Calibration high voltage & current measuring equipment (National Lab)

The mission for RISE's High voltage group is to provide state-of-the-art calibrations of measuring equipment used in high voltage and high current testing. Within the high voltage area we have resources for DC and AC line frequency but also for measurements of various waveshapes like peak value, harmonics and high voltage impulses.

Cause

The national laboratories are responsible for maintaining the national reference standards for each measurement quantity and spreading metrological competence and traceability to industry and society at large. The national reference standards are the highest level of traceability in Sweden.

We provide our calibration services both in our own high voltage laboratory and at the customer's site. Our high voltage lab lets us generate and measure up in the megavolt range and allows for parallell activities in several test bays.

  • 18x24x17 m
  • Completely shielded
  • Very low background PD level (<5 pC)
  • Very low background sound level (<40 dB)
  • Controlled climate
  • AC voltage up to 350 kV
  • DC voltage up to1200 kV
  • Lightning and switching voltage impulses up to 2100/1600 kV
  • DC current up to 6 kA

Measurement equipment for high currents and voltages is often both large and heavy. Because of this we have developed world-unique expertise and resources for field measurements, at customer’s premises or in high-voltage installations such as switchyards etc.

Strong personnel group comprising both world-renowned researchers and experienced technicians guarantees competence, flexibility and capacity.

A calibration performed at a national laboratory fulfils all typical traceability and accreditation requirements that commonly exist in industry and society at large. 

Method

Examples of high voltage calibration services:

  • Measuring systems for AC voltage, peak/√2 and r.m.s. (IEC 60060-2)
  • Measuring systems for DC voltage (IEC 60060-2)
  • Measuring system lightning and switching impulse (IEC 60060-2)
  • High voltage capacitors (capacitance and dissipation factor)
  • High voltage AC power loss measuring systems
  • Capacitance and dissipation factor standards and measuring systems
  • Voltage and current transformers
  • Current clamps, Rogowski coils, DC and AC current measuring systems
  • PD calibrators & measuring systems
  • High voltage insulation testers (meggers)
  • Voltage detectors
