WHAT IS RMU AND WHAT IS ITS FUNCTION AND HOW TODISCONNECT
Answer Posted / apu basak
Ring Main Units
Switch the load break switch into EARTH position with an
operation lever. As direct conversion into EARTH position
from ON position is impossible due to its mechanism that it
should be switched first to OFF position before the conversion
into EARTH position.
Only when load break switch is located at EARTH position
doors can be opened or closed.
In case any one of doors is opened, mechanism operation hole
is closed. Thus load break switch operation is impossible,
which means switching to ON position is not allowed
When the works such as replacement of fuse and cable repairs
are finished, all doors of fuse compartment, cable
compartment and cable test facility should be closed before
operation of LBS. The operation order to switch on is EARTH
→ OFF → ON.
Each door is to be pad-locked to avoid unintentional opening
that may cause accident
