Regularly Scheduled Classes

OneLiner Class

ASPEN OneLiner classes are held twice a year. Class duration is three days. The class is designed for engineers who are using ASPEN OneLiner to perform short circuit and relay coordination studies and wish to become more proficient in using the program. Class includes hands-on training of system modeling, short circuit studies and protective equipment studies.

DistriView Class

At least one ASPEN DistriView class is held every year. Class duration is two days. This class is designed for distribution system engineers who use ASPEN DistriView to perform short circuit, relay coordination and voltage drop studies and wish to become more proficient in using the program. The course material is intended for beginning to advance levels and will include hands-on training of system modeling, short circuit studies and protective equipment coordination studies.

Course brochure and online registration form will be available in the Events page at least three months before each class.


On-Line Training Sessions

Short on-line training sessions on various special topics related to ASPEN software are offered regularly. The sessions are conducted on Microsoft Live Meeting platform. Participants are required to have internet connection and Microsoft Live Meeting client software on PC computer to take part in the training.

Schedule, brochure and on-line registration form will be available in the Events page at least one month before each session.


On-Site Training

Having training classes on site is a good alternative to sending the engineers to the regularly scheduled classes, especially for large organizations that have many users that need to be trained in the use of ASPEN software. We have setup a Certified Trainer program to provide this service.

Each Certified Trainer is:

  • An engineer with many years of experience in the electric utility industry.
  • A long-time user of ASPEN software.
  • A good teacher and a good listener, capable of explaining complex concepts to other engineers.

ASPEN requires the trainers to take refresher courses regularly to keep up with the latest changes in the software. We review their certification annually.

Their biographical information of the trainers is shown below, in alphabetical order of their last name. The trainers are not employees or contractors of ASPEN. For this reason, you must write or call them directly if you are interested in the services they offer.

Srdjan Dimitrijevic

Srdjan Dimitrijevic has a BScEE (1998), MScEE (2002) and PhD (2012) from University of Belgrade, Serbia. Srdjan gained relay protection experience from working in a utility and from consulting services internationally for various power generation, renewable generation, transmission, and distribution projects. He has also worked in projects that cover a power system’s lifecycle, starting from developing of a power system master plans on a national level, planning and project execution of new power plants (i.e., substations, power generation plants, etc.), and analysis of existing power systems on a national and/or plant level, including individual fault investigations.

Srdjan has used ASPEN OneLiner extensively for short circuit calculations and relay protection setting studies on new and existing power systems. He is also experienced in other ASPEN products including Relay Database, Line Database, Breaker Rating Module, Power Flow Program, and DistriView. He can provide training courses on all ASPEN products to new users (delivered during an ASPEN product purchase process) and/or experienced users (delivered usually after a Relay Protection Analysis Study project in which Srdjan was involved). Srdjan speaks English and Serbian fluently.

Srdjan is a Senior Member of IEEE and Serbian Chamber of Engineers. He is also author and reviewer of a number of papers in internationally recognized journals related to power systems. His major prior assignments were in Europe and the Middle East.
