Kunamneni Technologies Interview Questions and Answers

A PV array is a collection of photovoltaic modules that generate electricity from sunlight.

• PV arrays are commonly used in solar power systems to generate electricity.

• They are made up of multiple PV modules connected together in series or parallel.

• The size of a PV array depends on the amount of electricity needed and the available space for installation.

• PV arrays can be mounted on rooftops, on the ground, or on tracking...read more

A vacuum circuit breaker is an electrical switch that uses a vacuum to extinguish the arc when the circuit is broken.

• It is used in high voltage applications

• It is more efficient and reliable than other types of circuit breakers

• It has a longer lifespan and requires less maintenance

• Examples include Siemens 3AH vacuum circuit breaker and ABB VD4 vacuum circuit breaker

Real response time refers to the time taken for a system to respond to a given input or event.

• Real response time is a measure of system performance.

• It is usually measured in milliseconds or microseconds.

• Factors that affect response time include network latency, processing speed, and system load.

• For example, a website with a low response time will load quickly and provide a better user experience.

• Real response time is d...read more

Inverter duty transformer is designed to handle the high voltage spikes and harmonics generated by inverters.

• Used in applications where inverters are used to convert DC to AC power

• Can handle high voltage spikes and harmonics generated by inverters

• Designed with special insulation and cooling systems to withstand the stress of inverter operation

• Examples include solar power systems, wind turbines, and variable speed drive...read more

Maximum power point tracking is a technique used to optimize the output power of a solar panel.

• It involves finding the point on the current-voltage curve of a solar panel where the output power is maximum.

• This is done by adjusting the load resistance of the panel to match the impedance of the solar cells.

• MPPT is important for maximizing the efficiency of solar panels and increasing the amount of power that can be gener...read more
