4. Preparation of the measurement application 4.1 Connecting to the measurement device 4.1.1 Connection via LAN interface Before devices can be connected to an existing Ethernet network, you have to ensure that they will not disturb the normal network service. The rule is: None of the devices to connect is allowed to have the same IPv4/6 address than another device already installed This also applies if the network only consists of a PC and the measuring device.
Page 9
Network settings (Communication | Ethernet) The following settings have to be arranged with the network administrator: Must be unique, i.e. may be assigned in the network only once • IPv4/6: IP address Defines how many devices are directly addressable in the IPv4 network. This •...

Time synchronization via NTP protocol For the time synchronization of devices via Ethernet NTP (Network Time Protocol) is the standard. Corresponding time servers are used in computer networks, but are also available for free via Internet. Using NTP it's possible to hold all devices on a common time base. Two different NTP servers may be defined.
Communication tests Via the service menu on the device website you may check if the selected network structure is valid. The device must be able to reach the DNS server via gateway. The DNS server then allows resolving the URL of the NTP server to an IP address.
4.1.3 Resetting the network settings If the communication settings of the communication interface are no longer known or an activated whitelist prevents access to the device, they can be reset to the default settings via the keys on the device.

Before HTTPS communication can be used a root certificate needs to be installed. The user can either use a Camille Bauer certificate (default setting) or its own customer certificate. This may be changed when defining the Settings of the Security system.
The imported certificate is valid for all devices of the PQ, AM, DM and CU series. Agree to install the certificate if the below security warning appears: Customer certificate You may also use a customer server certificate with a private key, but for that you first need to change the Settings of the Security system in the item Web Security.
Page 22
Example of a security log: The severity of each message is shown in a color code, which may also serve as filter criteria. Each entry into this list may, if activated, also be transferred to a central log-server using the SYSLOG protocol for security auditing.
4.4 PQ monitoring Power quality monitoring provides both a statistical evaluation, allowing an assessment of compliance with standards (e.g. EN 50160) or supply contracts, as well as records of events in the grid (e.g. power voltage dips). This facilitates the analysis of causes and effects. Conformity reports may also be created directly via the website of the device.
Mains signalling voltage The device monitors mains signalling voltages, which are transmitted in the supply system for control purposes, and records them as events (8.1.3). Typically, these are ripple control signals. The user can define the frequency of the signalling voltage, the threshold and hysteresis (related to the nominal voltage) as well as the recording duration in multiples of the measurement interval of 10/12 cycles.
The assessment of the PQ statistic is shown in the chapter Data recording | PQ statistic (8.1.4), including the creation of conformity reports. Recorded PQ parameter groups Measurement Averaging time Applied limits Power frequency 10 s Voltage magnitude 10 min. The applied limits and time conditions of the preset standards can be seen via the device Flicker P...

6.3 Current connection Current Link The Current Link supports the current measurement of up to 9 feeders with up to 36 current channels. It consists of Current Modules, which are arranged in a ring structure and monitor 3 or 4 channel feeders. A typical connection of a PN-Moduls is shown below: Rogowski coils The Rogowski coils of the current modules are different in color and also marked: Brown –...
Page 31
The individual current modules in the ring are connected using SMA connection cables. The SMA connection cables must not be kinked during assembly, as the conductors could be damaged. The bending radius should be not smaller than 50mm. The fastening of the SMA cables to the corresponding connectors should be done with a torque wrench with a maximum torque of 1 Nm.
The junction box of a current module must not be mounted on bare conductors, nor must connecting cables be routed over bare live conductors. If there are bare connections or busbars in the immediate vicinity, the junction box and connecting cables must be secured in such a way that their metal parts cannot touch live, bare parts in the event that the fixing of the junction box or a connecting cable becomes detached unexpectedly.
6.5 GPS time synchronization The optional GPS connection module serves for connecting a GPS receiver as a very accurate time synchronization source for the measurement device. Time synchronization via NTP or GPS is an elementary requirement for class A power quality measuring devices.
Connecting the GPS receiver Never connect the RJ45 socket of the connecting cable directly to a network device such as a router or switch. These devices could be damaged. The GPS receiver is plugged directly into the GPS connection module. The connection cable has a length of 5 m.

7.3 Measurement data reset The device can store data of up to 20 measurement locations. If measurement locations are replaced, i.e. new configurations are loaded into the device, data belonging to the old configurationen can no longer be evaluated correctly and should therefore be deleted. However, data cannot be deleted for individual configurations, only as a whole.
7.4 Start / stop data recording The data recording can be started or stopped directly at the device or via the device website. There is a delay when starting and stopping data recording until this state change completes. During this delay the local LED associated to the RECORD button flashes and a corresponding status window is displayed via device website.
8. Evaluation of recorded data For the evaluation of recorded data, you first have to activate the configuration used during data recording. Only data recorded with the active configuration will then be visible and can be assessed. ATTENTION: If the configuration used during data recording has been changed or is no longer available, an evaluation of the data may no longer be possible.
Data export as CSV file In some data visualizations an export as CSV file (Comma Separated Value) can be made. For time-sequences of measurements (e.g. meter contents) the time range of the data to export can be selected. For event lists the last 250 events are stored.

8.2 Measurement information in file form Measurement information can also be provided in file form. The data export scheduler is used for this purpose, with which various predefined tasks can be managed. The files can be generated periodically or event-driven and stored locally in the device and/or sent to an SFTP server. Managing and customizing tasks for providing files is done via the menu Data export | Data export scheduler in the settings menu.
Periodic PQDIF If this task is activated, the device periodically creates shortly after midnight PQDIF files and saves the file or files in a hierarchical time structure (year, month, day). By selecting a predefined task, the associated settings can be adapted. justed by selecting the entry. For example, for the task Periodic PQDIF you may choose whether the information should be stored in one file or in up to three files (statistics, histograms, events).
The existing file structure is displayed in a new tab. All files are stored in a hierarchical time structure (year, month, day). By selecting the desired date and double-clicking on the appropriate file, a PQDIF may be easily downloaded. 8.2.3 Download of PQIS files The files stored in the device can be downloaded and then transferred to the PQIS software.
8.2.4 Periodical sending to a SFTP Server If in the data export scheduler the sending to an SFTP server was selected as action, the appropriate files will be sent periodically to the SFTP server defined in the settings of the communication. For improving security, you may select that the device connects to trusted hosts only.
