

Power transformer protection is necessary to prevent damage to the transformer and ensure continuous power supply.

• Protection against overvoltage, overcurrent, and overheating

• Use of protective relays and fuses

• Ground fault protection

• Differential protection to detect internal faults

• Backup protection in case of failure of primary protection

• Regular maintenance and testing to ensure proper functioning

A single line diagram is a simplified representation of an electrical power system.

• It shows the main components of the system and their interconnections.

• It is used for planning, design, and operation of the system.

• It is a one-line drawing that represents the electrical connections between the components.

• It is used to identify faults and isolate them quickly.

• It is also used to calculate the power flow and voltage drop i
