NTPC Diploma Trainee in C&I syllabus

Will you please provide the National Thermal Power Corporation Diploma Trainee Communication Engineering & Instrumentation exam syllabus?

[Arun Vats]

The NTPC Diploma Trainee syllabus of C&I (Communication Engineering & Instrumentation) branch is as follows:

• Basic Electronics/ Power Electronics
• Analog Electronics
• Networking/ computer networks
• Field instrumentation system
• Control valves and on/off valves
• Cabling
• Power Electronics & Drives
• Sensors & Transducers
• Measurement & Instrumentation
• Circuit Theory/ Digital Electronics
• Open/Closed/Cascade loop control
• PID controlling & tuning
• Pneumatic control
• Basic Data Acquisition Systems
• PLC/DCS/SCADA

For your idea , here I am providing the list of few NTPC Diploma trainee C&I questions .
