Electrical· Release 2.68

Electrical design software for cables, short circuit and protection.

The Electrical Design Bench takes a design from the load schedule and maximum demand to cables with derating and voltage drop, short circuit to IEC 60909, protection and discrimination with manufacturer curves, and arc flash to IEEE 1584-2018 — then checks a contractor's submission against the same calculations. ASH ELDAS brings the electrical benches together in one online product you can try for 30 days.

What it covers

From the load schedule to the network study.

Concept, detailed design and design verification run on the same engines, so the schedule, the study and the review never disagree.

Load schedule & cables

Load schedule and maximum demand; cables with derating and voltage drop; busducts. Cable, busduct and termination schedules are built from the boards and circuits, with cumulative voltage drop — exported to Excel in one click.

Short circuit & protection

Short circuit (IEC 60909), protection and discrimination with manufacturer curves. In ELDAS the study network is built from the LV and MV tabs: load flow, short circuit, discrimination, motor starting and power quality.

MV protection grading

50/51 and 51N settings per device, operating times at 2, 5, 10 and 20 × Ip, CT class and burden.

Arc flash & life-safety supplies

Arc flash to IEEE 1584-2018; life-safety supplies; lighting; single-line and riser diagrams.

Earthing & lightning protection

Soil resistivity and electrodes, IEEE 80 substation grid (touch and step voltages), building and plant earthing, ICT clean earth, lightning protection to IEC 62305 and NFPA 780 with a roof plan.

Solar farm

EPW or monthly irradiance, energy yield and performance ratio, string sizing, DC cables and fuses, inverter count, step-up transformers and the MV collector.

Review the contractor's schedule

Paste a contractor's cable schedule: missing and extra cables, ratings, voltage drop with the scheduled length, cores, segregation and spares are re-checked line by line.

Inside the bench

Boards, schedules, grading and studies — from one project.

Screens from the built-in example project of ASH ELDAS F3.4. Every figure carries the clause it was checked against.

ELDAS Electrical LV tab, Boards and feeders page: distribution boards with feeder type, length, method, group factor, parallel cables, diversity and rating, and the submitted feeder design checked for Ib ≤ In, Ir ≤ Iz and voltage drop — **Boards & feeders**Demand carried up the board tree; the submitted cables and breakers checked line by line.

Cable schedule in the Electrical Design Bench with size, CPC, length, design current, protective device, current rating and voltage drop for each cable — **Cable schedule**Cable, busduct and termination schedules built from the boards and circuits, with cumulative voltage drop — exported to Excel in one click.

ELDAS MV tab, MV protection grading page: relay settings and operating times per incomer, feeder and transformer, and the CT selection table — **MV protection grading**50/51 and 51N settings per device, operating times at 2, 5, 10 and 20 × Ip, CT class and burden.

ELDAS Studies tab, Short circuit page: bus fault levels Ik3, Ik1, Ip and Icw against busbar withstand, and the device duty table — **Network studies**Load flow, short circuit, discrimination, motor starting and power quality on the network built from the LV and MV tabs.

Stages

Concept, detailed design, verification — the same engines throughout.

A concept scheme, the detailed design and the reviewer's check are run by the same code, so they never disagree with each other. Choose the stage when a project starts; develop a concept into the detailed design in one click.

1 · Concept design

From a few inputs to a sized scheme

Floor areas, occupancy, grid, flows, population
Plant sizes, member sizes, main feeders, storage, quantities
For options, budgets and early coordination

2 · Detailed design

Every element, every check

Element-by-element sizing with code checks and clause references
Diagrams, schedules, single-line and riser diagrams, SVG export
Calculation report for submission; Excel and CSV schedules

3 · Design verification

Independent check of a design by others

Submitted values beside the calculated ones
Review codes A / B / C with the clause; CRS comment rows
Rev.xx resubmission cycles; value-engineering opportunities

Questions

Which codes and standards do the benches use?

The Saudi Building Code set (SBC 201, 301, 304 and 801) and the Saudi Civil Defence regulations, ACI 318 and ASCE 7, AISC 360-22, the International Codes (IBC, IPC, IMC, IFC), NFPA 13, 14, 20, 72, 92, 101 and 2001, NEC and IEC 60364 / 60909 for electrical, IEEE 1584 for arc flash, ASHRAE Fundamentals for HVAC, ASME B31.3, API 520, ISO 5167 and IEC 61511 for piping and instruments, IEC 62676-4 for CCTV, and QCS 2014 with the Qatar Civil Defence guidelines among others. Every check names its clause, and each requirement pack states the edition it quotes.

What is the difference between ASH ELDAS and the Electrical Design Bench?

ASH ELDAS F3.4 is the electrical-only product composed from the suite's electrical benches: eight tabs — Project, Electrical LV, MV, Lighting, ELV & ICT, Earthing & Lightning, Solar Farm and Studies — with one load register and a check register that rates a compliance statement. The Electrical Design Bench is the single-file bench inside the full Design Suite.

Can I bring in the contractor's schedules?

Yes. Import data in any bench reads Excel, CSV, pasted tables and DXF; the Data Import tool also reads schedules from text PDFs and traces single-line diagrams. Cable and instrument schedules can be checked line by line against the calculation.

Is my project data sent anywhere?

Your project never leaves your computer: the benches and ELDAS keep projects in the browser and in the files you save. The pages serve their own fonts; the trial applications still load their web fonts from Google Fonts. See the privacy notice.
