  1. DEWE-838-PNA Series

  2. 2 Types of DEWE-838-PNA • DEWE-838-PNA-V • 3 Voltages (1400V max) • PQ Parameters • IEC 61000-4-30 Class A • DEWE-838-PNA-P • 4 Voltages, 4 Currents (5A direct) • PQ Parameters + POWER Calculation

  3. PQ Parameters • Frequency • Voltage RMS • Flicker • Harmonics • Unbalance • Voltage Variations (DIPs, Faults) • Rapid voltage changes • Signal voltages IEC 61000-4-30 Class A EN 50160

  4. Applications • LV Grid • PQ Monitoring at customers • PQ Grid monitoring for statistical applications • MV Grid • Transformer stations • Industrial customers • HV Grid • Single lines • Large customers

  5. Installation • Fix installed instrument • DIN Rail • Wall Mount • Counter Panel

  6. Software • WEB Browser Interface • for Control • Configuration • and Online monitoring

  7. Time synch • Time Synchronisation • Offline with web interface • Online with time Server • NTP

  8. Data Handling • MS SQL based System • Data download a) Manual = offline mode (Directly with Software) b) Automatic = online mode (Ethernet to SQL Server) • Postprocessing • PMT • Memory • 512 MB on board • 2 GB SD Card a) manual b) automatic MS SQL Server Postprocessing = PMT

  9. MLI = ID with USB Stick • MLI = Measurement Location Identification • Identification with USB Stick • USB Stick has information about settings and location • In case of replacement the new instrument starts as the old was • Network and database connections stay the same

  10. Combination with 818 PFR Systemsand portable PNA instruments 230 V (400 V) 20kV (or 30kV) 110kV 380kV

  11. Postprocessing: with the Report Generator PMT

  12. Report Generator - PMT

  13. The Reporting Software for all this: • Diagrams • FFT • Faults • Events and statistics • Alarms • Topology • Single instruments and systems • Multi user interface • Report Generator

  14. Diagrams • Diagrams • Also for more scales on one screen • Statistics table • Avg/min/max • Quantil values • Markers and difference • ….

  15. Diagrams - Histogram • Histogram inclusive • Settings for the statistic on own needs

  16. FFT • Bar Chart for one or more values • Limits (free configurable) • Example: EN50160, IEC61000-4-2 • Statistic with limits • Up to 50 harmonics

  17. Transients List • List of faults • Auto refresh • „Confirm“ function • Instruments / group filters

  18. Fault Diagrams • Waveform recording (seconds) • RMS recording (minutes)

  19. Events and statistics • Eventlist • Events in detail • DIS DIP IEC 61000-2-8 • CBEMA / ITIC • SEM F47 • IEC 62040 USV Class 1

  20. Events and statistics - Eventlist

  21. Events and statistics - Details

  22. Events and statistics - DIS DIP

  23. ITIC, SEMI F47 etc… Full flexibility for your DISDIP Graphs ! ITIC (CBEMA) curve UPS IEC 62040 Class1 Semi conductor standard SEMI F47

  24. Topology • Geographic view • Status of recorders • Faults and alarms

  25. Report Generator • One Report per diagram • Multiple different diagrams in one large report

  26. General Features • For single instruments (PNA 838 etc...) • And for systems (PFR 818 etc…) • User / group: security management • Automatic update of software • Assistents for setting up of diagrams • Multi diagram interface • Multi language support • based on MS SQL Server
