With 4-quadrant power simulators we can simulate a NN AC electricity network with powers up to 210 kVA. Different converters can be connected to them, such as diffuse sources, car charging stations, battery power savers, etc. We dispose of two simulators that can be connected in parallel or in series, which enables an increase in power or voltage. Tested devices which are connected to the power simulator can transmit or receive energy and simulators can simulate various anomalies appearing in the electricity network, such as interruptions, voltage peaks, harmonics, DC component, etc. Simulators can change the impedance of the electricity network that is being simulated. This way, converters can be tested across the entire range of operation as well as the immunity of converters to grid anomalies. Regenerative battery power tester can test all batteries with voltages from 60V to 1000V and power up to 120 kW. The battery can be charged or discharged, driven along the desired trajectory. This way, we can obtain real data on power battery energy storage systems. At the same time, the battery tester is also a battery simulator. This is useful when testing converters, because we can set arbitrary voltages and characteristics of the simulated battery. The temperature chamber with a temperature range between –40°C and +130°C and internal dimensions 2.5 m in length, 2 m in width and 2 m in height enables testing of various el. appliances, converters, battery packs, etc. over a very wide temperature range and in extreme temperatures for a long time. The thermal power of the cooling and heating unit is 38 kW. Power cables for AC voltage 300 A and separately DC for 300 A with all related protection systems are run into the temperature chamber. This way, it is possible to connect the test subject with all the above-mentioned devices. The chamber includes a thermal-imaging camera and a high-resolution camera for visual control from the laboratory. The chamber has all required sensor systems. The battery storage system with lithium-titanium-oxide (LTO) cells ensures superior performance. The storage system has a rated voltage of 770 V and can store up to 70 kWh of energy. DC capability 300 A permanently amounts to 230 kW at rated voltage. AC capability of related converters 100 kW permanently. The battery energy storage system enables power supply of DC-DC or DC-AC converters, with voltages from 24 V to 890 V. Related bidirectional converters enable the study and development of various solutions for electricity network assistance, such as RVF, aRPF, Peak Shaving, isolated operation, etc. (name of the device: Toshiba SCiB LTO) 56-channel measuring system for simultaneous capture of the measured quantities with a recording speed of 1 Ms/s and a resolution of 16 bit. It includes 21 voltage inputs up to 1000 V and 32 low-voltage inputs for the connection of various sensors, such as current transformers and inputs for measuring temperature. The system enables simultaneous data capture on a large number of channels with high resolution also over a longer period of time. We also dispose of a larger number of current transformers with high resolution for 400 A, 1000 A and 60 A. The NovaCor digital simulator is a high-performance system for simulations of electricity networks and power electronics in real time and close loop. Possible are also simulations of a three-phase network with up to 200 nodes with a step of 50 microseconds, while the operation of power electronics devices (e.g. VSI, STATCOM, SSSC) is simulated with a step of 1 to 4 microseconds. The hardware includes digital and analogue input and output cards, cards for the synchronization of the simulation step with the external reference (e.g. GPS watch) and a network communication card with embedded software with licences for various standard protocols (e.g. IEC 61850, IEEE C37.118, IEC 60870-5-104). |

The vector network analyzer, the spectrum analyzer and the signal generator enable work in the field of high-frequency signals up to 140 GHz. The vector network analyzer with four ports enables measurement and analysis of impedance parameters and their frequency courses of the magnitude and phase on the most demanding high-frequency circuits. The spectrum analyzer is a great solution when it comes to monitoring the high-frequency spectrum with high sensitivity of up to -153 dBm and a bandwidth of up to 10 Mhz, whereby numerous software extensions ensure the analysis of modular high-frequency signals in the IQ domain from simple modulation schemes to the most demanding communication standards, including measurements of electromagnetic compatibility. What is more, the vector signal generator with a bandwidth of up to 2 Ghz ensures the generation of high-frequency signals in the IQ domain from simple modulation schemes to the most demanding software defined modulation schemes, including the already established communication standards. The generator enables the generation of high-frequency signals following two separate modulation paths with the aim of analysing complex communication systems. |

The set of sensors is intended for monitoring the course of chemical and biochemical reactions. Immediate information on the course of reactions enables better knowledge, quantification efficiency, optimization and scale-up of the process. ReactIR 702L enables studying reactions in real time and thus provides very precise information on initiation, metabolism, kinetics, mechanism and course of the reaction. With in-situ ReactIR 702L we directly monitor the concentration of key reaction components that are changing during the reaction. It provides fast quantitative chemical analysis of batch and continuous processes. It allows real time monitoring of structural characteristics of reaction components with characteristic functional groups. With the in-situ M400 sensor for CO₂ we can precisely measure and control the concentration of the dissolved CO2 in real time, which is significant for bioprocesses. The probe for dissolved CO2 enables us to monitor the dissolved CO2 values for production control and to ensure the desired product as well as maximize the output. Sensors for measuring conductivity are used for controlling the quality of laboratory and industrial manufacturing processes. Conductivity is one of the key physical properties of solutions by means of which we are monitoring the concentration of reaction components. |

The TGA – DTA system for clean samples (TGA 2 + DSC 3) is consisting of two appliances connected to the same processor and the same software, therefore, the obtained results represent a meaningful whole. Thermal analysis is part of basic characterization procedures in inorganic and coordination chemistry as well as in materials chemistry (inorganic nanomaterials, polymers, textile materials). The basic principle of each thermal analysis is the measurement of one or more physical properties of the sample (mass, temperature, dimensions, optical properties), dependent on temperature. In thermogravimetric analysis (TGA) we monitor the mass dependent on temperature and in differential dynamic calorimetry (DSC) we measure the heat flow necessary for temperature equalization between the sample and the inert reference. |

The SurPASS 3 electrokinetic analyzer is an instrument for high quality analysis of the zeta potential on the surface of solids that operates on the principle of measuring the flow potential or rate. The working configuration for the SurPASS 3 instrument is composed of the basic instrument with integrated automated titration unit, a set of Ag/AgCl electrodes, pH electrode, electrode for measuring conductivity, set of measuring cells for various types of samples as well as software. The SurPASS 3 electrokinetic analyzer enables fully automated analysis of the zeta potential of macroscopic solid surfaces in real life conditions. The zeta or electrokinetic potential carries the information on electrokinetic properties of the surface, which means that it provides information on surface charge and on the interaction of surface with electrolyte solution. The instrument is based on the method of measuring the flow potential or rate for direct determination of the zeta potential on the surface where the pressure difference is the driving force. When we create a certain pressure difference in the solution along the charged surface, the solution starts to move alongside the surface and an electric field is created. Because of the tendency to reach steady-state, the created difference in the electric potential causes the flow of excess ions in the opposite direction of the solution volume flow. The created potential difference is called the flow potential and usually amounts to a couple of 10 mV. The flow potential/rate serves for determining the zeta potential according to relevant formulas. |
