The OMICRON CMC 256 is a high-precision test instrument with which various protective relays such as electromechanical, static or numerical can be checked. Due to its high accuracy, it can also be used as a calibrator.
Test equipment for earthing and overhead line systems
For example, the OMICRON CPC 100 and the associated OMICRON CP CU1 matching transformer can be used to measure the impedance of cables and overhead lines, earth impedances as well as on-site voltage and contact voltages.
The Institute of Electrical Power Systems of Graz University of Technology has measurements available for on-site measurements and, for training purposes, the following installation testers for testing protective devices in low-voltage systems:
GOSSEN METRAWATT PROFITEST MTECH
CHAUVIN ARNOUX C.A 6115
In addition, the institute has the following measuring equipment for checking the electrical insulation:
With the mobile, multiple existing modular data acquisition systems from DEWETRON, up to 32 signals can be recorded with each device and evaluated on site. The system includes, among others:
DEWETRON DEWE-30-16 (Expansion rack)
DEWETRON ELOG-550 (Energy Data Logger)
DEWETRON ELOG-570 (Power Network Analyzer)
DEWETRON DEWECLOCK (GPS watch)
With the help of this measuring system voltages can be recorded directly and currents via external peripheral devices such as current clamps or Rogowski coils. The assortment of existing current clamps ranges from a nominal current of 5 A to 1000 A. Measurements of up to 1 kA can be carried out with the Rogowski coils with an integrated measuring amplifier with arrangements whose circumference does not exceed 5 m.
Weather station (pyranometer with temperature sensor) and long-term data recording
With many measuring tasks it is necessary to measure the weather conditions with it. For this purpose, the institute owns the measuring system of Delta-T Devices
the SPN1 pyranometer and the
GP2 Data Logger as well as the EML SS1 sensor protection
to protect the temperature sensor from solar radiation, precipitation and wind. With the aid of this measuring system, it is possible to detect the global radiation consisting of the horizontal radiation and diffuse radiation as well as the ambient temperature over a longer period of time (for example a full calendar year).
