Data centres rely on robust electrical infrastructure that allows critical systems to operate safely and continuously, minimising downtime and interruptions. An effective earthing system provides protection not only for sensitive equipment but also for personnel.

During high-current earth faults, ground potential rise and hazardous touch and step voltages may occur. An effectively designed earthing grid helps manage these conditions while keeping touch and step voltages within acceptable limits.

ELEK SafeGrid Earthing software allows engineers to design effective earthing systems for critical infrastructure, such as data centres.

Calculate earth grid impedance and ground potential rise. Assess touch and step voltages. Support safer and more reliable infrastructure.

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:
โ€ข Seabed thermal resistivity and burial depth
โ€ข Cable construction and electrical losses
โ€ข Burial or protection systems
โ€ข 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:
โ€ข Ground Potential Rise (GPR)
โ€ข Touch and step voltages across the site
โ€ข 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.

โ€ข Identify equipment or areas that remain exposed
โ€ข Refine mast locations and heights before installation

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

Equipment providing essential safety services, such as fire pumps, must remain operational even during a fire. Consequently, their respective supply cables are required to be fire-resistant to maintain circuit integrity at high temperatures, such as when they are exposed to fire.

Selecting a cable with an unsuitable insulation or temperature rating can lead to:
โ€ข Excessive conductor temperatures
โ€ข Insulation deterioration or failure
โ€ข Reduced current-carrying capacity
โ€ข Loss of supply to critical equipment during an emergency

Calculations for low-voltage networks with a transformer supply can get complicated, especially in the upstream portion.

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:
โ€ข Earth grid and electrode configuration
โ€ข Soil resistivity and multilayer soil conditions
โ€ข Earth fault current and grid potential rise (GPR)
โ€ข Touch and step voltage limits across accessible areas

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

Many modern Moulded-Case and Air Circuit Breakers support interchangeable Electronic Trip Units (ETUs). This flexibility allows engineers to fit different trip units to the same breaker frame instead of completely replacing the circuit breaker, helping achieve the required protection characteristics.

This is valuable during design and commissioning, but it also makes correct ETU selection a critical step in design verification.

Using the wrong trip unit in a protection coordination study can result in:
โ€ข Incorrect time-current characteristics (TCCs)
โ€ข Inaccurate coordination and selectivity assessments
โ€ข Protection settings that do not reflect the installed equipment

๐—˜๐—Ÿ๐—˜๐—ž ๐—–๐—ฎ๐—ฏ๐—น๐—ฒ ๐—ฃ๐—ฟ๐—ผ ๐—ช๐—ฒ๐—ฏ helps address this issue by providing a list of available ๐—ฒ๐—น๐—ฒ๐—ฐ๐˜๐—ฟ๐—ผ๐—ป๐—ถ๐—ฐ ๐˜๐—ฟ๐—ถ๐—ฝ ๐˜‚๐—ป๐—ถ๐˜ ๐—ผ๐—ฝ๐˜๐—ถ๐—ผ๐—ป๐˜€ for compatible circuit breaker models.

By accurately selecting the trip unit, engineers can:

โ€ข Model the actual protection device installed
โ€ข Generate more accurate protection coordination studies
โ€ข Compare different trip unit options without changing the breaker frame
โ€ข Improve confidence that the study matches the actual installation

Accurate protection coordination starts with accurately modelling the protection device. Allowing engineers to select the appropriate electronic trip unit helps ensure studies reflect real-world installations.
