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

A voltage monitoring relay is a device that monitors voltage levels and triggers an alarm or protective action if the voltage exceeds or falls below a set threshold.

• Monitors voltage levels in electrical systems

• Triggers alarm or protective action if voltage exceeds or falls below set threshold

• Used to protect equipment from damage due to voltage fluctuations

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
