Transmission Lead Interview Questions and Answers

The pole to pole distance in a short solar PV transmission system varies depending on the specific installation and requirements.

• The pole to pole distance is determined by factors such as the location, terrain, and available space for installation.

• In urban areas, the pole to pole distance may be shorter due to limited space.

• In rural or open areas, the pole to pole distance can be longer to accommodate larger solar arrays.

• The pole to pole distance also depends on the voltage a...read more

The types of insulators used in distribution lines include pin insulators, suspension insulators, and strain insulators.

• Pin insulators are used to support the conductor on the pole or tower.

• Suspension insulators are used to hang the conductor from the crossarm.

• Strain insulators are used to provide mechanical support and electrical insulation at the ends of the conductor spans.

• Other types of insulators used in distribution lines include shackle insulators, guy strain insulator...read more

The cable used for 25 to 30 KWp solar mini grid transmission line is typically an aluminum or copper conductor cable.

• Aluminum or copper conductor cables are commonly used for solar mini grid transmission lines.

• The cable size and type may vary depending on the specific requirements of the installation.

• For higher power transmission, larger cable sizes may be necessary to minimize power losses.

• Examples of commonly used cables for solar mini grid transmission lines include alumin...read more

MW (megawatt) is a unit of power equal to one million watts, and frequency refers to the rate at which a periodic event occurs.

• MW is a measure of power, while frequency is a measure of how often a periodic event occurs

• In the context of electricity transmission, MW with frequency refers to the amount of power being transmitted and the frequency of the alternating current

• For example, a power plant may generate 100 MW of electricity at a frequency of 60 Hz
