electronic power source

Product Description

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 **0kVA~***0kVA, with output voltage of 0.*9kV~*0kV and its output frequency of *6.6Hz ~**0Hz ( 0.1Hz~**0Hz can be special requirement). The unit is single/three phase output , with good partial discharge (<*0pC, special requirement can be <5pC), and its THD <3%

The various test objects and different test items have different requirement upon the power source. Therefore, the traditional motor generator or the linear frequency converter must pay attention to the power factor in order to match the requirement of linear load or variable load. Even so, some load requirement is unable to be matched by the MG set or frequency converter in such case. On the other side, SGVF series can provide a large range of power factor from *0.*****0.*1 with frequency resolution of 0.*1Hz, which definitely takes over the weakness of traditional MG set. Moreover, SGVF series has the capability of transient feedback and full output current at full output range, which covers the shortage of the linear frequency converter.
