HBL’s ELM in DC power systems enables quick detection of earth faults to prompt for corrective action. It works on the principle of residual or differential magnetising current induced in a current transformer. ELM is used in DC power systems like battery chargers, AC-DC converter systems, DC-DC converter systems and DCDBs. It provides the customer an ability to install immunized earth leakage protection systems in their installations.
