See distance to other cities from Novosibirsk – Novosibirsk – Russia measured in kilometers (km), miles and nautical miles and their local time. Distances are measured using a direct path, as the crow flies and the compass direction is shown as well.
ISOMETER® IRDH275 • Insulation monitoring device for AC and DC IT systems • Application main circuits with connected frequency converters • According to IEC 61557-8 • Automatic adaptation to the system leakage capacitance • Info button to display the device setting The ISOMETER® of the IRDH275 series is designed to monitor the insulation resistance of unearthed main circuits (IT systems) AC, AC / DC 0793 V resp. The AMP Plus measuring principle meets the particular requirements of modern power supplies which often include rectifiers, converters, thyristor-controlled DC drives and directly connected DC components. In these systems often high leakage capacitances against earth occur due to interference suppression measures. Konverter formata doc v latex.
The IRDH275 automatically adapts itself to the existing system conditions. In combination with a coupling device, the Isometers can also be used for higher voltages.
An external supply voltage allows de-energized systems to be monitored too. For door mounting into distribution panels, refer to type IRDH375(B). Do you already know our new product generation.
