20 Electrical Engineering Interview Questions & Answers This is a must know question for any good Electrical Engineer Download PDF. ELECTRICAL INTERVIEW QUESTIONS AND ANSWERS. Visit osakeya.info more resources. 1. What happens if I connect a capacitor to a generator load?. Here we are providing great collection of Electrical Engineering Technical and HR Interview Questions And Answers osakeya.info have made it for.
All the electronic devices around us and the electrical machinery use a combination of different principles and concepts to function. But to be specific in a differentiating sense, the entire branch can be sub divided based on the specific area they cater to such as- Digital computers, Control Systems, Telecommunications, Power engineering, RF Radio Frequency Engineering, Signal Processing, Microelectronics and Instrumentation to name a few.
Each of these branches holds it s own importance and relevance to the subject as a whole in its own unique way. It is no ordinary task as such to be able to win over the interviewer without any technical knowledge about the subject of interest.
Most of the companies that look to employ electrical engineers, be it corporate firms or large public sector establishments look for a crystal clear understanding of the science in a potential employee. To be able to meet this criteria, a student must be able to impress the interviewer with his strong grasp over the concepts and principles.
ODWF oil direct, water forced 5. OFAN oil forced, air forced Electrical interview question: What is the function of anti-pumping in circuit breaker? Answer: when breaker is close at one time by close push button he anti pumping contactor prevent re close the breaker by close push button after if it already close. Electrical interview question: what is stepper motor.
What is its uses? Answer :Stepper motor is the electrical machine which act upon input pulse applied to it. It is important part in Synchronous Generators; it controls the output voltage of the generator by controlling its excitation current. Thus it can control the output Reactive Power of the Generator. Electrical interview question: What is an exciter and how does it work? Answer: There are two types of exciters, static exciter and rotary exciter.
Purpose of exciter is to supply the excitation dc voltage to the fixed poles of generator. Rotory exciter is an additional small generator mounted on the shaft of main generator. K is the ac generator whose field winding are stationary and armature rotates.
It gives the starting torque to the generator. Electrical interview question: Difference between a four point starter and three point starter? Answer: The shunt connection in four point starter is provided separately from the line where as in three point state it is connected with line which is the drawback in three point starter Electrical interview question: Why use the VCB at High Transmission System?
Why can't use ACB?
Answer: Actually the thing is vacuum has high arc quenching property compare to air becoz in VCB ,the die electric strength is equal to 8 times of air. That y always vacuum used as in HT breaker and air used as in LT.
Electrical interview question: What is the difference between surge arrestor and lightning arrestor? Answer: LA is installed outside and the effect of lightning is grounded, where as surge arrestor installed inside panels comprising of resistors which consumes the energy and nullify the effect of surge.
Electrical interview question: Why syn.
Answer: synchronous machines have capability to work on different power factor or say different imaginary power varying the field emf. Hence syn.
Answer: In simple, synchronous generator supply's both active and reactive power but asynchronous generator induction generator supply's only active power and observe reactive power for magnetizing.
This type of generators is used in windmills. To fix the reverse polarity, check the wire connection at the outlet and inspect your receptacle.
A receptacle with reverse polarity will have the white wire screwed to the hot side and the black wire will be connected to the neutral side, if that the case swap the wires and it will resolves the problem. If it persists, a licensed electrician will be needed. A rectifier is an electrical device that transforms A. C , which flows in only one direction.
The types of rectifiers are. Zener diode is a type of seme-conductor diode that allows current to flow in the opposite direction when exposed to enough voltage. Laser diodes are compact transistor like packages with two or more electrical leads. Lasing occurs when stimulated emission results into the amplification of photon confined to the lasing mode.
