Roopa Industries Interview Questions and Answers

The question covers slope percentage calculation of kiln, tan value in oil analysis, and material and manpower handling.

• For slope percentage calculation of kiln, we need to measure the height and length of the kiln and use the formula tan(theta) = height/length.

• Tan value in oil analysis is used to determine the acidity of the oil. It is calculated by dividing the acid number by the saponification number.

• Material and ma...read more

Transformer safety relays are devices used to protect transformers from faults and overloads.

• Transformer safety relays monitor the electrical parameters of a transformer, such as current, voltage, and temperature.

• They can trip the transformer offline in case of a fault to prevent damage.

• Some common types of transformer safety relays include overcurrent relays, differential relays, and temperature relays.
