The reliability and redundancy of an emergency power system can be measured by a system operators ability to perform preventative maintenance on equipment components and devices without disruption to the facilities critical loads.
Understanding and correctly defining standards that will fulfill these objectives are key factors in achieving maximum system reliability.
Establishing either Level 1 or Level 2 systems for equipment installation, performance and preventative maintenance are initial steps carried out in the design development stage of a project.
Emergency Power Supply System (EPSS) classifications and types are also necessary, and required to be in accordance with NFPA 110 Table 4.1 (a) and Table 4.1 (b).
Professional design engineers are responsible for identifying system load distribution as either “emergency,” “legally required standby” or “optional standby” system per Articles 700, 701 and 702 of NFPA 70 respectively.
Standards for system performance, equipment arrangement, power source connections and other countless details are what ultimately make up a project's basis of design.
Depending on project type, code review may also include:
NFPA 99: Health Care Facilities Code
Essential Electrical Systems (EES)
NFPA 101: Life Safety Code
Typical Project Specific Considerations:
1. Application (emergency, standby, legally required, life-safety, etc.)
2. Sizing and load types (resistive and inductive reactance).
3. Location (Indoor, outdoor, rooftop, etc.)
4. Noise and sound attenuation concerns.
5. Exhaust, prevailing winds and building air systems.
6. Fuel types, dual fuel, bi-fuel and storage.
7. Generator enclosures and concrete equipment pads.
8. Load bank options and emergency power load monitoring.
9. Automatic load selective pickup and load shedding to ensure adequate power to legally required systems.

Engineering Peer Review and Quality Assurance Load Flow Studies, Power Disturbance Analysis, Technical and Performance Specifications, Risk Analysis and Rehabilitation Planning, Feasibility Studies and Due Diligence Reports.
Short Circuit Analysis, Selective Over Current Protective Device Coordination, NFPA 70E Compliant Arc Flash Labeling
All of our short circuit studies studies are modeled on the most recent version of "SKM" Power Tools for Windows.
Study modules include DAPPER, CAPTOR, A_FAULT, IEC_909, IEC_363, Equipment Evaluation and Arc Flash.
Note: Real Power Engineers can provide arc flash label printing and field application services for adhering labels to electrical system equipment.
Power Systems data modeling allows us to provide our clients with a best practices approach to solving the most challenging of engineering problems.
Capable of exceedingly technical calculations; power system modeling is used to execute computations for load flow, voltage drop, motor starting transients, demand load studies, feeder and transformer sizing.
Equipment evaluation studies are used to compare equipment and protective device interrupt ratings against worst case system short circuits calculated throughout the power distribution system.
Arc flash studies compute the incident energy and arc flash boundary points for each location in a power system. This power module helps aid in preparing designs that comply with NEC 110.16, OSHA, NFPA 70E and IEEE 1584 standards.
A short circuit study will help ensure that personnel and equipment are protected by establishing proper interrupting ratings.
Periodic Engineering Field Observation
Validate compliance with codes and standards during construction with engineering field observation. This service allows owners and stakeholders to take control over the quality of workmanship and materials used; while duly so gaining the critical knowledge of how the planned system should work.
