Particle trajectories in double toroidal coil magnetic field.
A new electric digital energy meter. It is a precursor of Z - D technique. Detector for low voltage signal in the range of 55 - 80 Hz in presence of large 50 Hz signal by zero crossing technique go with the use of a microprocessor. Liquid cristal voltage monitoring for GIS located in the insulator body. Number of publication 100 A book on electric measurement has been edited in Italian ed.
