NOVA QA

Class a equipment for monitoring the quality of electricity

The NOVA QA equipment is intended for class A measurement, respectively for monitoring the electrical parameters and phenomena that define in the current context the energy quality, according to the IEC 61000 standard in force.

The NOVA QA equipment allows:

  • measuring and recording the effective value and the maximum value of the voltage on each phase;
  • measuring and recording the effective value of the current on each phase;
  • determination and registration of asymmetries / voltage and current imbalances for the three-phase system;
  • measuring and recording the power factor;
  • frequency measurement and recording;
  • determination and registration of active, reactive, apparent and deforming power;
  • determining and recording the harmonics and inter harmonics of voltage and current, of the harmonic distortion factor;
  • measuring and recording short and long duration interruptions, respectively;
  • measuring and recording voltage gaps;
  • measurement and recording of temporary industrial frequency surges and transient phenomena;
  • measuring and recording voltage fluctuations (fliker level);
  • analyzes and reports according to users’ standards and / or requirements.

The use of NOVA QA equipment, independently or within an integrated electricity quality monitoring system – Smart Grids, ensures the necessary conditions for:

  • improving information support for management, for real-time decision making;
  • creating an overview of the energy saving potential for the user, in the short, medium and long term;
  • reducing the probability of equipment failure, reducing the probability of production losses and interruptions in the power supply;
  • reducing energy costs by automatically tracking consumption, including forecasts and avoiding penalties applied by the energy supplier;
  • reducing energy costs by automatically tracking consumption, including forecasts and avoiding penalties applied by the energy supplier;
  • global business optimization, by reducing energy costs;
  • prevention of equipment failure and / or excessive heating, by controlling the harmonics and keeping them below a certain level, etc.

10 digital inputs: 1 x trigger contact; 1 x trigger contact; 1 x CSA contact; 1 x auxiliary contact A (optional);

The NOVA QA equipment can be easily parameterized according to the specific requirements of each user and can be easily developed / upgraded according to new technical requirements.
