We ensure the following services of electrician laboratories:
- diagnostics of insulation sytems of rotary electrical machines, such as hydroalternators, turboalternators and hv motors
- diagnostics of non-rotary electrical machines (power transformers, machine transformers, bushings aso.)
- analysis of insulation oils (including tests of thermally-oxidating stability)
- analysis of machine oils
- determination of PCB material content in oils
- gas-chromatographic analysis of gases dissolved in the insulation oil (extraction by a Toepler exhauster and HEADSPACE method)
- analysis of the SF6 filling (purity, humidity, gas-chromatographic analysis of the dissintegration products)
- measurement of the insulation parametres of switches
- tests of work and protection instruments
- voltage tests of hv machine transformers
- revisions and evaluations of hv and vhv electrical devices
- gauge calibration
- electrical production for electricity engineering, devices for the equipment of distribution points and power plants
- verification and calibration of resistance thermometers, thermo-electrical cells, šestinových cells and standard rezistors
- piece and small-series production in an affiliated mechanical workroom
