Essential Interview Questions For Electrical Wiring Lineman
1. Describe the steps involved in installing a new overhead power line.
The steps involved in installing a new overhead power line are as follows:
- Plan the route of the power line, taking into account the location of existing infrastructure, environmental factors, and safety considerations.
- Acquire the necessary permits and approvals from local authorities.
- Survey the route of the power line to determine the exact location of poles and other structures.
- Install the poles and other structures that will support the power line.
- String the conductors (wires) between the poles.
- Connect the conductors to the power source and to the load.
- Test the power line to ensure that it is safe and functioning properly.
2. What are the safety precautions that must be taken when working on an energized power line?
Electrical Safety Precautions
- Wear appropriate personal protective equipment (PPE), including rubber gloves, safety glasses, a hard hat, and flame-resistant clothing.
- Use insulated tools.
- Maintain a safe distance from energized conductors.
- Be aware of the location of overhead power lines and underground cables.
- Never touch an energized power line.
Non-Electrical Safety Precautions
- Be aware of the weather conditions and take precautions to avoid working in hazardous conditions.
- Work with a partner or in a team.
- Use proper lifting techniques.
- Be aware of the location of other workers and equipment.
3. How do you troubleshoot a power outage on an overhead power line?
To troubleshoot a power outage on an overhead power line, the following steps should be taken:
- Check the power source to ensure that it is functioning properly.
- Check the power line for any visible damage, such as broken conductors or loose connections.
- Use a voltmeter to check the voltage at various points along the power line.
- If the voltage is low or zero at a certain point, this indicates that there is a break in the power line.
- Once the location of the break has been identified, the power line can be repaired and power restored.
4. What are the different types of conductors used in overhead power lines?
The different types of conductors used in overhead power lines include:
- Bare copper conductors
- Insulated copper conductors
- Aluminum conductors
- Aluminum conductor steel-reinforced (ACSR)
- Composite conductors
The type of conductor used in a particular power line will depend on factors such as the voltage of the line, the distance between the poles, and the environmental conditions.
5. What are the advantages and disadvantages of using composite conductors in overhead power lines?
The main advantages of using composite conductors in overhead power lines include:
- They have a higher strength-to-weight ratio than traditional conductors, which means that they can span longer distances between poles.
- They are less susceptible to vibration and fatigue, which can extend their lifespan.
- Their smooth surface reduces wind resistance, which can reduce the risk of damage during storms.
The main disadvantage of using composite conductors is that they are more expensive than traditional conductors.
6. What is the purpose of a lightning arrester on an overhead power line?
The purpose of a lightning arrester on an overhead power line is to protect the power line and its equipment from damage caused by lightning strikes.
Lightning arresters work by providing a low-resistance path to ground for lightning currents. This diverts the lightning current away from the power line and its equipment and into the ground, where it can be safely discharged.
7. What are the different types of insulators used in overhead power lines?
The different types of insulators used in overhead power lines include:
- Pin insulators
- Suspension insulators
- Strain insulators
The type of insulator used in a particular power line will depend on factors such as the voltage of the line, the distance between the poles, and the environmental conditions.
8. What is the purpose of a guy wire on an overhead power line?
The purpose of a guy wire on an overhead power line is to provide additional support to the pole and prevent it from falling over. Guy wires are typically used on poles that are located in areas with high winds or other environmental hazards.
9. What are the different types of crossarms used in overhead power lines?
The different types of crossarms used in overhead power lines include:
- Single crossarms
- Double crossarms
- Triple crossarms
The type of crossarm used in a particular power line will depend on factors such as the number of conductors that are being carried on the line and the distance between the poles.
10. What is the purpose of a transformer on an overhead power line?
The purpose of a transformer on an overhead power line is to change the voltage of the electricity that is being transmitted. Transformers are used to step up the voltage of electricity before it is transmitted over long distances, and to step down the voltage of electricity before it is distributed to homes and businesses.
