Nextsquare Technologies Interview Questions and Answers

Traveling is the movement of electrical energy from one point to another in a substation.

• Traveling is important in substations to distribute electrical energy to different parts of the substation.

• It is necessary to ensure that the energy is distributed evenly and efficiently.

• Traveling is achieved through the use of transformers, circuit breakers, and other electrical equipment.

• It is also important to monitor traveling to prevent overloading and ensure safety.

• Examples of trave...read more

Transmission lines are used to transfer electrical energy from power plants to substations and distribution lines.

• Transmission lines are high voltage power lines that can span hundreds of miles.

• They are used to transport electricity from power plants to substations and distribution lines.

• Transmission lines are typically made of steel or aluminum and are supported by tall towers.

• The voltage on transmission lines can range from 69 kV to 765 kV.

• Transmission lines can be overhead...read more

There are mainly four types of transmission line towers: suspension, tension, angle, and dead-end towers.

• Suspension towers are used to support the high voltage transmission lines over a long span.

• Tension towers are used to support the high voltage transmission lines when the line changes its direction.

• Angle towers are used to support the high voltage transmission lines when the line changes its direction at an angle.

• Dead-end towers are used to support the high voltage transmi...read more

DC motors and AC induction motors are commonly used for traction purpose.

• DC motors are used in electric trains, trams, and trolleybuses.

• AC induction motors are used in electric cars and hybrid vehicles.

• Traction motors are designed to provide high torque at low speeds.

• The motor must be able to handle the high starting currents and frequent stops and starts.

• Regenerative braking is used to recover energy during braking and feed it back into the power grid.

An ICT is an interconnecting transformer used to connect two different power systems.

• ICTs are used to connect power systems with different voltage levels.

• They are also used to isolate different parts of a power system.

• ICTs can be used to provide galvanic isolation between two systems.

• They are commonly used in power substations and industrial settings.

• Examples of ICTs include autotransformers and isolation transformers.

Proper tension and pressure are required to prevent conductor snapping.

• Tension must be maintained within the allowable range for the conductor.

• Proper sagging of the conductor must be ensured.

• The conductor must be free from any defects or damages.

• The temperature of the conductor must be monitored to prevent overheating.

• The conductor must be properly supported and secured.

• The pressure on the conductor must be evenly distributed.

• Proper insulation must be provided to prevent any ...read more

PEEP stands for Positive End-Expiratory Pressure.

• PEEP is a medical term used in respiratory therapy.

• It refers to the pressure maintained in the airways at the end of exhalation.

• PEEP is commonly used to treat patients with respiratory distress or acute respiratory failure.

• It helps to keep the alveoli open and improve oxygenation.

• Examples of PEEP settings include 5 cmH2O or 10 cmH2O.

Right of way can be resolved through communication, signage, and following traffic laws.

• Communicate with other drivers and pedestrians to establish who has the right of way

• Use clear signage to indicate right of way, such as stop signs or yield signs

• Follow traffic laws and regulations to ensure safe and efficient flow of traffic

• In some cases, right of way may be determined by the type of vehicle or the direction of travel

• Be aware of blind spots and always proceed with caution
