The core competence of the calibration laboratory of HIGHVOLT Prüftechnik Dresden GmbH is the calibration of electrical measurands, with a focus on high-voltage applications. The calibrations are performed at high DC voltages, AC voltages and impulse voltages. Here, it is not only the high voltages that are measured in the calibration processes; instead, the different types of high voltage also form the boundary conditions for the calibration of associated measurands in the area of high voltage. Measurands include capacitance, dissipation factor, impulse power and AC power.
Accredited calibration laboratory since 1999
 |
The calibration laboratory of HIGHVOLT Prüftechnik Dresden GmbH is accredited by the German Accreditation Body (Deutsche Akkreditierungsstelle, DAkkS) in accordance with ISO/IEC 17025. DAkkS is a signatory of the Multilateral Agreement of the European co-operation for Accreditation (EA), the International Accreditation Forum (IAF) and the International Laboratory Accreditation Cooperation (ILAC) for mutual recognition of calibration certificates.
The calibration laboratory of HIGHVOLT Prüftechnik Dresden GmbH is a member of the German Calibration Service (Deutscher Kalibrierdienst, DKD).

2021
|
Transition to ISO/IEC 17025:2017
|
The transition to the new accreditation standard ISO 17025:2017 has been succesfully finished.
The german tranlation of the ISO 17025:2017 is the DIN EN ISO/IEC 17025:2018. Because the release date of this standard was November 2017, the german translation has been published in 2018.
