AVON TUBETECH Interview Questions and Answers

A star-delta diagram illustrates a method for reducing the starting current of three-phase induction motors.

• The star-delta starter connects the motor in star configuration during startup to limit current.

• After a few seconds, it switches to delta configuration for normal operation, allowing full power.

• This method is commonly used for large motors (e.g., 10 HP and above) to prevent electrical stress.

• The diagram typically...read more

Understanding load capacity is crucial for maintenance engineers to ensure equipment operates efficiently and safely.

• Full load current (FLC) is the maximum current a motor can draw under full load conditions.

• For example, a 10 HP motor at 460V has an FLC of approximately 12.5 amps.

• Calculating load helps in selecting appropriate circuit breakers and wiring.

• Consider factors like power factor and efficiency when determinin...read more
