Gallantt Ispat DCS Engineer Interview Questions and Answers

Equipments used in blast furnaces include stoves, hot blast valves, tuyeres, bustle pipes, and skip hoists.

• Stoves - used to preheat the air blast before it enters the furnace

• Hot blast valves - control the flow of hot air into the furnace

• Tuyeres - nozzles through which the hot air is injected into the furnace

• Bustle pipes - distribute the hot air evenly throughout the furnace

• Skip hoists - used to transport materials in a

Power factor is the ratio of real power to apparent power in an AC circuit. VFD stands for Variable Frequency Drive. AC motors run on alternating current while DC motors run on direct current.

• Power factor is a measure of how effectively electrical power is being used in a circuit.

• It is calculated by dividing the real power (in watts) by the apparent power (in volt-amperes).

• A power factor of 1 indicates that all the pow...read more

Types of load cells include strain gauge load cells, hydraulic load cells, and capacitive load cells.

• Strain gauge load cells measure the strain or deformation of a material.

• Hydraulic load cells use hydraulic fluid to measure force.

• Capacitive load cells measure changes in capacitance to determine force.

• Other types of load cells include piezoelectric load cells and pneumatic load cells.

Different types of protection are used in a substation to ensure safety and reliability.

• Overcurrent protection: Protects against excessive current flow.

• Overvoltage protection: Safeguards against high voltage surges.

• Differential protection: Detects faults by comparing currents entering and leaving the substation.

• Distance protection: Protects transmission lines based on the distance to the fault.

• Ground fault protection: ...read more

Different types of HT breakers are used in HT lines depending on the specific requirements.

• Air Circuit Breaker (ACB) is commonly used in HT lines for its high breaking capacity and quick response time.

• Vacuum Circuit Breaker (VCB) is another popular choice due to its compact size and low maintenance requirements.

• SF6 Circuit Breaker is used for high voltage applications as it provides excellent arc quenching properties.

• O...read more

Siemens plc OB, FB, FV, and DB are different types of blocks used in programming Siemens PLCs.

• OB (Organization Block) is used for organizing and controlling the program execution.

• FB (Function Block) is used for creating reusable functions or subroutines.

• FV (Function Value) is used for passing parameters to function blocks.

• DB (Data Block) is used for storing and managing data in the PLC program.

The number of relays in transfer protection varies depending on the specific system and requirements.

• The number of relays in transfer protection can range from a few to several dozen, depending on the complexity of the system.

• Relays are used in transfer protection to detect faults, isolate faulty sections, and ensure smooth transfer of power.

• Examples of relays used in transfer protection include differential relays, di

The interview questions cover topics such as grades of bolts, bearing types, types of oil and grease, iron carbon diagram, hydraulic systems, and hydraulic hose pipe nomenclature.

• HT bolt grades are determined based on the material and strength requirements, such as Grade 8.8 or Grade 10.9.

• Bearing definition: Bearings are components that support and guide moving parts, with types including ball bearings, roller bearings...read more
