^CAMILLE BAUER UNIVERSAL MEASURING UNIT FOR HEAVY CURRENT VARIABLES CONTROLLING ANALYZING METERING

POWER SYSTEM MONITORING THE UNCOMPROMISING MEASUREMENT SOLUTION The universal measurement system of the CAM is designed for a high-precision and disturbance insensitive measurement in multi-phase heavy current systems. The consistent (uninterrupted) measurement records reliably each change in the monitored mains. With its unique combination of hardware and software modules this measuring device provides a solution for each measurement task. The adaption to this task is performed quick and easy by means of the CB-Manager software. Single phase, 2-, 3- and 4-wire systems Strongly distorted networks...

POWER SYSTEM MONITORING LONG-TERM RECORDINGS AND LOGGING The data logger allows to perform long-term recordings of measurement progressions or load profiles, e.g. to monitor the variable load of transformers, feeders or transmission lines. In addition to the recording of mean-values, fluctuations of instantaneous values may be registered to recognize load peaks at the earliest possible moment. By means of the automatical meter reading a time synchronous reading of the meter contents of all devices may be performed, e.g. on a weekly, monthly or three months base. These values can be stored for...

POWER SYSTEM MONITORING VISUALIZATION, ALARM HANDLING AND DATA ANALYSIS MEASUREMENT DISPLAY The display is intended for the visualization of measured data and entries of the alarm, event or operator list. Also state information or measurement information of the I/O interface may be displayed. The user can customize the display almost freely to his individual needs. If necessary a preference display or an automatical sequence of different pages can be defined as well. The navigation is done using the easy to operate keypad. ALARM HANDLING ON-SITE Alarms can be configured to be displayed on-site...

POWER SYSTEM MONITORING CONTROL SYSTEM CONNECTION VIA IEC 61850 (ED. 1) The communication standard IEC 61850 (..Communication networks and systems in substations") is the new standard for substation automation. Each possible device or system function is standardized and mapped in so called logical nodes (LN's). Also the complete communication and the engineering process are stated. So a high grade of independence from manufacturers is achieved. The field of application is situated in switchgears and transformer substations in the medium and high voltage area. The group Metering and Measurement includes...
