In certain specialized installations, the electrical network is designed so that the first earth fault does not cause an immediate disconnection.
Why is insulation monitoring needed
A special device continuously monitors insulation resistance and alerts when a fault occurs.
Where it is used
In applications where continuity of service is critical and is provided for by the network design.
