Abstract :
A method is discussed for on-line measurements of parameters of a power distribution system and its associated load. Four parameters are measured: the complex impedances of the distribution system and the load for harmonic frequencies; the complex rms (crms) values Jn of the harmonics of the load current j and the crms values En of the harmonics of the distribution system voltage e. The measurements are performed on two states of the system before and after it is disturbed by either connecting to it a capacitor or a harmonic generating device. The results of physical measurements are compared with those calculated from a model
