Low Voltage Engineering and Design

Electrical Design

We produce detailed, constructible deliverables that ensure safety, operability, and regulatory compliance across hazardous and non-hazardous environments.

• Area Classification Plans — Identification and mapping of hazardous zones (IEC/Ex, ATEX, NEC) to guide equipment selection and installation practices in explosive atmospheres.

• Single Line Diagrams and Control Schematics — Clear representation of power distribution, protection schemes, and control logic for reliable system operation and maintenance.

• Substation Layout and Cable Routing — Optimized physical arrangements and 3D-modeled cable trays/routing to minimize congestion, electromagnetic interference, and installation costs.

• Grounding and Lightning Protection — Comprehensive earthing grids and surge protection designs to safeguard personnel and equipment from faults and atmospheric discharges.

• Lighting & Instrumentation Plans — Internal/external illumination studies and instrumentation layouts for safe working conditions and accurate process monitoring.

• Cable Schedules & Interconnection Charts — Detailed inventories and termination diagrams ensuring traceability from source to load.

Electrical Engineering

Our engineering process focuses on robust equipment specification and procurement readiness.

• Design Basis & Load Lists — Establishment of project-specific criteria and comprehensive consumer inventories to drive accurate system sizing.

• Sizing and Selection of Electrical Equipment — Transformers, switchgear, MCCs, UPS, VFDs, generators, and batteries selected for performance, redundancy, and lifecycle cost.

• Specifications, Material Take-Offs (MTO), and Requisitions — Technical specifications and quantified bills of material supporting competitive bidding and supply chain efficiency.

• Vendor Drawing Review and Approval — Thorough evaluation of supplier submissions to ensure compliance with project requirements and standards.

Electrical Studies & Calculations

We utilize industry-leading tools to validate designs and optimize system performance.

• Power System Studies using ETAP — Comprehensive analyses including load flow, short circuit, protection coordination/discrimination, transient stability, dynamic motor starting, arc flash, and harmonic studies to ensure safe, reliable, and selective operation.

• Capacitor Sizing — Power factor correction calculations for improved efficiency and reduced penalties.

• Motor Voltage Drop Studies — Verification of starting and running voltage drops for large drives in critical applications.

• Grounding Calculations — Step and touch potential analysis for personnel safety.

• Cable Sizing — Thermal, voltage drop, and short-circuit withstand verification per IEC/NEC standards.

• Lighting Calculations — Lux level compliance for operational and emergency scenarios.

• Lightning Protection Calculations — Risk assessment and zone protection design per IEC 62305.
