Electrical Diagnostic Surveys
Arc Flash Analysis & Power System Studies

The NFPA 70E makes it clear the electrical equipment needs to be assessed and labeled properly.

Article 130.5 states: An arc flash hazard analysis shall determine the arc flash boundary, the incident energy at the working distance, and the personal protective equipment that the people within the arc flash boundary shall use.

Electrical Diagnostic Surveys (EDS) can help your company comply with all aspects of the NFPA 70E. Our experts have extensive knowledge and experience with electrical safety, electrical power systems, and the project management experience necessary to comply with today’s standards while having minimal impact on your current operations.

EDS can provide turnkey services for Arc Flash Analysis and Equipment Labeling at your facility. Our approach to projects is below.

Our Project Approach

Power System Data Collection
Data Collection

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.

One-Line Development
One-Line Development

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
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.

Protective Device Coordination
Protective Device Coordination

EDS can provide Protective Device Coordination Analysis in accordance with IEEE std 242-2001; Recommended Practice for Protection and Coordination of Industrial and Commercial Power Systems (Buff Book), and in accordance IEEE std 399-1997; Recommended Practice for Industrial and Commercial Power Systems Analysis (Brown Book). Coordination time-current characteristic curves are prepared to determine the required settings/sizes of the protective devices to maximize selectivity and safety with Arc Flash Hazards in mind.

Arc Flash Warning Equipment Labeling
Equipment Labeling

EDS can help provide equipment labeling procedures. NFPA 70E 2015 requires that electrical equipment, in locations other than dwellings, be marked with an arc flash warning label. Labeling equipment with the requirements of the 2012 NFPA 70E and following safe work practices, does not ensure an electric arc event will not take place. But it does provide personnel with the knowledge and resources to properly protect themselves, mitigate, and some cases, eliminate injury.

Arc Flash Mitigation
Arc Flash Mitigation

Good safety practices take place long before any work is slated to be performed. Electrical Safety and Arc Flash Safety is not any different. The majority of businesses today that are striving to provide a safe workplace and comply with today’s electrical standards are already in operation. In these cases, performing an Arc Flash Analysis and Equipment Labeling is a process that takes place long after the design of a power system. By designing an electrical system from the beginning with Arc Flash and Electrical Safety in mind, many risks associated with Arc Flash can be mitigated or eliminated altogether.
