Power & Electrical Services

The HCS Group Power System Team members have years of experience in performing power systems studies, analysis and power system engineering for projects worldwide. The HCS Team can provide full system short circuit analysis, arc-flash studies, coordination studies, load flow, dynamic power system evaluations, and a host of other critical system modeling features.  HCS Group is familiar and capable with working with networks worldwide with varying voltage distribution potentials and frequencies. The Team is well versed in the International Building Codes, European and Asian electrical codes and equipment requirements.

State of the art and the most robust software is utilized in-house by our team of professionals at HCS to model, evaluate and predict real system behavior. Proposed designs can be modeled to enhance the engineering process while existing systems can be modeled to evaluate system vulnerability issues, failure points, modifications and/or upgrade requirements.
