For an unmatched range of power system engineering services, turn to Siemens Short Circuit Study Power system specialists from Siemens will determine the maximum duty that your system’s protective devices, transformers, and interconnections will be subjected to in the event of three-phase and/or line-to-ground fault conditions. In addition, we will provide basic information required to establish protective relay settings. Coordination Study Under fault conditions, systems should isolate the faulted area to minimize disturbance to the remaining system, and simultaneously limit damage to equipment. We will review the characteristics of your protective devices, then provide the settings necessary to ensure that your system functions optimally should a fault occur. Harmonic Analysis As AC drives have become increasingly prevalent in industry, we have seen the introduction of destructive harmonics to many systems. The power quality experts from Siemens will determine the extent and severity of harmonics in your system, then recommend the appropriate means of limiting potential damage. Transient Stability Study This study is particularly valuable for facilities that generate their own power, and those with very large motors. Our power system specialists will study the transient response of rotating equipment following system disturbances and analyze system behavior in relation to the power company tie. Protective Device Evaluation With the objective of achieving optimum protection, we will perform the necessary calculations required to select the interrupting rating of power fuses, circuit breakers, and other protective devices. Power Quality Assessment In recent years, with the proliferation of sensitive electronic equipment, power quality has become a major concern for industry. We perform structured, step-by-step studies with timely diagnosis and expert solutions to the complex challenges of utility and end-user power quality issues. Arc Flash Study NFPA 70E requires that an Arc Flash Hazard Analysis be performed prior to work on electrical equipment. Siemens will determine the incident energy levels, arc flash boundary (AFB), and required level of personal protective equipment (PPE). Grounding Study With the goal of ensuring proper protection and reducing the possibility of excessive transient overvoltages during line-to-ground faults, Siemens engineers will determine and recommend the most appropriate form of system grounding (including derived, low resistance & high resistance). Voltage Unbalance Study Voltage flicker and poor voltage regulation are a common concern on systems with large arc furnaces. The experts from Siemens use this study to develop comprehensive solutions that limit the effects of voltage irregularities and protect sensitive equipment. Applications Engineering Ensuring that large capital equipment such as power transformers and above NEMA motors are properly rated and fulfill design requirements is a complex and difficult process. The consequence of an incorrect rating can add considerably to equipment costs, as well as play havoc with schedules. Siemens will develop the necessary basis of design so that your new or existing equipment is correctly applied and properly specified for subsequent manufacturing, modification, or repair. Installation Design Engineering Siemens will prepare design drawings and specifications such as general arrangements, foundation design, raceway and cable interconnection drawings, grounding plans, and material fabrication drawings for use by construction personnel during equipment installation.
