Engineering Services

Short circuit calculations, equipment withstand evaluation, protective device coordination, and arc flash hazard analysis with labels for are prepared new and existing facilities, utilizing SKM Systems Analysis, Inc. Power Tools for Windows or ETAP software, under the supervision of licensed professional engineer. 

Short Circuit Calculations and Equipment Withstand Evaluation

Available fault currents are determined at locations of interest in the power distribution system in the event of a short circuit. Calculated short circuit values are compared against the equipment’s rated value to withstand a short circuit event without catastrophic failure.

Protective Device Coordination and Arc-Flash Risk Assessment

Recommended settings are provided for adjustable overcurrent protective devices, enabling the isolation of a fault to the smallest portion of the distribution system possible, and reducing large or system-wide outages. Calculated available fault current and overcurrent protective device tripping characteristics are examined to arrive at an incident energy – the level of energy available which could burn or otherwise injure an exposed worker. Custom labels comply with NEC 110.16 and NFPA 70E requirements for warning labels.
