Optical instrument voltage transducers KRISMARS-VT 

 Power Industry policies of the Russian Federation have given a top priority for the development of Smart Grid concept. In particular, research and design of non-conventional instrument current and voltage transformers for networks 35 to 110 kV is the task of major importance. 

  • The crystal selected as an optical cell material provides high temperature stability of the electro-gyration constant and exhibits no piezoelectric effect, which gives the possibility to create a voltage sensor operating in wide temperature and frequency ranges
  • High measurement accuracy owing to Faraday effect compensation
  • The transducer can also be used for current measurements – the only thing to do is to replace the voltage (electro-gyration) optical cell with the current (Faraday) one
