BNS Power services

Engineering, marine and electrical safety services

Expert support across the entire lifecycle of mission-critical power systems for maritime, defense, data center, utility and industrial customers.

Engineering services

Power system studies, performed by engineers who also build the equipment.

For decades our engineers have been at the forefront of power system engineering, using state-of-the-art software and standards.

Flash hazard analysis

Arc Flash Protection Boundaries and PPE requirements, by industry tables or analytical engineering techniques. Essential for commercial, industrial and utility systems.

Load flow analysis

Currents, voltages and phase angles for every bus, used to size current-carrying equipment, identify overloads and locate power factor correction.

Short circuit analysis

Adequacy of interrupting devices and correct instantaneous setpoints, required to size breakers and fuses safely.

Harmonic studies

A two-phase approach: measure system harmonics with recording equipment, then model harmonic load flows and design corrective filters.

System stability analysis

Transient and steady-state studies that determine whether your system returns to normal after short or long-term perturbations.

Engineering documentation

Single-line, three-line, elementary and wiring diagrams created and updated in current software, delivered on paper, electronically or both.
