Isgec Hitachi Zosen Interview Questions, Process, and Tips

The duty cycle of a power contractor refers to the amount of time it can operate continuously without overheating or needing to cool down.

• The duty cycle is typically expressed as a percentage, representing the ratio of operating time to the total time.

• For example, a power contractor with a duty cycle of 50% can operate for 5 minutes and then needs to cool down for 5 minutes before being used again.

• A higher duty cycle i...read more

A drive is a device that reads or writes data on a storage medium. Types include hard disk, solid-state, optical, and flash drives.

• A drive is a hardware component that allows data to be stored and retrieved from a storage medium.

• Hard disk drives use spinning disks to read and write data, while solid-state drives use flash memory.

• Optical drives use lasers to read and write data on CDs, DVDs, and Blu-ray discs.

• Flash driv...read more

Efficiency of motor can be measured by conducting a load test and measuring the input and output power.

• Conduct a load test by connecting the motor to a dynamometer

• Measure the input power using a wattmeter

• Measure the output power using a torque meter and a speedometer

• Calculate the efficiency using the formula: Efficiency = (Output Power/Input Power) x 100%

• Compare the calculated efficiency with the standard efficiency fo

To identify the type of breakdown in a solenoid valve, one can perform visual inspection, check for electrical continuity, and conduct voltage and resistance tests.

• Perform a visual inspection to check for any visible signs of damage or wear on the solenoid valve.

• Check for electrical continuity by using a multimeter to test the continuity between the electrical connections of the solenoid valve.

• Conduct voltage tests by ...read more
