Circuits
A circuit can exist of:
· a single 3-core cable
· three 1-core cables
New circuits can be added using the menu New | Circuit.
Because of the IEC 60287 standard, it is not always possible to calculate more than one circuit:
Under ground:
No drying of ground
Partial drying of ground
Prevent drying of ground
Multiple circuits possible
One circuit only
Multiple circuits possible
In air:
No solar radiation
Solar radiation

Configurations from standard
In the dialog used to add a circuit, certain properties can be set. These are:
· cable type 21
· lay 22
· current 25
· duct 26
· trough 27
A circuit can also be given a name and a circuit number.
The same dialog is also using to change a circuit.
4.3.2.1
Cable type
On this tab a specific cable type can be chosen. A filter can be used to narrow down the selection of cables from the
cable type database. Filters can be used with 3 criteria:
· isolation (plastic or no plastic)
· number of cores (1 or 3)
· voltage level
Filter for the voltage level:
The voltage levels are line voltages, however, in the cable type database, the phase voltage is stored.
Some PILC cables have a higher phase voltage (8/10 and 10/10 kV), so these cables will be in a higher voltage
range.
If a cable type is chosen, a graphical representation of the cable is automatically shown.
The maximum allowed conductor temperature of the chosen cable can be adjusted if necessary.
