ELECTRICAL POWER SYSTEM ENGINEERING AND CONSULTING

One Line Development: An up-to-date one line diagram of the electrical system is the key to analyzing and understanding how your electrical system will operate under normal and abnormal circumstances. The first step in any technical study is to accurately model the system on a computer from the one line diagram. IES works with our clients to develop a one line diagram or to make an out of date one line current.

Short Circuit Analysis: A short circuit analysis is essential for proper protective device operation and selection of electrical equipment that will safely withstand short circuit conditions. IES is experienced in performing short circuit studies for our clients to ensure their electrical systems are reliable and safe.

Protective Device Coordination: When things go wrong it is the job of your electrical protective devices to remove the failed electrical equipment with minimal disruption to your facility operations. Using computer based software, IES can perform a coordination study that ensures that your electrical protection systems are properly coordinated and that they perform properly.

Arc Flash Hazard Analysis: NFPA 70E requires an arc flash hazard analysis be performed in order to determine equipment flash protection boundaries and the personal protective equipment workers are to use when working on energized equipment. IES is experienced in these studies and delivers to its clients a full written report complete with the NEC required labels for displaying on the electrical equipment.

Load Flow Studies and Analysis: A load flow study will help understand how a complex electrical system works under a variety of system configurations. It helps identify overloaded equipment, analyze various operating configurations for voltage drop and other problems, design facility expansions and structure operations to be efficient and cost effective.

Power Quality Studies: Sensitive electrical loads require clean electrical power to operate properly while other loads can generate unwanted harmonics and transients. Often it is not clear if the Utility or the customer is the source of power quality problems. IES can assist our clients in troubleshooting and diagnosis of electrical power system quality problems.
