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;
  • Measurement of insulation resistance (transformers, motors, generators, cables etc.) in the range of 50…5000 V DC, detecting resistance values up to 10 TOhm;
  • Measurement of oil dielectric strength with voltages up to 60 kV using different types of electrodes (spherical, cylindrical and “mushroom”).

It is possible to carry out various tests on electrical machines with a capacity up to 50 kW machines in the Electrical Machines Laboratory. In the laboratory, there are equipment for measuring various electrical, mechanical, thermal and magnetic parameters. There are drive units for controlling asynchronous, synchronous and reluctance machines. In the laboratory, there is 80 cm wind tunnel (wind <20m/s) for monitoring various cooling conditions and a diagnostic park for fault monitoring of asynchronous and permanent magnet machines.

The calorimetric test complex of electrical machines is under construction.

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.
