The ISOMETER® is an insulation monitoring device in accordance with IEC 61557-8 for IT systems. The devices are universally applicable in AC, 3(N)AC, AC/DC and DC systems. AC systems may include extensive DC-supplied loads (such as rectifiers, inverters, variable speed drives).
Features
ISOMETER® for IT AC systems with galvanically connected rectifiers or inverters and for IT DC systems (IT = unearthed systems)
Automatic adaptation to the existing system leakage capacitance
Combination of AMPPlus
and other profilespecific measurement methods
Two separately adjustable response value ranges of 1 kΩ…10 MΩ
High-resolution graphical LC display
Connection monitoring (monitoring of the measuring lines)
