Promho Energy Interview Questions and Answers

HVDC stands for High Voltage Direct Current. It is a system used for transmitting high voltage electricity over long distances.

• HVDC systems are used to transmit electricity over long distances with minimal losses.

• They are more efficient than traditional AC systems for long-distance transmission.

• HVDC systems use converters to convert AC power to DC power and vice versa.

• Examples of HVDC systems include the Itaipu HVDC sy...read more

A rectifier is an electronic device that converts AC to DC.

• Rectifiers are commonly used in power supplies to convert AC voltage to DC voltage.

• They can be made using diodes or other semiconductor devices.

• Rectifiers are essential for many electronic devices to function properly.

• Examples of rectifiers include bridge rectifiers, half-wave rectifiers, and full-wave rectifiers.

To analyse total diesel consumption in equipment, I would gather data on usage and calculate fuel efficiency.

• Collect data on equipment usage and fuel consumption

• Calculate fuel efficiency by dividing fuel consumption by equipment usage

• Compare fuel efficiency across different equipment to identify outliers

• Identify factors that may affect fuel efficiency, such as maintenance or operator behavior
