Power System Engineering

A short circuit and coordination study helps to avoid accidents, productivity losses, costly fines, and higher insurance costs. By evaluating a system’s protective devices and the circuits they protect, a coordination study determines how long equipment can sustain operation without damage or failure. These studies provide power transformers, switchgear, substations, motor control centers, panelboards, and other equipment with the required protection to ensure minimum service interruption under overload and short-circuit conditions.

Electrical hazards such as electrical shock and arc flash impact workers every day in the United States. An arc flash analysis can help determine the presence and location of potential hazards and provide recommendations for Personal Protective Equipment (PPE) and flash protection and safe work practices. National Fire Protection Association (NFPA) requires this analysis be performed at least every five years or as modifications or expansions to your electrical distribution system are made, or as changes occur in the electric utility system. Vertiv’s team of registered professional engineers review and stamp each arc flash analysis ensuring accuracy and compliance.

Today’s increasing sensitivity of advanced process controls and industrial machinery as well as sophisticated IT equipment require a higher level of power quality to ensure smooth operation and extended service-life of the equipment. Vertiv engineers help identify the source of the disturbances such as grounding errors and harmonic distortions and recommend solutions to ensure optimal system performance.

Load flow studies help identify and correct power system issues, such as overloads, load imbalance, harmonic problems, poor power factor, or other factors that may be causing operational inefficiencies or performance problems. Our power system engineers will evaluate component and circuit loading, power factor and system losses and real and reactive power flow and provide recommendations to help you fine-tune your electrical system for optimal efficiency and capacity.

A grounding system is one of the most important, yet neglected, segments of a critical facility’s electrical power system. Proper grounding is essential to ensure personnel safety and service reliability. Vertiv’s Electrical Reliability Services can provide a study on a proposed substation ground grid design to ensure safer and more cost-effective ground grids.

Vertiv’s protection and control engineers can help determine the best configurable relay settings and logic to provide maximum system protection, advanced functionality, and compliance with NERC requirements. Our engineers will take time to fully understand and define your system's requirements, such as how the protection system should respond in the event of a fault, how protective relays should communicate with other systems, and what functions, in addition to protection, the relays should perform.

Vertiv engineers can help modify existing CAD drawings or create new drawings such as one-line diagrams, control schematics, wiring drawings, panel elevations and more. We have the applied installation experience and a quality process to ensure the creation of accurate and precise diagrams and schematics of your existing or newly updated system.
