Q1. Use of shunt relay in acb.
Ans. 
A shunt relay in an ACB is used to provide protection against overcurrents by diverting excess current away from the main circuit.
• Shunt relay is connected in parallel with the main circuit of the ACB.

• It detects overcurrents and activates to divert the excess current through a shunt path.

• This helps in protecting the main circuit from damage due to overcurrents.

• Shunt relays are commonly used in Air Circuit Breakers (ACBs...read more

Q5. Working principle of wtp plant.
Ans. 
WTP plant works on the principle of physical and chemical processes to remove impurities from water.
• Water enters the plant and goes through processes like coagulation, flocculation, sedimentation, filtration, and disinfection.

• Coagulation involves adding chemicals to water to make impurities clump together.

• Flocculation helps in forming larger particles called floc for easier removal.

• Sedimentation allows the floc to sett...read more
