Dab Hand Solutions 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

Modulation is the process of varying a carrier signal to transmit information. Types include amplitude modulation, frequency modulation, and phase modulation.

• Modulation is the process of varying a carrier signal to transmit information

• Types of modulation include amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM)

• AM varies the amplitude of the carrier signal based on the input signal

• FM varies the frequency of the carrier signal based on the input si...read more

Voltage is the potential difference between two points in a circuit, while current is the flow of electric charge through a conductor.

• Voltage is measured in volts (V) and represents the potential energy difference between two points in a circuit.

• Current is measured in amperes (A) and represents the flow of electric charge through a conductor.

• Voltage is analogous to the pressure in a water pipe, while current is analogous to the flow rate of water through the pipe.

• Ohm's Law re...read more
