CTUM 15 is a alstom make electromechanical relay used for the Sensitive earth fault protection for feeders by means of a CBCT. These operate on the principle of leakage current measurement by means of a residual connection of CT or a CBCT. These can be set for 1% to 16 % of CT ratings. The time dial settings can be set from 60 milliseconds to 750 miliseconds. These provide protection against high resistance ground faults on an earthed system.
