Lumel ND1

Lumel ND1

The ND1 3-phase power analyser is an up-to-date device allowing the user to measure and recording electrical energy quality parameters. It enables to detect interferences in internal industrial electric installations.

PRODUCT HONOURED ON THE MOST IMPORTANT EXPOSITION ENERGETAB, IN BIELSKO-BIAŁA , POLAND. Product received also the prestigious award EUROPEAN MEDAL, which is granted for products, that fulfill legally required standards, appropriate licenses and patents enabling their sale on the European market.

Data recorded by the ND1 analyser provide information for costs control systems and optimization o device operation in power energy installations and industrial systems.


The device design unites in itself the function of 5 instruments:

  • analyser of 3-phase network parameters
  • universal measuring transducer
  • recorder of measuring data
  • web server – possible an easy remote monitoring of measuring and archival
  • data through the internet browser
  • controller – automatic control of electric energy key parameters
