Course Information

This course is the virtual version of APP 3530 and is only available to students in the US. We currently do not have any eAPP 3530 courses scheduled. Click “contact us” and you will be added to the waitlist.

Course Base Fees: $1,500 USD

eAPP 3530 will guide you through configuring a realistic communications scheme using the SEL-3530 RTAC. This self-paced course has recorded lectures, activity-based exercises, and three weekly check-ins. An instructor will be available to assist individually or during the weekly class web conference sessions.

Students will have access to the eLearning content for eight weeks.

Equipment includes: (1) SEL-3530-4 RTAC, (1) SEL-751 Feeder Protection Relay, (1) SEL-2725 Ethernet switch, (1) portable 19" rack, prewired and prepopulated with the above items.

Each week, you will be tasked with watching the recorded lectures and completing the exercise for each section. At the end of the week, the instructor will hold a virtual class to review what you learned. At the end of the course, you will return the equipment.

On average, it takes about 24 hours over three weeks to complete this course. In all, there are 13 topics and 12 exercises split between three sections, each completed in one week. To earn 8 Professional Development Hours (PDHs), you must complete each week’s course material for a possible total of 24 PDHs. A link to the certificate will appear on the course page next to each course name once it has been completed.


This course is intended for engineers and technicians who have an understanding of:

  • Boolean, math-based, and IEC 61131-3 logic.
  • Power system topology and architecture.
  • SEL relays, communications methods, and protocols.

Course Outcomes

At the conclusion of this course, students will be able to:

  • Describe the expectations of modern integrated automation communications systems.
  • Describe typical RTAC system applications.
  • Use the RTAC web interface to configure settings, such as user accounts, and for troubleshooting purposes, such as reading status and alarm logs from the RTAC.
  • Use acSELerator RTAC to efficiently manage RTAC settings and perform common operations, such as reading/sending and backing up/restoring settings.
  • Identify and properly configure DNP3, SEL, Modbus, and Mirrored Bits communications protocol application settings.
  • Configure the RTAC to allow engineering access to connected IEDs.
  • Configure the RTAC to accept and provide time synchronization using a variety of methods, such as IRIG-B and the Network Time Protocol.
  • Create user logic programs and functions with the IEC 61131-3 programming language in continuous function chart, structured text, and ladder diagram languages.
  • Manage security and logic settings according to NERC CIP requirements.
  • Configure the RTAC to communicate to either a DNP3- or Modbus-based SCADA system.
  • Configure the RTAC HMI for status and control.
