PQ Devices

You can integrate the following Power Quality (PQ) device. For more information, refer to the PAC5100/5200/P855 manual.

PAC5100/5200/P850/P855

The multifunctional PAC5100/5200/P850/P855 devices record and process measurands and events according to IEC 61000-4-30 Power Quality (PQ) standard. The devices are used on all voltage levels of power-supply systems. PAC5100/5200/P850/P855 devices are used in 1-phase systems, 3-phase systems, and 4-phase systems (with neutral conductor).

In addition to the measuring function, SENTRON PAC5100/5200 and P850/P855 feature various recorders (e.g. Measurement recorder) to record the measurands in programmable time intervals. Long-term data and events are analyzed and output as report according to power quality standards, for example, EN 50160. The device features a 2- GB memory for data storage.

The input circuits for voltage measurement are galvanically isolated and can be used in IT, TT, and, TN networks. To ensure galvanic separation for current measurements, the lines connected to the current measuring inputs are galvanically separated from the current transformers.
