Finding the right expert with in-depth knowledge of electricity and circuits for your business isn’t easy. Do they know the difference between a series and a parallel circuit? Have they worked with AC circuits before?
There are, however, two main ways to tell if their skills are enough for the job you want to fill:
Below, we’ve provided 73 interview questions to help you prepare for interviewing your candidates. All the questions you need are here – along with some sample answers to review applicants’ responses.
You want to work in the exciting field of electric power? That’s great! It’s a field that’s always changing and growing, and it’s a big part of how our homes, businesses, and industries get power. Here are 5 common electric power interview questions and their expertly written answers to help you ace your next one. Let’s get charged up!.
1 What is the Power plant or Power Station?
Power plants also known as power stations, are the heart of our electrical system. They generate electricity by converting various energy sources, such as coal natural gas, nuclear power, or renewable sources like solar and wind, into electrical energy. This electricity is then transmitted through a network of power lines to homes, businesses, and industries.
2 What do you mean by the zone of protection?
The zone of protection refers to the area surrounding a power system component, such as a transformer or a transmission line, that is protected by a relay system. This relay system monitors the electrical parameters of the component and trips circuit breakers to isolate the component from the rest of the system in case of a fault. This helps to prevent damage to the component and to maintain the integrity of the power system.
3, What is the difference between the Transmission line and distribution line?
In order to get electricity from power plants to substations over long distances, transmission lines are used. They typically operate at voltages of 138 kV or higher. Less powerful power lines called distribution lines bring electricity from substations to homes, businesses, and factories. They typically operate at voltages of 12 kV or lower.
4. What are the common sources of energy?
The common sources of energy can be broadly classified into two categories renewable and non-renewable. Renewable energy sources such as solar, wind hydro, and geothermal, are replenished naturally and can be used sustainably. Non-renewable energy sources, such as coal, natural gas, and oil, are finite resources that will eventually be depleted.
5. Write down the classification of the transmission line?
Transmission lines can be classified based on various factors, including voltage level, conductor material, and tower type. Based on voltage level, transmission lines can be classified as high-voltage (HV), extra-high-voltage (EHV), or ultra-high-voltage (UHV) lines. Based on conductor material, transmission lines can be classified as overhead lines or underground cables. Overhead lines are typically made of aluminum or copper conductors, while underground cables are typically made of insulated copper or aluminum conductors. Based on tower type, transmission lines can be classified as lattice towers, monopole towers, or guyed towers.
Bonus Tip:
To further impress your interviewer, demonstrate your knowledge of current trends and challenges in the electric power industry, such as the increasing adoption of renewable energy sources, the development of smart grids, and the need for cybersecurity measures to protect critical infrastructure.
By understanding these key concepts and showcasing your enthusiasm for the electric power industry, you’ll be well on your way to landing your dream job!
Name a technical skill you’re trying to perfect as an electrical engineer
Applicants must work toward mastering their technical skills to perform professionally at every job.
For instance, they might need to brush up on their health and safety skills or learn more about the basics of electrical engineering. Before you hire someone, make sure they’re doing what they need to do to learn these skills. For example, they could take a course or do work that will give them the experience they need.
In which situation would you use a thyristor?
There are several situations when electrical engineers may choose to use a thyristor.
As an example, a thyristor is a great choice if they want to lower the cost of controlling speed or alternating current. Candidates may also explain that they could use thyristors in high-current and high-voltage applications.
