Woosun Electrics Interview Questions, Process, and Tips

The number of turns in the primary coil

• The number of turns in the primary coil remains constant

• The voltage-frequency ratio is constant

• The power input and output are not equal due to losses

• The transformer efficiency can change based on load

Efficiency of a transformer is maximum when the copper losses are equal to iron losses.

• Efficiency is maximum when the transformer is operating at its full load capacity.

• Copper losses are caused by the resistance of the wire used in the transformer's windings.

• Iron losses are caused by the magnetic properties of the transformer's core.

• Efficiency can be improved by using high-quality materials and reducing the air gap bet...read more

Transformer ratings are usually expressed in terms of voltage, current, and power.

• Voltage rating

• Current rating

• Power rating

• kVA rating

• Frequency rating

RA stands for Risk Assessment, which is a process of identifying hazards and evaluating the associated risks to determine appropriate control measures.

• RA involves identifying potential hazards in the workplace or environment.

• It includes assessing the likelihood and severity of harm that could result from each hazard.

• RA helps in determining the level of risk and prioritizing control measures to reduce or eliminate the r...read more

CAPA stands for Corrective and Preventive Actions. It is a systematic approach to identifying and addressing the root causes of problems or non-conformities.

• CAPA is a key element of quality management systems in various industries, including manufacturing, healthcare, and pharmaceuticals.

• Corrective actions are taken to address existing issues or non-conformities, while preventive actions are implemented to prevent pote...read more
