Employee photo Coordination Studies Preserving a safe environment and minimizing equipment loss during a fault are both desired components of any high voltage environment. By selecting the properly sized protective devices according to the results of a coordination study, a power system is able to isolate a fault near the source, preventing a cascading effect which could possibly shutdown any connected asset.

Short Circuit Studies High currents drawn by a short circuit can destroy protective equipment if its capability is exceeded. A short circuit study draws a comparison between equipment manufacturer’s ratings, the systems settings, andthe study resultsto determine the systems short circuit capacity or short-comings. The results of this study can identify problem areas as well as increase both equipment reliability and personnel safety.

Load Flow Analysis A properly designed power system optimizes power consumption while minimizing kW and kVAR losses. By simulating scenarios using computer software, the performance of the power system can be analyzed during the event of an emergency. This study provides insight into the efficiency of the implemented design while decreasing future operating costs.

Power Quality Analysis The performance of your power system affects not only the operation of your load, but also your bottom line. The power quality (PQ) of your system consists of three aspects: power factor, harmonics, and disturbances. A power factor below .90 is considered poor with efficiency loss due to power capacity loss, and the utility can charge you more for its services. Poor power quality can be caused by fluctuations in power factor, harmonics, internal distribution disturbances, internal loads, or the supply. Electronic devices and most non-linear loads are the most sensitive to power quality events. Once an equipment failure or unusual operation occurs, a meter can be installed to record these events over the course of a few hours or days. The collected data is then used to isolate the event, and develop a solution.  Besides troubleshooting, power quality metering (PQM) is utilized for load surveys and preventative maintenance. This tool allows the customer to realize the facilities power system capabilities related to emergency switching, full load testing, or transfer schemes. Proper PQM can prevent lost productivity, lost or corrupt data, damaged equipment, and premature failure of equipment. Types of events that could compromise your system include voltage drop, swell, interruption, inrush current, frequency fluctuations, high-order harmonics, or phase imbalances. 80% of these events exist in distribution or grounding systems due to poor wiring, circuit overloads, or defective electrical devices.


Arc Flash Studies Compliance in this area is becoming increasingly important considering the dangers involved when dealing with arc flash hazards. Having an arc flash study commissioned at your facility brings forward related data including bolted/arc fault levels, incident energy level, flash hazard boundary, worn PPE required, and duration of arc flashing faults. Clearly labeling this information can prevent serious injury or fatality while keeping your facility in NFPA compliance.
