Aavran SALES Agency Interview Questions and Answers

If copper taping becomes brittle, it may lead to poor electrical conductivity, increased risk of breakage, and potential failure of the system.

• Poor electrical conductivity may result in signal loss or interference.

• Increased risk of breakage can lead to physical damage to the system.

• Potential failure of the system may require costly repairs or replacements.

• Brittle copper taping may also indicate corrosion or degradation of the material.

Preventive maintenance involves checking various components to ensure they are in good working condition.

• Inspecting and cleaning filters to ensure proper airflow

• Checking and replacing worn out belts and hoses

• Testing and replacing batteries if necessary

• Inspecting and lubricating moving parts

• Checking for leaks and addressing them promptly

Busbars are shaped rectangular instead of cylindrical for better heat dissipation and easier installation.

• Rectangular shape provides more surface area for heat dissipation

• Easier to stack and connect rectangular busbars in electrical panels

• Rectangular shape allows for more efficient use of space in the panel

• Cylindrical shape would be harder to install and connect in a panel

Gravelling in substations is used to provide a stable surface for equipment installation, reduce the risk of electric shock, and prevent weed growth.

• Provides a stable surface for equipment installation

• Reduces the risk of electric shock by providing insulation

• Prevents weed growth around the equipment

• Improves drainage and reduces the risk of flooding

• Helps in maintaining a clean and organized substation environment

The dimensions of an 11 KV VCB vary depending on the manufacturer and model, typically ranging from 600mm x 400mm x 200mm to 800mm x 600mm x 300mm.

• Dimensions can vary based on manufacturer and model

• Common dimensions range from 600mm x 400mm x 200mm to 800mm x 600mm x 300mm

• VCB stands for Vacuum Circuit Breaker

Copper taping in HT cables provides shielding against electromagnetic interference and helps in grounding.

• Copper taping in HT cables acts as a shield to protect against electromagnetic interference.

• It helps in grounding the cable to prevent electrical hazards.

• The copper taping also provides mechanical protection to the cable.

• Example: Copper taping is commonly used in high voltage power cables to ensure reliable transmission of electricity.
