Answer Posted / vinoth . k
Electrical Interlock- It is the interlocking of two
incoming power supply by using electrical equipments like
relays.
Consider we have two power supply viz, EB and DG supply.If
EB supply cut,DG will run and viceversa.By mistake whether
both EB and DG supply is ON, it will make hazardous action
to our panels.At that time that relay will sense and make
NO,NC changes and allow only one supply pass through our
loads.
Mechanical Interlock- It is the interlock between two power
supply by using Key System.
There are two locks and one key. If we want to switch ON EB
power, first we have to lock DG power and remove the key
from DG lock and then we can switch ON EB supply and
viceversa.
