Mining facilities often include dedicated substations and distribution systems that supply high-demand equipment such as crushers, conveyors, pumps, ventilation systems and processing plants.

The cables feeding these loads must be sized for both the required load and the actual installation method. An inadequately rated cable can operate at excessive conductor temperatures, accelerating insulation ageing and reducing cable life.

IEC 60287 calculations can be challenging, especially when performed manually, as they require consideration of several factors, including:
• Buried cables, ducts and engineered backfills
• Multiple circuits and mutual heating
• Different soil thermal properties and ambient conditions
• Complex cable arrangements where heat dissipation is restricted

ELEK Cable High Voltage performs cable rating calculations in accordance with IEC 60287 or using the Finite Element Method (FEM), enabling engineers to build an accurate thermal model of the cable system and its actual installation.

Correctly rated cables help keep mining operations running at the required load within temperature limits, without unnecessarily oversizing critical distribution circuits.

High-voltage cable systems are often installed in ventilated tunnels where accessibility, maintainability, and effective heat dissipation are critical design factors.

A distinct feature of this installation is that the cable rating also depends on the forced airflow through the tunnel and the tunnel's thermal characteristics. Accounting for these factors properly is essential for accurate, optimised ampacity calculations in accordance with IEC 60287.

Hand calculations are impractical here. The process is iterative, requiring engineers to determine how cable losses interact with the thermal environment, tunnel geometry, thermal properties, and ventilation conditions simultaneously.

The 𝗘𝗟𝗘𝗞 𝗖𝗮𝗯𝗹𝗲 𝗛𝗶𝗴𝗵 𝗩𝗼𝗹𝘁𝗮𝗴𝗲 software simplifies this process with its dedicated 𝗩𝗲𝗻𝘁𝗶𝗹𝗮𝘁𝗲𝗱 𝗧𝘂𝗻𝗻𝗲𝗹 installation module. Engineers can simply input:
• Tunnel dimensions and depth
• Tunnel wall thermal resistivity
• Air velocity through the tunnel
• (𝘖𝘱𝘵𝘪𝘰𝘯𝘢𝘭) Inlet air temperature

The software then performs the IEC 60287 calculations, accounting for cable derating due to the tunnel's thermal environment. Engineers can obtain reliable ampacities faster, with less calculation time and greater confidence in the final design.

Remote offshore facilities are often supplied via high-voltage submarine cables from onshore supplies or other remote generation sources.

Unlike conventional cable system installations, submarine cables are exposed to complex thermal environments, with their current-carrying capacity influenced by a number of factors:
• Seabed thermal resistivity and burial depth
• Cable construction and electrical losses
• Burial or protection systems
• Nearby cables and mutual heating

Inaccurate assumptions can lead to cables operating at excessive conductor temperatures or, conversely, overly conservative ratings that restrict the amount of power that can be transferred. For submarine links running across vast distances, correcting an unsuitable design or installation after deployment is difficult and can be extremely costly.

ELEK Cable High Voltage provides a platform for accurate IEC 60287 assessment of submarine power cable capacity, accounting for these subsea thermal conditions.

By modelling the actual cable construction and its surrounding thermal environment, engineers can determine appropriate current ratings and identify thermal constraints before the cable system is installed, helping to avoid costly mistakes and unnecessary rework.

Battery Energy Storage System (BESS) facilities are becoming increasingly important in modern power systems and distribution networks, largely by supporting renewable energy integration, grid stability and reliable power supply.

However, BESS facilities involve high-power equipment, such as battery systems, transformers, inverters and switchgear. During an earth fault, high fault currents can flow through the facility's earthing system, potentially leading to hazardous touch and step voltages across the site.

High-touch and step potentials can expose personnel to dangerous voltages, particularly around equipment, metallic structures, and other accessible areas.

ELEK SafeGrid Earthing allows engineers to assess earthing system performance and design safer grid configurations by evaluating:
• Ground Potential Rise (GPR)
• Touch and step voltages across the site
• Earthing grid geometry and conductor arrangement

With accurate touch and step voltage calculations, engineers can refine their designs to reduce hazardous voltages and ensure they remain within applicable safety limits.

Elevated module substations, which are common in industrial facilities, often require dedicated lightning protection systems provided by the substation's manufacturer. Due to the substation's exposed location and elevated installation, critical equipment must be protected against potential lightning strikes.

Without a properly designed lightning protection system, a direct lightning strike can damage transformers, switchgear, control systems and auxiliary equipment located in the substation, potentially causing costly outages and safety concerns.

The 𝗟𝗶𝗴𝗵𝘁𝗻𝗶𝗻𝗴 𝗣𝗿𝗼𝘁𝗲𝗰𝘁𝗶𝗼𝗻 𝗠𝗼𝗱𝘂𝗹𝗲 𝗶𝗻 𝗘𝗟𝗘𝗞 𝗦𝗮𝗳𝗲𝗚𝗿𝗶𝗱 𝗘𝗮𝗿𝘁𝗵𝗶𝗻𝗴 allows engineers to apply the rolling sphere method to:
• Position lightning masts around elevated structures, such as a modular substation
• Visualise the resulting protection zones at various heights
• Identify equipment or areas that remain exposed
• Refine mast locations and heights before installation

This helps engineers assess lightning protection coverage for the complete substation structure and its electrical equipment.

• Excessive conductor temperatures
• Insulation deterioration or failure
• Reduced current-carrying capacity
• Loss of supply to critical equipment during an emergency

The AS/NZS 3008 Cable Sizing Calculator in the 𝗘𝗟𝗘𝗞 𝗖𝗮𝗯𝗹𝗲 𝗣𝗿𝗼 𝗪𝗲𝗯 software allows engineers to select high-temperature XLPE/elastomer insulation and reference the appropriate cable sizing tables from the standard.

This helps engineers determine the appropriate conductor size and current rating for the selected insulation and installation conditions while meeting fire-rated and circuit-integrity requirements.

Electric vehicle (EV) charging infrastructure may include multiple high-power chargers, distribution equipment, switchboards and other electrical equipment with exposed conductive structures that are frequently accessed by the general public.

As with any electrical facility, an effectively designed earthing system is required to safely dissipate earth fault current. The system's performance is assessed by calculating touch and step voltages and ensuring they are within the calculated limits in accordance with the applicable standard.

For large charging facilities, the earthing design may need to consider:
• Earth grid and electrode configuration
• Soil resistivity and multilayer soil conditions
• Earth fault current and grid potential rise (GPR)
• Touch and step voltage limits across accessible areas

The 𝗘𝗟𝗘𝗞 𝗦𝗮𝗳𝗲𝗚𝗿𝗶𝗱 𝗘𝗮𝗿𝘁𝗵𝗶𝗻𝗴 software provides a practical way for engineers to model earthing grids associated with EV charging hubs and calculate grid performance, including GPR, touch and step voltages.

This allows engineers to identify potentially hazardous areas and assess whether the proposed earthing design provides adequate protection for people around the charging infrastructure.
