CTEVT Electrical Instructor Mock Exam: Practice for Success in Nepal

Prepare effectively for your CTEVT Electrical Instructor examination with our comprehensive mock exam, meticulously structured to mirror the official syllabus. This practice test is an invaluable resource for aspiring electrical instructors in Nepal, helping you master key concepts in:

• D.C. & A.C. Circuit Analysis: Fundamental principles of current, voltage, resistance, Ohm's Law, Kirchhoff's Laws, RMS values, power factor, and three-phase systems.

• Electrical Machines: In-depth coverage of transformers, DC machines (commutation, EMF equation, starting methods), induction motors (slip, no-load test), and synchronous motors (hunting, power factor operation).

• Transmission & Distribution: Essential topics like corona effect, sag, Ferranti effect, transmission line modeling (ABCD constants), and the advantages of HVDC.

• Switchgear and Protection: Understand the critical role of fuses, MCBs, VCBs, Buchholz relays, lightning arresters, earth fault relays, and contactors in electrical safety and system protection.

• Power Plants: Explore different types of power generation including hydro (Pelton turbine, micro hydro), diesel, solar PV, and steam power plants, along with concepts like AVR and load factor.

• Measurements and Instruments: Learn about PMMC instruments, wattmeters, current transformers (CT), meggers, and earth testers for accurate electrical measurements.

• Power Electronics: Dive into SCRs, rectifiers (full-wave), buck and boost converters, inverters (PWM techniques), cyclo-converters, MOSFETs, and power device characteristics.

• Control Systems and Controllers: Grasp the principles of feedback, transfer functions, block diagrams, proportional, integral, and derivative controllers, as well as stability analysis using Routh-Hurwitz and root locus.

• Utilization of Electrical Energy: Understand power factor, diversity factor, and the working principles of incandescent and fluorescent lamps.

• Power System Stability and Load Flow: Key concepts including the swing equation, power angle curve, steady-state and transient stability (equal area criterion), critical clearing angle, and load flow analysis methods (Gauss-Seidel, Newton-Raphson, Fast Decoupled).

• Electrical Installation and Wiring: Practical knowledge on loop-in method, PVC wiring, Tee system, conduit wiring, main distribution boards, earthing, fuse rating, ELCB, and thermal overload relays.

• General Safety and National Codes: Crucial safety measures, neutral grounding, lightning protection, and adherence to national safety regulations in Nepal, including the National Grid Code.
