Earth Leakage Monitors

Undiagnosed faults in the electricity supply can produce very high economic losses. Monitoring and signaling of unwanted earth faults helps the utility minimize outages.

HBL’s ELM in DC power systems enables quick detection of earth faults and prompts the operator to take corrective action. It works on the principle of residual or differential magnetising current induced in a current transformer. Our ELM is used in DC power systems such as battery chargers, AC-DC converter systems, DC-DC converter systems and DC Distribution Boards. It provides the customer an ability to install earth leakage protection systems in their installations at a reasonable cost.
