Using residual current monitoring allows changes in the level of insulation to be detected at an early stage before protective devices are tripped by a high residual current, that puts people at risk and involves the risk of fire.
This time advantage allows countermeasures to be planned and contributes to the high availability of the power supply and therefore the system. Thanks to the BACHMANN BlueNet PDU, this residual current monitoring isn't just undertaken at central measuring points, but on the socket outlets of every consumer. This standard-compliant residual current technology, the result of a joint development with Bender, provides a high physical granularity, maximum safety and high availability. This AC / DC sensitive technology monitors all kinds of residual current in modern power supplies with switching power supplies. The new BlueNet residual current PDU is therefore particularly suited to use in IT.
Permanent monitoring is absolutely essential in modern information technology. Continuous monitoring equipment reduces the work involved in statutory repeat testing. In accordance with accident prevention guidelines (BGV A3), the test dates for measuring insulation can be adapted to suit actual circumstances and optimise costs using permanent RCM.
The BlueNet residual current monitor is able to record residual currents of 5 mA and higher. Residual current activation values can be set in the BlueNet software. BlueNet software reliably signals instances where these values are exceeded. All measured values are transferred to superordinate monitoring systems via the Ethernet interface. A local display in the PDU also provides information about all important measured values.
This setup ensures that the availability of the power supply has absolute priority at all times and that the system is not unexpectedly cut off in the event of errors.
The BlueNet technology also allows a master-slave network to be installed, saving installation costs and minimising the administration work involved.
