What this is
Check cables, instrument transformers, insulation and grounding separately, and organise the basis for equipment and line selection.
Who it is for / at what stage
For engineers preparing distribution schemes and checking equipment conditions, and for project and procurement teams gathering data.
What you can review
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.
Boundaries
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.
Next step
Choose what you need to check
Read the scope and input requirements first, then open the matching tool. No tool replaces another's engineering check.

حاسبة تنسيق العزل
أدخل جهد النظام ودرجة التلوث والارتفاع والجهد المتبقي لمانعة الصواعق؛ يختار المحرك مستوى العزل القياسي (IEC 60071-1)، ويطبق تصحيح الارتفاع (IEC 60071-2 الملحق H) ويعيد جهد التحمل المطلوب وأصغر مستوى قياسي يحققه - دون الحاجة إلى مخطط.

Status
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.
Preparation
Prepare the data, then choose a tool
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.
Confirm voltage, equipment and operating conditions
Separate existing data, assumptions and inputs that still need confirmation.
Keep the source and unit of each parameter
Use nameplate, design or measurement records; do not compare values of different conventions directly.
Check the required fields for the chosen tool
Having data is not completeness; completeness comes from checking fields, units, relations and scope of use.
