Relay is a elctro mechanic or Static or Numerical device
used for
1) protection of elctrical system with CT/PT/thermal unit
etc.
2) control and inter lock
Relay is monitoring the set parameter through
CT/PT/other connected unit like thermal unit and will give
input to connected device when the set parameter cross the
set value.
