Power fault recorder
Dewetron
The DEWE-838-PNA series is designed for fault and plain power quality monitoring in transformer stations or on counter panels and can be implemented in global Power Monitoring Systems. The relevant standards, especially IEC 61000-4-30 class A are supported and highly accurate voltage inputs allow accuracies < 0.1 % on the fundamental.
- 838-PNA-V with 3 voltage inputs for RMS of the voltage, harmonics, flicker, asymmetry and frequency
- 838-PNA-P with 4 voltage and 4 current inputs, combines all functions of the voltage version (DEWE-838-PNA-V) with a full equipped power meter (active power, reactive power, power factor and many more)
- 838-PNA-W with 3 voltage and 3 current inputs and inputs for wind direction and speed specially for wind turbines
- high EMC protection up to 4 kV
- data transmission via Ethernet or USB device
- data storage on central SQL-databases possible
- 16 bit resolution
- 10kS/s sampling rate
- harmonic and and inharmonic overtone, flicker
- remote controllable
- mountable on DIN-rail, counter panels or wall
