Fault32 - For Windows XP / Vista & 7.0Calculation of Network Currents and Voltages under Fault conditions
A powerful easy to use tool for determining fault currents magnitudes, the distribution of fault currents in a network, and corresponding network voltages.
Calculates the standard balanced and unbalanced faults, with the option of including the effect of fault impedance on the fault currents.
Used by engineers and technical personnel responsible for planning, design, operation and protection of electric power networks.
Use Fault32 for analysing the following types of power system faults in both radial and fully meshed networks:
Ideal Training Tool
Fault32 is available is ideal for training design, protection & operating personnel,technicians and undergraduates
who need to understand how a power network performs under fault conditions.
• Node/Bus or line faults can be applied
• Line faults can be located from 5% to 95% along the length of the line
• Option to set breaker open condition with line faults
• Optional fault impedances
• User selected option to work with Feeder and Grounding impedance in ohms per unit
• Optional automatic conversion of existing data when Feeder & Grounding Impedance option is changed from ohm to per unit, or vice versa. This allows data to be entered in either units as required.
• Extensive support for data entry and calculations conforming to requirements of Australian standard AS3851 "The calculation of short circuit currents in three phase a.c. systems
• Calculations validated against standard text book examples and AS3851. Files provided for user verification
• Handles transformer phase shifts for various start and delta winding combinations
• 3-winding transformers directly supported with data entry based on "Nameplate details"
• Results available in Phase or Sequence values(i.e Phase A, B & C or Positive, Negative & Zero sequence)
• Fault currents reported in kA, MVA and per unit of system base
• Quick and easy "switching" (i.e setting status) of network component to be IN or OUT of service
• All data files needed can be created and edited within Fault32 or can be sourced externally - for example, from Datashares' "ViewNet" (Database of network Impedance and Network connectivity) software or, in some circumstances, data can be accessed from external databases, GIS systems etc. (Details on accessing external data sources available on request)
• Feeder to store and retrieve common line/cable impedance data. Data stored in ohm/unit length and automatically converted to user selected units for Line/Feeder data, i.e ohms per unit
• Transformer database to store and retrieve impedance data. Any transformers details available in the Transformer details available in the Transformer data editor in Fault32 can be directly added to the transformer database
• Database categories can be defined to group entries and simplify descriptions and selection
• Copy and Paste to duplicate any network component (ie Node/Bus, Source, Transformer, Line/Feeder)
• Tool-bars for quick access to all main functions in the program
• Context (Right mouse button) menus when in data editors for easy access to editor functions
• Extensible data validity checking
• Data is compatible with Datashares' PowSys32 and Relcord32
• Network wide reports, or reports based on area & zone identification, as well as the Bus/Node list (a user selected list of nodes)
• Graphical and tabular presentation of results
• Reports can be directed to Screen, Printer or File
• Reports to file are ASCII text files able to be imported into spreadsheets for further processing, graphing, word processors for inclusion in report documents
