Autotech Industries Electrical Maintenance Engineer Interview Questions and Answers

A synchronisation panel for DG is used to synchronize multiple generators to ensure they are running in parallel and sharing the load evenly.

• Synchronisation panels are used in situations where multiple diesel generators need to be connected in parallel to supply power to a common bus.

• The panel monitors the frequency, voltage, and phase angle of each generator and ensures they are synchronized before connecting them to ...read more

Pulse width in laser refers to the duration of time that a laser beam is emitted.

• Pulse width is measured in seconds or milliseconds.

• It determines the amount of energy delivered by the laser beam.

• Shorter pulse widths are often used for precision cutting or welding.

• Longer pulse widths are used for applications like material processing or drilling.

BDV stands for Breakdown Voltage. It is a measure of the dielectric strength of transformer oil.

• BDV is the voltage at which the insulation between two conductors breaks down.

• It is an important parameter to determine the quality of transformer oil.

• BDV is usually measured in kilovolts (kV).

• Higher BDV indicates better quality and higher dielectric strength of the oil.

RTCC panel stands for Remote Tap Changing Control panel, used in power transformers to automatically adjust the voltage ratio.

• RTCC panel monitors the load and voltage levels of the transformer.

• It automatically adjusts the tap changer to maintain the desired voltage ratio.

• RTCC panel can be programmed to operate based on specific parameters like load current, temperature, etc.

• It helps in optimizing the transformer perfor...read more
