Use of the breaking capacity of previous protections

Section 434.5.1 of the UNE-HD 60634-4-43 code allows users to use a lower breaking capacity of the protection device of the loading zone if another protection device is installed before with the required breaking capacity. It is a solution for circuits that start at distribution panels that are close to transformers.

As of the 2019.a version, CYPELEC REBT, CYPELEC NF and CYPELEC Core contemplate the possibility of using the breaking capacity of previous protection devices in the design options. The breaking capacity can be that of the fuses or circuit breakers depending on the selection.

The check report includes a comment on the matter in case this option has been used.

Section check of the neutral conductor by harmonic content

The 2019.a version of CYPELEC REBT, CYPELEC NF and CYPELEC Core include the check of the neutral section due to the possible contents of harmonics in three-phase circuits, in accordance with the international code: IEC 60364-5-52, section 524.2.1.

Selection of AWG American calibre cables

The 2019.a version of CYPELEC Core allows users to select AWG (American Wire Gauge) cables.

These cables can be selected in the “Cables” dialogue box (“Configuration” button in the toolbar > “Element library” > “Cables”), where users can choose, as well as the calibres that were available in previous versions, calibres 18 AWG to 2000 AWG.

When the AWG cable selection is activated, their selection is enabled in the line editing panels.

The panel adapts to the selected type of cable (IEC or AWG), in terms of the parameters that define the cable, type of channel and installation method.

The checks are also adapted to the AWG cable selection. For example, the maximum allowable current check is substituted by the amapacity check of the cable according to the American standard (Natinal Electrical Code).

Since, as of this version, users can work on the electrical installation with cables in mm2 or AWG, in order to distinguish lines with IEC or AWG cables, they are drawn in different colours. These colours can be changed in the “Diagram presentation” section of the “Circuit diagram” dialogue box (“Circuit diagram” button of the “Project” section of the toolbar).

Copy the reference of the line to the load

In some panels, as is the panels of circuits with concentrated loads, users can indicate a reference for the circuit and a different reference for the load. When the same reference is to be used for the circuit and the load, a button has been added (next to the reference of the load) to be able to quickly copy the reference.

CYPELEC Core (new program)

CYPELEC Core is a program for the design of low-voltage electrical installations that incorporates the analysis motor of CYPELEC REBT. Users can draw single-line diagrams of the installation and configure the properties of the elements it contains.

It has the same main functionalities of CYPELEC REBT for the load flow and short circuit design, allowing users to edit all the elements with no restrictions on the power or number of lines. Its results output allows users to obtain drawings of the single-line diagram, justification reports, quantity and results tables.

The design checks carried out in the program are based on the specifications of the international IEC standards.

This application is integrated in the Open BIM workflow using the IFC standard, and so maintains the interaction with the rest of the tools.

CYPELEC Core is a free application and can be downloaded exclusively from the BIMserver.center® platform. Its first version can be installed in Spanish or Catalan. It will be available in more languages in upcoming versions.

More information available soon.
