SGVF series PD free large electronic power source is a set of AC power source which can adjust the output voltage and output frequency. It is mainly designed for the power requirement of the routine test and on-site test upon the transformer, reactor, instrument transformer etc. It is an ideal product to replace the traditional motor generator sets in those tests. Moreover, this unit can be used as power source with transient protection function for the AC test transformer and AC resonant system , so as to replace those voltage regulator and linear frequency converter.
SGVF series can provide the capacity of 500kVA~6000kVA, with output voltage of 0.69kV~10kV and its output frequency of 50Hz ~200Hz ( 0.1Hz~250Hz can be special requirement). The unit is single/three phase output , with good partial discharge (<10pC, special requirement can be <5pC), and its THD <3%.
