Power System Study Service

Our Company is specialized energy service company in Energy Audits, Measurements & Verification and Implementation of Energy conservation Measures.

We perform a variety of power system studies, including short circuit studies, protective device coordination studies and arc flash studies. All of our power system services are designed to maximize power quality, improve power system performance and reliability, and increase personnel safety. Our extensive experience in the electrical power distribution industry, in combination with the latest engineering software, produces electrical engineering documentation of the highest quality.

Our team of expert engineers utilizes the industry’s most popular electrical engineering software. Our experienced team in power system studies enables us to provide power system studies in a very confident and professional manner.

 Short Circuit Study

A short circuit study can help minimize the consequences of a potential fault in your power system by helping identify the ideal short circuit ratings for your switchgear. For example, short circuit interrupting equipment such as circuit breakers and fuses should have ratings greater than the short circuit duties calculated by the study.

When ratings for your power system are too low, equipment may fail to interrupt a short circuit or ground fault. This leads to more widespread effects throughout your electrical power distribution system as more switchgear fail.

 

 Protective Device Coordination Study

A Protective Device Coordination Study recommends settings for adjustable protective devices, which minimize disturbances due to system faults. These devices include switchgear, protective relays, and circuit breaker trip devices, all of which can provide automatic tripping during disturbances.

 

Recommendations may also be made for revising the type of protective device that is applied. The prime consideration of a coordination study is minimizing the part of the system that is disconnected to remove a fault of abnormal condition. This permits continued operation for the greatest possible remainder of the power system.

Study results are also used to specify protective relays and circuit breaker trip settings, and for establishing impedances of current limiting reactors.

Arc Flash Study

An arc flash study helps reduce the risk of serious personnel injury and death in the event of an arc flash. It requires making sure that proper safety precautions are taken and adequate personal safety equipment (PPE) is worn according to NFPA 70E, IEEE 1584, NEC 110.6, and OSHA standards. An arc flash study calculates the incident energy and arc flash boundary for any point in a power system. Custom flash labels are generated that comply with NEC 110.16 requirements helping to further ensure a safe and productive workplace.

We identify approach boundaries and appropriate levels of PPE for employees to access the panels.

 

Deliverable of an Arc Flash Study Includes but not limited to:

  • Detailed report of findings and recommendations including methods to reduce Arc Flash incident energy levels and enhance worker safety.
  • PPE category recommendations for all electrical equipment within the scope of the study.
  • Arc Flash incident energy equipment labels listing PPE category recommendations for attachment to existing enclosures.
  • Onsite electrical safety training for company personnel.
