Sidel Electrical Engineer Interview Questions and Answers

RTD and TC are used for temperature measurement in various industries.

• RTD stands for Resistance Temperature Detector and TC stands for Thermocouple.

• RTD measures temperature by sensing the change in resistance of a metal wire as temperature changes.

• TC measures temperature by sensing the voltage generated by the junction of two dissimilar metals.

• RTD is more accurate and stable than TC, but TC is more rugged and can measu...read more

Variable frequency drives (VFDs) are used in ID fan motor and cooler motor.

• VFDs are used to control the speed of the motor and save energy.

• ID fan motor and cooler motor require different speeds at different times, which can be achieved through VFDs.

• VFDs can also protect the motor from damage due to overvoltage or undervoltage.

• Examples of VFDs include ABB ACS880, Siemens Sinamics G120, and Schneider Electric Altivar Pro
