3 Description of the ImpulseCheck module
3.1 General description
The ImpulseCheck module is an intelligent assistance system for surge protection in the
field of mains protection. The ImpulseCheck module allows you to measure the state of
health of every single surge protective device (in the following: SPD) via a PROFICLOUD
connection and provides new digital services.
With the ImpulseCheck module as the link between your electrical system and the
PROFICLOUD, the mapping of the status of your SPDs is available worldwide. Via the In-
ternet connection, the status in the PROFICLOUD is continuously updated and visualized
correspondingly.
The ImpulseCheck module detects overvoltage events in your system. Up to four inde-
pendently measuring sensors ascertain the measured data with a high resolution. The as-
certained measured data is buffered in the internal memory and then sent in a compressed
form directly to the PROFICLOUD via an Internet connection. All detected overvoltage
events are permanently stored, evaluated and displayed in the PROFICLOUD.
By means of the aging models of the SPDs stored in the PROFICLOUD, the status of the
SPDs is indicated directly. This way, you always have a current overview of the status of
your connected SPDs. In the PROFICLOUD, you can directly read the status (SPD fully
functional; SPD still functional; replacement recommended; SPD defective; replacement
necessary), act accordingly and take timely action (maintenance, replacement of SPDs).
In addition, the status of the SPDs is also reported back to the ImpulseCheck module. The
status is visualized on the ImpulseCheck module via the four integrated LEDs (CH1, CH2,
CH3 and CH4).
Up to four measuring sensors can be connected to the ImpulseCheck module. When con-
nected correctly, the two-position measuring sensors provide information on high-energy as
well as low-energy pulses from your system. The high-energy and low-energy pulses are
collected and evaluated separately in the ImpulseCheck module. In the PROFICLOUD,
high-energy events are recorded as surge currents, low-energy events as transient over-
voltages.
For the surge currents, the time of the respective event, the technical measured data and
the curve shape are evaluated and displayed.
For the transient overvoltages, the time of the events and the sum of all events that occurred
at the SPD are evaluated and displayed. The detection of transient overvoltage is very sen-
sitive, so that even the smallest events can be captured. The number and frequency allow
for making conclusions about the network quality in your system.
The measuring sensors (up to four) connected to the ImpulseCheck module independently
monitor the live cables directly at the SPD. In a 5-conductor system, e.g., the outer conduc-
tors (L1, L2 and L3) and the neutral conductor (N) can be monitored by means of one sensor
each. The ImpulseCheck module and the PROFICLOUD ascertain and display the resulting
current in the PE path.
For this, the hardware must be configured accordingly in the PROFICLOUD after installa-
tion. Only then will you receive a meaningful evaluation of the statuses of the SPDs con-
nected to the ImpulseCheck module.
