The laboratory is specialised in the measurement and analysis of electromagnetic disturbances.
The electromagnetic measurements (EMC) are performed both in indoor and outdoor air conditions.
Pre-compliance measurements for equipment are performed (for example, for getting CE marking), which must meet the electromagnetic compatibility (EMC) requirements set out in European directives.
We perform high voltage electrical equipment reliability and insulation coordination research, also high voltage testing. We have at our disposal an impulse voltage generator with an output voltage up to 800 kV and a cascade transformer supplying up to 300 kV AC voltage (50 Hz).
We work with distribution and transmission utilities, electrical grid construction companies and manufacturers and retailers of electrical equipment. We also conduct lectures on high voltage and electrical safety with demonstrative flashover tests for interested audiences.
The following tests are possible in the laboratory:
- Lightning and switching impulse voltage tests up to 800 kV;
- High voltage AC tests (50 Hz) up to 300 kV;
- Measurement of partial discharges in power cables and insulators etc. using AC voltage in laboratory and with damped AC (DAC) devices in the field;

Autonomous robotics systems, robot perception and navigation systems and respective simulation systems development.
In power electronics laboratory is possible to research, develop, build and evaluate power semiconductor converters.
There are the loads and power supplies for ac and dc applications with power up to 10 kW. To simulate AC grids and conduct the research in the field of grid-tied power electronic devices AC power supplies and loads can be used (1x230 V AC, 5 kW or 3x400 V AC, 12kW).
To simulate PV panels with power up to 500W or PV panel strings with output power up to 15 kW a power electronics solaar panel simulator can be used. For research in the field of DC powered devices programmable 3kW DC power supplies with output voltage up to 600 V DC can be used.
Besides the loads and power supplies is power electronics laboratory also equipped with devices for precise measurement of voltage, current, energy qulaity, temperature, capacitance, inductance etc.
The Power Systems Laboratory examines topics related to the analysis and management of the power system.
The work in the laboratory is mainly focused on:
- analysis and control of power system operation;
- research into wide-area monitoring possibilities;
- research on relay protection and automation settings;
- development of power system operation controllers and power station controllers.
The Laboratory is equipped with world-class equipment such as RTDS Real-Time Simulator, Omicron CMC 256 Plus, CMS356, PMUs from different manufacturers (SEL, Arbiter, Qualitrol, ABB) and various relays (Siemens, ABB, Toshiba).
Lab keywords: substation information systems, relay protection, digitalization of energy systems and cyber defense.
With the equipment in the laboratory, is essentially possible to simulate the operation of a real substation and to see how to detect and prevent faults in the electrical system. The lab has a new generation of Siemens equipment that is used in substations in real electrical systems. In essence, the lab has one real substation that includes relay and automation equipment and the associated communication system. The latter includes operational management solutions from the SCADA system, the remote terminal unit and the switch solution. Communication protocols use all of the current solutions (IEC 61850, IEC 60870-5-104).
From the technical point of view, this is a modular solution and we can connect additional devices and more. The devices are compatible with our existing Real-Time Simulator (RTDS) device, which allows us to create electrical systems and simulate various interference in them, and thus test the behavior and capability of real devices. Thus, the real-time simulator and the new relay laboratory form a whole that can be used to study any issues related to relay protection and automation in the electrical system (seen from both transmission networks and distribution networks).
The laboratory is located in the energetics building (room NRG-527) in Tallinn University of Technology. The laboratory was opened on 28th of November in 2018 and the development of the laboratory was supported by Siemens and Harju Elekter.
