ANALYSIS OF ELECTRICAL NETWORKS

PREVENTIVE CONTROL, FAULT PREVENTION, ENERGY SAVING

     When it comes to finding the causes of an anomaly, measuring the quality of the voltage is not enough. To control the behavior of an electrical installation, you must be interested in the current, which is much more disturbed than the voltage.  

  The liberalization of the energy market and the increasing use of modern electronic equipment which can pollute distribution, making the quality of the network increasingly important for energy users and distributors.

    The quality of the voltage wave covers the disturbances linked to the shape of the voltage wave delivered by the network, which can alter the functioning of electrical devices connected to the network, or even damage them. Different terms can be used depending on the characteristics of the disturbance: voltage dip, pulse overvoltages, high or low voltages, frequency variations, flicker, harmonic and interharmonic rate, phase imbalance, etc.
