Via eypad the user can e.g. acnowedge aarms or reset extreme vaues. The parametrization of the graphic dispay and the assembing of user specifi c measurement dispays is performed using the CB- Manager software. Parameters ie contrast or the seection of the dispay anguage (Engish, German, French, Czech, Spanish, Dutch, Itaian) can be set aso directy using the eypad. The operation of the graphic dispay is described in a separate document, which is attached in Engish and German to a devices equipped with dispay. The appropriate manuas for a anguages may be found on the provided software CD. Rogowsi current inputs (optiona) See appendix A ogger and ists (optiona) By means of these options measurement and event data may be ong-term recorded. Depending on the appication 9 different inds of data may be acquisited: Progression of mean-vaues with interva time t1 (1s 60 min) Progression of mean-vaues with interva time t (1s 60 min) Min/Max vaues during interva t3 (1s 3h) Meter readings ist entries of aarms ist entries of events ist entries of system messages They share the avaiabe storage space of 64Mb size. The memory aocation may be performed using the CB-Manager software. Due to the high degree of freedom for the confi guration of ogger and ists no genera information about the maxima storage duration can be given. But these can be seen in the software when seecting the memory aocation, the measurands to store and the number of ist entries. The reading and anayzing of ogger and ist data can be done using the CB-Anayzer software. Ethernet with Modbus/TCP protoco (optiona) Ethernet provides a transmission medium with high bandwidth for anayzing measured data in rea-time. CAM supports the protocos Modbus/TCP and TP. Modbus/TCP is a common used standard which is supported by a arge number of visuaization software toos and thus aows a fast impementation of the device. Via the Modbus/TCP interface a functions are supported, which are possibe using the Modbus/RT or SB interface. 6 Data sheet CAM e 0.14 Camie Bauer

7 SIEAX CAM niversa measuring unit for heavy current variabes For the time synchronization of devices via Ethernet, TP (etwor Time Protoco) is the standard. Respective time servers are used in computer networs and are at free disposa via Internet as we. By means of TP a devices can be used with a common time base. Appications Test stands for aggregates: Recording of the dynamic behaviour of motors and generators. Remote monitoring and acquisition of power distribution systems via Intranet / Internet. Recording of the dynamic oading of energy suppy systems. IEC support (optiona) The communication standard IEC ( Communication networs and systems in substations ) is the new standard for substation automation. The CAM with IEC support is a measuring device which bases on the appication of conventiona current and votage transformers. Therefore it is most suitabe for the modemization of substations, not touching the aready instaed conventiona transformers. It provides the foowing ogica nodes: MMX / MMX: Instantaneous vaues of votages, currents, frequency, power quantities and oad factors as we as their maximum and minimum vaues. MHAI / MHA: Individua harmonics for votage and current, THD (tota harmonic distortion) and TDD (tota demand distortion) and their maximum vaues. MMTR: Active and reactive energy meters for incoming and outgoing power. One instance for both high and ow tariff. MSTA: Mean vaues of votage, current, active, reactive and apparent power as we as their maximum and minimum vaues on instantaneous vaues base. A measured within the same interva. These vaues are provided for each phase as we. MSQI: Imbaance of votage and current, cacuated in accordance with two different methods. GGIO: Maps the information of assembed anaog and digita input modues. So CAM may be used as an IEC gateway. By means of GGIO instances state information (e.g. O/OFF or a sefmonitoring signa), anaog measurements (e.g. a temperature) or metering puses (Wh / VArh) of non IEC capabe externa devices can be handed. These measurement data then can be accessed via the IEC interface. CB-Manager Software The PC software CB-Manager which is suppied with each device may be used for the parametrization of the SIEAX CAM. Via SB, RS485 or Ethernet interface a measured data can be read and recorded as we. The access to the device can be restricted by activating a password protection system.

11 SIEAX CAM niversa measuring unit for heavy current variabes Appendix A Version with Rogowsi current inputs This version provides instead of current inputs votage inputs for connecting the integrator circuit of f exibe Rogowsi cois. Rogowsi cois can be fi tted quicy and easiy without opening the current circuit and can cover a wide current range using switchabe ranges. They can transform fast-changing currents and harmonics much better than conventiona current transformers. Thus this version is suited for appications where an accurate anaysis of harmonics respectivey the corresponding system feedbac is required, for monitoring fast changing current f ows and for test faciities, where the device under test must be repaced often and quicy. To aow an appication in industria environment, the power suppy of the integrator of the Rogowsi cois can be performed directy via the CAM. Because not a cois use the same power suppy, different hardware version (3V, 4.5V, 6V und 9V) are offered. The inputs for connecting the Rogowsi cois are designed for 5V and measure up to a maximum of 10V without restriction. Rogowsi cois normay can be used for mutipe current ranges, where for a present nomina current input aways the same votage output, normay 3V, resuts. The switchover of the current measurement range is performed via the rotary-switch on the integrator. The confi guration of the CAM for the same current range has to be done separatey by means of the CB- Manager software.
