RSPDF-1000 Relay Protection Device DC Ground Fault Tester
PDF1000 type DC ground fault tester is a new generation of products. It can be applied to DC systems of any voltage class and is equipped with high- accuracy test clamp meter, greatly improving the test range and anti-interference capacity through efficient processing of various signals; It adopts outstanding algorithm and advanced fuzzy control computation theory and displays the advantage degree of tested insulation branch in the form of figure, fully embodying the superiority of artificial intelligence; For the determination of ground point location, it also has accurate judgment and can point out the location and direction of ground point in each test.
The DC ground fault tester gives priority to system safety and carries out test according to the highest requirements of the industry standards by means of reliable low frequency signal and also carries out a lot of practical application in the field without effect on the system.
DC system fault tester is used to find out the accurate location of the DC system ground point of the power plant and converting station under uninterrupted power supply. It can quickly find out the ground point of various types of ground faults with 100% accuracy rate.
