Description - SICAM P855

The SICAM P855 multifunctional device is used to collect, display measured electrical variables such as AC current, AC voltage, power types, harmonics, etc. The measurands and events are collected and processed according to the Power Quality Standard IEC 61000-4-30. The communications interfaces can be used to output the measurands to a PC and the control center or display them on a display. In addition to the monitoring function, the SICAM P855 all-in-one device also provides a combined recording and evaluation function. It can record measurands at programmable time intervals, using a wide range of recorders, such as power quality and fault recorders. Long-term data and events are evaluated directly in the device according to the power quality standards (such as EN 50160) and output as reports.

Key features

• Robust and compact design according to IEC 62586-1, Class S (leading standard)
• Use of SICAM P850 / P855 in the IT, TT and TN power systems
