Nextgen Fibres Interview Questions, Process, and Tips

Voltage can be controlled through various methods such as using voltage regulators, transformers, and power factor correction.

• Voltage regulators are electronic devices that maintain a constant voltage level regardless of input fluctuations.

• Transformers can step up or step down voltage levels depending on the application.

• Power factor correction techniques can be employed to improve voltage stability and efficiency.

• Volta...read more

AC stands for Alternating Current and DC stands for Direct Current.

• AC is a type of electrical current that periodically changes direction.

• DC is a type of electrical current that flows in only one direction.

• AC is commonly used in household appliances and power distribution systems.

• DC is commonly used in batteries and electronic devices.

• Examples of AC sources include generators and power grids.

• Examples of DC sources incl

MPCB stands for Motor Protection Circuit Breaker. It is an electrical device used to protect motors from overloads and short circuits.

• MPCB is designed to automatically disconnect the motor from the power supply in case of an overload or short circuit.

• It helps in preventing damage to the motor and other connected equipment.

• MPCB provides protection against thermal overloads, phase failures, and phase unbalance.

• It is comm...read more

Transformer cooling can be of various types depending on the application and design requirements.

• Transformer cooling can be achieved through methods such as air cooling, oil cooling, and water cooling.

• Air cooling involves the use of fans or natural convection to dissipate heat from the transformer.

• Oil cooling utilizes a transformer oil that circulates through the transformer, absorbing and dissipating heat.

• Water coolin...read more

Power factor is the ratio of real power to apparent power in an electrical circuit.

• Power factor can be calculated by dividing the real power (in watts) by the apparent power (in volt-amperes).

• It is represented as a decimal or a percentage.

• A power factor of 1 indicates a purely resistive load, while a power factor less than 1 indicates a reactive load.

• Power factor can be improved by using power factor correction techniq...read more
