Session 2: Relay Testing Automation
Nowadays the protection engineers face complex multi-functional relays with advanced intelligent functions, rather than simple basic single-function relays. This has also increased the level of complexity of the testing process. The automated testing template is essential for minimizing the effort and duration needed.

Session 3: System-based Protection Testing
In addition to conventional testing methods, such as parameter-based testing, a system-based approach is the most efficient way to detect hidden errors in the settings, logic, and design of the protection system. This allows testers to verify the correct behavior of their protection system faster and with higher test quality than ever before.

Session 4: Distance & Differential Protection
Distance relays are applied as the main short-circuit protection in almost all systems where the overcurrent relays cannot be used due to its protection selectivity. Distance protection is used to protect a line as main protection. If a fault occurs within the protected area the protection relay calculates the short circuit impedance by using measured voltages and currents.
The most important components in power transmission and distribution system are transformers, generators and busbars. Differential relays are applied as their main protection against short-circuit faults within the protected area.
The purpose of this session is to explain the principles of these two protection functions and further illustrate the testing solutions with OMICRON Test Universe and RelaySimTest.

Session 6: Impact of CT/VT to the Protection and Measurement Systems
A lot of protection functions are using current as the protection criterion for its operation. Most relays are connected to conventional CTs with iron cores. If the magnetic force increases (caused by a current), more and more molecular magnets will be arranged in the same direction. As soon as all molecular magnets are arranged into the same direction the magnetization reaches its limit and the iron core of the CT will be saturated. To test the protection relay thoroughly, protection engineers also need to consider how CT saturation affects the performance of the relay.
On the other hand, correct metering of energy is important to energy generation and distribution utilities. The instrument transformers (CTs and VTs) contribute to the accuracy of the overall system. They need to be properly tested and calibrated in order to ensure high overall accuracy. It also plays an important role for the protection system.

Session 7: Data Management and Time Grading
Proper asset tests and regular maintenance are essential for keeping protection systems in good working order. In addition, quick access to relevant test documents is indispensable for efficient planning and providing proof when requested. Proper data management ensures that the workflows of asset and operation managers, testers, and protection engineers are structured and coordinated.

Session 8: Renewable Energy
The rapid increase in renewable energy sources is creating additional workloads for both transmission and distribution networks. Challenges that can be overcome with the help of Smart Grids. By increasing the availability of the power supply and providing a clear overview, digitized secondary substations have an important contribution to make.
