Power supply systems design

We engineer industrial power distribution networks, perform electrical load calculations and short-circuit analyses, select protective switchgear, and deliver comprehensive design documentation for power, grounding, and industrial lighting systems.

Industrial Power Equipment & Distribution

We quantify electrical demand loads, establish power reliability categories, design single-line power distribution architectures, and specify primary electrical equipment.

Engineering activities include:

• Electrical load balance and maximum demand calculations
• Short-circuit current calculations (IEC 60909)
• Selection of circuit breakers, contactors, and protective relays
• Protective device coordination and relay selectivity studies
• Sizing transformers, electric motors, and variable frequency drives (VFDs)
• Developing single-line diagrams (SLDs) and schematic wiring drawings
• Drafting technical equipment requisitions and procurement specifications

Cabling Infrastructure & Containment Routing

We detail medium/low voltage power, control, instrumentation, and fieldbus cabling infrastructure.

We determine cable routing, select conductor types and cross-sections, and calculate ampacity limits and voltage drop allowances. Designs account for environmental ambient limits, fire propagation safety, Ex hazardous area classifications (ATEX), electromagnetic compatibility (EMC), and physical redundancy requirements.

Documentation deliverables include cable routing layouts, cable schedules, field connection diagrams, material specifications, and structural cable tray design packages.

Switchgear & Low Voltage Switchboards

We engineer main distribution boards (MDBs), motor control centers (MCCs), control panels, and low-voltage switchgear assemblies.

We establish internal equipment layouts, busbar ratings, ingress protection (IP/NEMA) ratings, switching configurations, and redundancy architecture. Deliverables comprise single-line diagrams, schematic diagrams, physical enclosure arrangements, I/O signal lists, and bill of materials (BOM).

Grounding & Lightning Protection Systems

We design protective earthing (PE), clean functional grounding (FE), equipotential bonding networks, and direct lightning protection systems.

Designs evaluate electrical plant specifications, civil steelwork, process vessel isolation, and ATEX explosion boundaries. We perform ground grid resistance calculations and issue installation plans, connection diagrams, and bill of materials.

Industrial Indoor & Outdoor Lighting

We design operational, emergency, escape route, and exterior perimeter lighting systems for hazardous and non-hazardous industrial facilities.

We perform photometric lux calculations, select luminaire fixtures, determine placement grid layouts, and design power distribution and control circuits. Systems emphasize energy efficiency, ingress protection, explosion proofing (Ex d / Ex e), and maintenance access.
