Our Project Approach
Collecting the proper data from your power system is the most important aspect of the arc flash analysis. Having correct and concise data is vital to achieving accurate results. EDS offers many options for data collection to best suit your needs. Some of these options include off-site supervision and guidance of site personnel or local contractor, or onsite data collection working with site personnel or local contractor.
The one-line diagram is the basis of analysis. Data collected in the field is entered into engineering software to build a snapshot of your existing power system. Once this data is entered, many different types of power system analysis can be performed such as: Short Circuit Analysis, Protective Device Coordination, Load Flow Analysis, Harmonic Analysis, and Arc Flash Analysis.
Short Circuit Analysis
EDS can provide Short-Circuit Analysis in accordance with IEEE std 551-2006; Recommended Practice for Calculating Short-Circuit Currents in Industrial and Commercial Power Systems (Violet Book), in accordance IEEE std 399-1997; Recommended Practice for Industrial and Commercial Power Systems Analysis (Brown Book), IEEE std 141-1993; Recommended Practice for Electrical Power Distribution for Industrial Plants (Red Book), and ANSI C37.010, C37.13, C37.5.
