SHORT CIRCUIT STUDIES are done to analyze the magnitude of currents flowing throughout the power system at various times after a fault has occurred.

1) Calculates fault currents at various locations within the plant.
2) Identifies whether the power system and equipment can withstand the available fault current.
3) Improve the total reliability of the power system.
4) Specifies the equipment ratings for future expansions.

ARC-FLASH HAZARD STUDIES are an essential part of an effective plant electrical safety program. The study will identify the proper Personal Protective Equipment (PPE) and safe working distances from potentially dangerous elctrical equipment. This comprehensive study includes:

1) Verifying and updating the plants one-line power diagram.
2) Determine the fault currents available at key locations in the electrical system.
3) Determine safe working distances and proper safety attire when fixing equipment.
4) Provide arc flash hazard labels to put on equipment.

COORDINATION STUDIES are done to select proper settings or sizes for relays, breakers and fuses, thus avoiding extensive plant outages and safety.

1) Set the protective devices to trip in a desired sequence during the fault condition.
2) Isolate the problem area from the entire power system.
3) Ensure that all the equipments are adequately protected.
4) Improve the total reliability of the power system.

LOAD FLOW STUDIES are performed by a computer to simulate normal power system operating conditions to evaluate bus voltage profiles, real and reactive power flows, and losses resulting from motor starting or other transient loading conditions to prevent overloading, brownouts, and under/over voltage conditions.

1) Bus Voltage Profiles.
2) Proper Transformer Tap Settings.
3) Component or Circuit Loading.
4) Real and Reactive Power Flow.
5) Power System Losses..

POWER FACTOR STUDIES are performed to maintain and improve the power factor between the real to apparent power consumed by the plant. By maintaining a high power factor, the plant may avoid costly utility bills and is more efficient. Since loads etc. change, the power factor of a plant will vary over time.

1) By improving the power factor, Bus Voltage profiles are improved.
2) As a result of increased power factor, power system capacity (KVA) is increased.
3) Improved power factor will also help to reduce losses.

EQUIPMENT EVALUATION STUDIES is an extension of the short circuit study. This study compares component short circuit ratings and continuous ratings with calculated short circuit and operating condtions.

1) Calculates fault currents at various locations within the plant.
2) Avoid extensive equipment, system damage and personnel injury by underrated equipment in the event of a fault.
3) Recommend replacements to failed equipment.

AS BUILT ONE-LINE DIAGRAMS of the electrical system are reviewed and updated to help ensure the safe, reliable operation of your facility.

1) All the electrical information required for the studies from the plant is collected..
2) If needed, we can send a sample form for most equipment and system data.
3) Based upon all the collected information, single-line diagrams are created to show the current configuration and modes of operation of the system.

GROUND GRID DESIGN is done to review existing lightning protection or protection from the occurance of a fault to the ground.

1) Identifies high soil resistivity.
2) Evaluate shock hazards in substations or other ground mat enviroments.
3) Reviews and recommends backup protection times.

HARMONIC ANALYSIS is done to solve problems associated with harmonics in an industrial facility that include excessive heating and losses in motors, generators and transformers. These studies evaluate harmonic voltage and current distortion at the point of common coupling with the utility.

1) Identifies problems and recommend changes in design or components.
2) Helps to improve the total reliability of the power system.
3) Ensure compliance with IEEE Standard 519-1992.

TRANSIENT ANALYSIS studies transient overvoltages which can be caused by a number of power system switching events to determine if the power electrical system will remain stable after the disturbance and to establish necessary load shedding requirements where applicable.

1) Identifies switching events and monitors voltages during the events.
2) Isolate potential voltage problems and identify component changes/additions.
3) Recommend changes during high switching times to minimize potential power system trips or equipment damage.

LOAD FORECASTING is done to analyze the potential impact on the electrical system and for future expansion of the plant.

1) Collect all data on known equipment in the plant and compares it with the known capacity of the electrical power system.
2) Recommends additions or improvements to meet future expected loads.
3) Calculates present utilization to the expected 100% present capacity of the electrical power system.

DYNAMIC SIMULATION STUDIES are done either at the early stage of the conceptual design of the plant or at a later state in the enhancement of the existing equipment and/or control strategy concerning operability and safety of the solutions to adopt. This study is very beneficial in the Process Industry.

1) Simulate adequacy of the plant under normal or abnormal conditions.
2) Simulate of advanced control strategies in process control.

CABLE PULL AND AMPACITY STUDIES are done to analyze the ampacity and/or operating temperatures of cables in various raceway systems.

1) Create accurate prediction of cable pulling forces.
2) Make cable recommendations to meet the most economical design requirements.

TURBINE FAILURE ANALYSIS is done to identify the root cause of the turbine failure, whether it be in component failures or operational errors.

1) Study events and conduct interviews of personnel that lead up to the turbine failure.
2) Do metallurgical failure analysis if necessary.
3) Review, study design and application perimeters of equipment.
4) Submit analysis of failure and recommendations.
