Metrology

In the field of metrology, stabilities—of current and voltage, as well as the phase behavior—are the most important criteria.



Creation of traceable sizes also for high-voltage networks

HERO®power has earned an excellent reputation at well-known national metrology institutes such as the PTB (Federal Institute for Metrology), VSM (Dutch Metrology Institute) through power amplifiers to create traceable quantities for current, voltage and power.

Main featur es:

  • 100% loss-performance-proof for inductive loads
  • Phase delay better 100ns (nanoseconds!)
  • Control: local / remote switchable

 

Calibration of high current transformers

Main features:

  • e.g. 100kHz harmonics at 600Arms
  • on fundamental waves, e.g. DC can be modulated up to kA
  • Control: local / remote switchable
