Applications
The SICAM P850 device is used in single-phase as well as in three-wire and four-wire systems (with neutral conductor). The device is applied wherever comprehensive measurement of supply quality is necessary - at power utilities as well as in industry and trade sectors.
Power Quality
Ensuring power quality in a phase of energy transition
Increasing power feed-in from renewable resources poses new challenges for municipalities and distribution system operators.
The stable supply of electric power is any grid operator's top priority. To avoid fluctuations in power quality and prevent disturbances, grid monitoring, control, and automation systems need to be adapted and optimized across all voltage levels.
Customer benefit
- Comprehensive acquisition of relevant network parameters
- Easy operation via integrated web server for parameterization, diagnosis, evaluation and reporting
- Manufacturer-independent, comparable measured values obtained by using the IEC 61000-4-30 standard measurement methods
- Interoper ability is guaranteed by using standard interfaces and standard protocols (IEC 61850, Modbus, IEC 60870-5-103)
