Interview Questions for Power Line Installation

Power lines are categorized based on voltage level and application. Think of it like roads – you have small residential streets, larger city roads, and then massive highways. Similarly, we have different types of power lines to handle varying power demands.

• Low-Voltage Lines (LV): These lines typically operate at voltages below 1000 volts and distribute electricity to individual homes and small businesses. They’re like the smaller residential streets in our analogy, handling lower traffic (power demand).
• Medium-Voltage Lines (MV): Operating between 1 kV and 35 kV, these lines connect substations to distribution transformers, feeding power to larger areas. Imagine these as the city roads, handling a significant amount of traffic.
• High-Voltage Lines (HV): These lines operate at voltages ranging from 35 kV to 230 kV and transmit electricity over long distances from power plants to substations. These are our highways, transporting massive amounts of power efficiently across vast distances.
• Extra-High-Voltage Lines (EHV) and Ultra-High-Voltage Lines (UHV): These are specialized lines used for transmitting very large amounts of power across extremely long distances, often exceeding 230 kV and sometimes reaching millions of volts. These are the specialized expressways, optimized for incredibly high capacity.

The choice of line type depends on the voltage requirements, distance of transmission, and power demand of the area it serves. For example, a new housing development would primarily use low-voltage lines, while a large industrial park might require medium-voltage lines, and a transmission line connecting a remote power plant to a major city would utilize high-voltage or even extra-high-voltage lines.

Safety is paramount when working with high-voltage power lines. A single mistake can be fatal. We follow a strict hierarchy of safety protocols, often exceeding OSHA regulations. Imagine handling a coiled venomous snake – extreme caution and specific procedures are absolutely necessary.

• Lockout/Tagout (LOTO): Before any work begins, the power must be completely de-energized and locked out to prevent accidental re-energization. This involves physically locking out the circuit breaker to prevent anyone from turning the power back on unintentionally.
• Grounding: The lines must be thoroughly grounded using specialized grounding equipment to ensure that any residual charge is safely dissipated into the earth. This is crucial to prevent electric shock.

Power line conductors need to handle massive electrical currents and withstand environmental stresses. Think of them as the arteries of the power grid. We select conductors based on several factors.

• Aluminum Conductor Steel-Reinforced (ACSR): This is the most common type, combining the lightweight and good conductivity of aluminum with the strength of steel core wires. It balances weight, strength, and conductivity.
• All-Aluminum Conductor (AAC): Used in lower-voltage applications, AAC offers good conductivity but is less strong than ACSR. It’s suitable for lower stress environments.
• Aluminum Conductor Alloy Steel-Reinforced (ACAR): This type offers improved tensile strength and resistance to corrosion compared to ACSR.
• Copper Conductors: While offering superior conductivity to aluminum, copper is more expensive and heavier. It’s primarily used in situations demanding higher current-carrying capacity or lower resistance.

The selection depends on factors like voltage level, current capacity requirements, span length, environmental conditions (wind, ice, etc.), and cost considerations. For instance, long spans with high wind loads might require ACSR, while shorter spans with lower loads might use AAC. Careful conductor selection is crucial to ensure efficient power transmission and long-term reliability.

Identifying and resolving power line faults is a critical aspect of maintaining a reliable power grid. Think of it as diagnosing a patient – we need to identify the symptoms and address the root cause.

Common faults include:

• Broken Conductors: These can be identified visually or through testing. Repairs involve splicing the broken conductor or replacing the section.
• Loose Connections: Poor connections can lead to overheating and potential fires. They are often detected through infrared thermography (heat detection) or by measuring voltage drops.
• Insulator Failures: Damaged insulators can cause short circuits. They’re often identified through visual inspection or by observing arcing or sparking.
• Tree Contact: Trees growing too close to power lines can cause short circuits or grounding faults. This requires tree trimming or removal.
• Lightning Strikes: These can damage insulators, conductors, or other equipment. Repairs often involve replacing damaged components.

Fault identification uses various methods including visual inspections, infrared thermography, electrical testing, and sophisticated monitoring systems.
