Impulse current sensor DRC SD ICS (Part No. 910 935) *

With the optionally available impulse current sensor, impulse currents of up to
100 kA (8/20 µs, 10/350 µs) can be recorded on insulated conductors.
Typical mounting locations are grounding connections of surge protective de-
vices, equipment and lightning protection components.
The sensor must be activated via the web server or the cloud.
Further settings such as the trigger threshold can then also be configured.
Mounting the sensor
The sensor can be attached to the current path to be monitored with two cable ties.
The arrow shows the positive impulse current direction. To avoid influences from
neighboring conductors, the measurement should only be made on individually laid
conductors. Mounting may only be carried out on insulated, non-hazardously active
conductors.
Connection on the device
The sensor is connected to the DEHNrecord SD, Connection I/O:
brown wire > terminal 1 = Imp1
white wire > terminal 2 = Imp2
Maximum stripping of the connection cable: 5 mm
Test and configuration
The connection of the impulse current sensor can be configured via the
internal web server of the DEHNrecord SD or the cloud.
* Variant with impulse current measurement expected to be available from Q4 - 2021
