The high reliability of IT systems is
ensured by continuous insulation monitoring. Insulation monitoring detects developing insulation faults and
immediately reports that the value has fallen below the minimum. This prevents interruption of operation
due to a second, more serious insulation fault.
ABB developed a completely new range of insulation monitoring devices for AC, DC or AC/DC
IT systems up to 690 V AC or 1000 V DC. Most standard applications can
be served with just 4 devices. In addition, a version for solar applications with increased leakage capacity has been
added.
