Hetero Interview Questions and Answers

Various types of circuit breakers are used in electrical engineering, including MCB, MCCB, and ACB for different applications.

• MCB (Miniature Circuit Breaker) - Protects against overloads and short circuits in residential applications.

• MCCB (Molded Case Circuit Breaker) - Suitable for industrial applications, handling higher current ratings.

• ACB (Air Circuit Breaker) - Used for high voltage applications, providing pr...read more

The transformer primary load refers to the electrical demand placed on the primary winding of a transformer.

• The primary load is determined by the connected devices on the secondary side.

• For example, if a transformer supplies power to a motor, the motor's power requirement defines the primary load.

• The primary load affects the current flowing through the primary winding and the voltage drop across it.

• Understanding p...read more

I led a deviation investigation on a quality control failure in a manufacturing process, ensuring compliance and corrective actions.

• Identified the deviation during routine quality checks, where a batch failed to meet specifications.

• Conducted root cause analysis using the 5 Whys technique, revealing a malfunction in the calibration of equipment.

• Collaborated with cross-functional teams, including production and qual...read more

Change control is a systematic approach to managing changes in a project or process to minimize disruption and ensure quality.

• Identify the change: Recognize the need for change, such as a new requirement or a problem that needs addressing.

• Document the change: Create a change request form detailing the nature of the change, its impact, and the rationale behind it.

• Review and assess: Evaluate the change request by st...read more

Indicators in analysis help assess performance, trends, and outcomes across various fields, guiding decision-making processes.

• Key Performance Indicators (KPIs): Metrics like sales growth, customer satisfaction, and employee turnover.

• Financial Ratios: Examples include liquidity ratios, profitability ratios, and debt-to-equity ratios.

• Statistical Indicators: Mean, median, mode, and standard deviation used in data ana...read more

Dipole antennas typically have an input impedance of around 73 ohms in free space.

• The input impedance of a half-wave dipole antenna is approximately 73 ohms.

• In practice, the impedance can vary based on the surrounding environment and feed point.

• For a center-fed dipole, the impedance is higher than at the ends.

• Impedance matching is crucial for efficient power transfer; using a balun can help.

• Example: A dipole anten...read more
