JUNIPER GREEN ENERGY Interview Questions, Process, and Tips

Power transformers are protected by various mechanisms to ensure safe operation and prevent damage.

• Overcurrent protection: Protects against excessive current flow.

• Overvoltage protection: Safeguards against high voltage spikes.

• Temperature monitoring: Prevents overheating by shutting down the transformer if temperature exceeds safe limits.

• Buchholz relay: Detects internal faults such as insulation breakdown or oil leakage...read more

A single line diagram is a simplified representation of an electrical power system using symbols to show the connections between components.

• Shows the flow of electrical power in a system

• Uses standardized symbols for components like transformers, generators, and circuit breakers

• Helps in understanding the overall layout of the system

• Does not show the physical location of components, only their connections

M25 concrete strength is a common grade used in construction projects.

• M25 concrete has a compressive strength of 25 megapascals after 28 days of curing.

• It is commonly used in residential construction for foundations, slabs, and columns.

• Proper mix design, curing, and testing are essential to achieve the desired strength.

• Quality control measures should be implemented to ensure the strength requirements are met.

Road FDD test value is a measure of the stiffness of the road surface.

• Road FDD test value stands for Falling Weight Deflectometer test value.

• It is used to assess the structural condition of the road pavement.

• Higher FDD values indicate a stiffer pavement, while lower values indicate a more flexible pavement.

• FDD values are typically measured in millimeters or inches.

• The test involves dropping a weight onto the road surfa...read more

BOP stands for Blowout Preventer, a crucial safety device used in drilling operations to prevent uncontrolled release of oil or gas.

• BOP is a large valve system installed on top of a wellbore to control pressure and prevent blowouts.

• It consists of multiple components such as annular preventers, ram preventers, and control systems.

• BOPs are used in offshore and onshore drilling operations to ensure safety and prevent envi...read more
