Product description

Product Description:

The Online Network Impedance Spectrometers for the low-voltage level up to 690 Vrms (ONIS-690V) and the medium-voltage level up to 36 kVrms (ONIS-36kV) can measure the loop and line impedance parameters of single- and three-phase power systems. The power system characteristics are precisely measured time- and frequency-dependent from DC to 50 kHz. We offer on-site measurements to characterize and identify weaknesses in power systems and recommend solutions as experts.
