Electric cable current rating can easily

be found in manufacturers brochures

for standard confi gurations. For some

deviations, derating factors can be found

for an approximation. But often the

tables are not applicable or do not satisfy

the questions of the modern engineer.

And for dynamic calculations he’ll need

dedicated software.

Vision Cable Analysis calculates the

current rating for all single and three

phase cables, installed in free air and

buried, in both simple and complex

situations.

Vision Cable Analysis is easy to learn and

allows the user to effi ciently approach

Vision Cable Analysis is a practical computer program for calculation of the electric current rating of cables. The cal-culation method is based on both the IEC 60287 and the IEC 60853 standards. Thanks to the logical and user-friendly user interface the computer program is very easy to learn.

Phase to Phase

Phase to Phase focuses on software development

for transmission and distribution network analy-

sis. The vision is to introduce and enhance the

network analysis for a broad range of engineers

by means of innovative products.

The fulfi lment of this vision is supported by the

growing sense of cost in planning, development

and management of the electrical infrastructure.

The products are used by electricity companies,

industry and consultants for network develop-

ment and analysis.

IEC 60853

The IEC 60853 standard describes the

methods for calculation of the cyclic

cable rating and the emergency cable

rating.

The dynamic cable rating calculation

is based on the fact that a cable, not

conducting 100 % of the maximum

continuous current, has not reached its

maximum temperature. Thanks to the

dynamic properties of cable and soil, the

temperatures respond slowly to a step

change in current, enabling the operator

to overload the cable during a short time

in emergency situations.

Vision Cable Analysis calculates:

• Cyclic rating (7 daily 24-hour cycles)

• Emergency rating

• Step response

These calculations show how much

more than the continuous current rating

the cables can conduct in case of a cyclic

varying load. The cyclic rating depends

on the shape of the daily load cycle.

These calculations also show how many

extra loads can be added to the cable

in case of emergencies. The emergency

current rating strongly depends on the

starting temperature and the emergency

duration.

IEC 60287

The IEC 60287 standard describes the

calculation of cable losses and thermal

resistances for the cable and its environ-

ment.

Functionality

Vision Cable Analysis calculates:

• Maximum current rating for multiple

circuits of single and three core cables

• Temperatures of all cables for specifi ed

currents

• Temperature of the surrounding soil

• Sensitivity analysis

All results are graphically presented on

the screen. The result of any change is

presented immediately.

Cable types

The starting point for the calculation

is always the cable construction. Vision

Cable Analysis supports calculation of all

commonly used single core and three

core cable types of standard isolation

materials and construction, like XLPE,

PVC, Oil pressure, mass impregnated

and pipe-type cables.

For all cable types, properties, specifying

type and construction, can be viewed

and edited in a graphical Cable Edi-

tor. Using this Cable Editor the cable

database can easily be modifi ed and

extended.

Confi guration

The ampacity can be calculated for

cables installed in free air and for buried

cables. Vision Cable Analysis enables the

user to input and manipulate the con-

fi guration of all cable circuits graphically.

Calculation

For buried cables, depth and relative

positions to each other are important

factors. Additionally, heat sources, by

specifi cation of either temperature or

heat production, are easily applicable.

Vision Cable Analysis calculates the cable

current rating for the situations where:

• no drying-out of the soil occurs,

• partial drying-out of the soil occurs

(two-zone approximate physical

model) and

• drying-out of the soil is to be avoided.
