2 types of dewe 838 pna
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
p q parameters
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

a pplications
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
i nstallation
Installation
  • Fix installed instrument
    • DIN Rail
    • Wall Mount
    • Counter Panel
s oftware
Software
  • WEB Browser Interface
    • for Control
    • Configuration
    • and Online monitoring
t ime synch
Time synch
  • Time Synchronisation
    • Offline with web interface
    • Online with time Server
      • NTP
d ata handling
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

mli i d with usb stick
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
slide11
Postprocessing:

with the Report Generator PMT

the r eporting software for all this
The Reporting Software for all this:
  • Diagrams
  • FFT
  • Faults
  • Events and statistics
  • Alarms
  • Topology
  • Single instruments and systems
  • Multi user interface
  • Report Generator
d iagrams
Diagrams
  • Diagrams
    • Also for more scales on one screen
  • Statistics table
    • Avg/min/max
    • Quantil values
    • Markers and difference
    • ….
diagrams h istogram
Diagrams - Histogram
  • Histogram inclusive
  • Settings for the statistic on own needs
slide16
FFT
  • Bar Chart for one or more values
  • Limits (free configurable)
    • Example: EN50160, IEC61000-4-2
  • Statistic with limits
  • Up to 50 harmonics
t ransients list
Transients List
  • List of faults
  • Auto refresh
  • „Confirm“ function
  • Instruments / group filters
