Transformer logger and Monitor - Network wide access platforms

SYDNEY - Oct. 24, 2017 - PRLog -- To achieve reliable and secure supply, network engineers need to know how transformers are performing and when/ where proactive action should be taken. The Miro-F provides
engineers with information for: planning; operations; maintenance; and network modelling. Information includes V, I, P.F, THD, Sags, Swells, Interruptions and other power quality measurements.
A typical Australian utility will have thousands of distribution transformers in its network with a mix of pole-tops and kiosks which can vary in capacity, typically ranging in size from 15kVA to 1,500kVA. The Miro-F provides access platforms intended for secure monitoring of large scale networks; hence ideally suited for Australian networks.

NETWORK WIDE ACCESS PLATFORMS
The following provides a brief description of the various access platforms offered by the Miro-F. All the access platforms described below are supported via I P over 3G/4G Cellular and Ethernet networks.
periodically to the FTP server, to be viewed and analysed by Citrus. This system features: periodic push of data; and Security(FTPES - FTP with explicit TLS).

Citrus Data Retrieval CIDR):
CiDR is an automatic data collection service that is installed on a server and polls Miro-F devices to retrieve data. System features: Time synchronisation (server); Pulls data periodically (server initiates connection);
Configurable download period; Automatic conversion to PQDIF; and Security (SSH encryption & authentication).

SCADA - DNP3.0:
Analogue and binary data points from the Miro-F device are polled periodically by the SCADA master and stored in a database, ready for interrogation and analysis. System features: Time synchronization (SCADA Master); Analogue dead-bands; Automatic reconnection; and Security (DNP3.0 Secure Authentication).
Examples of analogue data points include:
Voltage (L-N, L-L), Current (L-N, L-L), Harmonic magnitudes, Downloads of logged data; Firmware updates; and Security (SSH THD, Flicker (Pst, Plt), Power (W, Var, VA), Power Factor, encryption & authentication). Temperature, Voltage (min, max), Current (min, max), Voltage (10 cycle rms), Current (10 cycle rms).
Examples of binary data points
include: IEC defined events (Dip, Swell, Interruption) and single-individual Miro-F devices initiate an FTP Upload connection to phase outage.

Automatic FTP uploads:
Individual Miro-F devices initiate an FTP upload connection to a server. Full power quality data including event captures are pushed perdiocially to the FTP server, to be viewed and analysed by Citrus. This system features periodic push of data and security(FTPES-FTP) with explicit TLS).

Manual TCP/IP.
A connection is made to each Miro-F using a TCP/IP connection (as provided by citrus software platform).
Inserting a static IP address provides a transparent connection which allows configuration,downloads of logged data, firmware upgrades and security encryption and authentication.
