Dimensionamiento de cables y cuatro verificaciones
Verificaciones de ampacidad / caída de tensión / térmica / mecánica (GB 50217-2018, IEC 60287).
Preparation
The exact input requirements follow the required fields on the tool page.

Check cables, instrument transformers, insulation and grounding separately, and organise the basis for equipment and line selection.
For engineers preparing distribution schemes and checking equipment conditions, and for project and procurement teams gathering data.
Review the matching calculation or check results, the inputs and any unconfirmed items. The actual output depends on the tool once it is wired up.
A single result does not prove the whole scheme compliant, the equipment suitable or the work ready to build. Site conditions, manufacturer data and specialist review still apply.
Read the scope and input requirements first, then open the matching tool. No tool replaces another's engineering check.

Selección de transformadores de corriente y tensión: relación, clase de precisión y carga nominal con las verificaciones ítem por ítem (límites de relación, carga secundaria, factor límite de precisión, resistencia térmica de corta duración y dinámica) — calculado por el motor, gráficos incluidos.

Introduzca la tensión del sistema, el grado de contaminación, la altitud y la tensión residual del pararrayos; el motor selecciona el nivel de aislamiento normalizado (IEC 60071-1), aplica la corrección por altitud (IEC 60071-2 Anexo H) y devuelve la tensión soportada requerida y el menor nivel normalizado que la cumple, sin necesidad de esquema.

Tools that are not open yet are rendered non-clickable per site rules; no link that would 404 is provided.
A page existing does not mean the function is accepted; results still need review against the applicable conditions.
Supply and load conditions, equipment parameters, line and environment data; the required fields follow the chosen tool.
List missing data as to-be-confirmed first; never invent parameters just to enter a flow.
Separate existing data, assumptions and inputs that still need confirmation.
Use nameplate, design or measurement records; do not compare values of different conventions directly.
Having data is not completeness; completeness comes from checking fields, units, relations and scope of use.
Quick entries only; the page still belongs to the six site sections.
Different tasks may reference the same page; this does not change the page's section.
Move forward and back within the same top-level section; no jumping to another task taxonomy.
