MeteorSpec-NETWORK - software for designing 0.4kV networks.
MeteorSpec-NETWORK is a CAD plugin for designing electrical part of low-voltage distribution networks. MeteorSpec-NETWORK version 2 provides the following features:
Long-term experience of using the prototype of this program allows to claim that the productivity of electrical designers in the use of this plugin increases several times.
Convenient program interface is built according to all base stages of the design process of the electric part of low-voltage distribution networks. On this page you can see only some of the many dialog windows used by the MeteorSpec-NETWORK.
Assigning data to a power cable. Power cable spans are simulated with lightweight polylines drawn on the program work layer. Certain data must be assigned to an object to define the cable section.
Click on the „Set Construction“ button to select a new cable construction via the "Cable Constructions" window. Having the construction selected, the fields "Cable type" and "Cable wires" load the list of all cables relating to the construction selected.
The dialog window allows to set and view all required data of a power supply source of low-voltage feeder.
A block of a power supply source contains data about the medium-voltage supply network and data about the transformer. Click on the corresponding „Set Data“ button to assign or modify properties of a MV- network and a two-winding transformer.
Generally the loads in outdoor low-voltage distribution networks are „complex" consumers (houses, residential buildings, office buildings etc.).
The dialog window allows to set and view all necessary data of a three phase balanced load. To calculate actual maximum load currents in distribution network feeders you can use the correction factors, such as: factor of maximum utilization and factor of simultaneity.
A block of a junction simulates any node of a distribution network where two or more cable sections are connected together. It may be a distribution panel board, switchboard, connection box, cable joint, cable branch point etc.
Click on the „Set“ button to define internal impedance of the node via the "Junction Internal Impedance" dialog window.
Any junction can be used as a power supply point of street lighting cabinet designed by the MeteorCalc SL software.
The dialog window allows to set the initial parameters to calculate short-circuit currents and voltage losses at the selected point of a feeder. By the user's choice this command allows to perform the following calculations:
Calculation results are output to the window "Results window" for preview or, in a form of a block, output into the drawing.
The calculated maximum short-circuit current (rms and peak values) determines the breaking capacity and the making capacity of circuit breakers and the breaking capacity of fuses. The calculated minimum short-circuit current (rms value) allows to choose the setting of thresholds for overcurrent protective devices and allows to verify disconnection time of protective devices.
The calculated voltage loss helps to choose and check cross-sections of cables. This is a total voltage loss calculated from the power supply source to the node, taking into account all loads of the feeder.
This command calculates the power flow and the load current in the selected cable section. The calculation procedure takes into account correction factors if they are defined for consumers of the calculated feeder.
Calculation results are output to the window "Power Line Calculation" for preview, and are further, in a form of a block, output into the drawing.
The calculated actual maximum load current allows to choose protection devices and check cross-sections of cables.
The build-in Help system describes the operation of MeteorSpec-NETWORK.
