In order to offer a more complete set of services to our clients, ITAC has developed a new Power System Studies offering. During this in-depth process, our highly skilled, certified Power System Services engineering team analyzes Power Systems on the worksite.  This client-specific assessment yields insights that are crucial to ensuring employee safety and equipment functionality.

ITAC’s proprietary Power System Study provides electrical hazard protection suitable for any size business. Value-added services included in the Study:

  • Gathering equipment, system, fault current, and protective device data from the client’s worksite and utility company
  • Using SKM Power Tools for Windows to simulate the client’s electrical system
  • Gauging and recording the bolting and arcing fault current, arc flash incident energy, flash protection boundary, required PPE, protective device coordination, and final trip time for each piece of equipment
  • Generating shock hazard and glove class data based on the voltages present at all existing electrical devices
  • Printing arc flash and shock hazard data on 4” x 6” weatherproof adhesive labels for all machinery analyzed and assisting the client with installation
  • Producing an exhaustive report detailing the procedures used to conduct the Power System Study, noting the results of the study, any deficiencies observed, and recommendations on how to increase worker safety and decrease the severity of equipment damage in the unfortunate incidence of electrical system failure

Optional Power System Services:

  • Providing engineering and construction services to reduce the arc flash incidence energy for certain pieces of electrical equipment
  • Recommending changes to protective device settings to reduce clearing time
  • Redesigning protective relaying schemes to enable selective trip settings based on actions such as planned maintenance and personnel proximity detection
  • Incorporating both differential current and light sensing systems into worksites to identify and clear faults faster and detect the presence of electrical arcs sooner than traditional over-current methods
  • Suggesting tools and technologies (e.g., remote breaker racking systems, SCADA control, etc.) to potentially remove employees from harm’s way or eliminate personnel hazard completely
