An army of alert sentinels
A full range of fault indicators for fast and selective fault location in MV secondary distribution system.

• Detecton of faults between phases producing a current exceeding the threshold and earth faults both on insulated neutral networks and on compensated neutral networks, without any need of changing the settings between different confi gurations and regardless of the feeding direction.
• Compliant with several utility technical specifications.
• Measured acquired by the CTs, capacitive voltage dividers or electronic sensors.
• 4...20 mA current converter output of  for sending the phase current measurement to the remote control terminal.
• Little maintenance.
