SEK-3 establishes a monitored equipotential bonding of very low resistance between ship and pier which counteracts the physical effect of electrical potential difference. This explosion protection measure prevents uncontrolled sparking when handling conductive elements at the terminal. In addition, the SEK-3 signals unsafe situations (such as over-voltage or over-current caused by active sources) by flashing LEDs and switching off the corresponding control outputs.
