These analysers are especially suitable for maintenance & testing services in industrial or commercial plants or in public institutions. They provide an immediate mapping of the most important network parameters & the network quality. The device is handy & accurate & offers many calculation & editing functions in addition. All network parameters, transients, alarma & wave shapes are registered & recorded simultaneously. The real-time display of the inputs is done simultaneously depending upon the requirement in graphic mode, as vector display or as value table. In the expert mode the user can conduct an analysis of the harmonics & study the effect of the harmonics on the heating of the neutral wire or on electrical machines. The C.A 8335 offers in addition a measurement of the in-rush current i.e. the switch-on current of the electrical machines, which is necessary especially for the correct dimensioning of the electrical systems. The measurement duration is more than 1 minute.
