Description:
DF901 Automatic 10KV Capacitance & Dissipation Factor Test Set is used to measure dissipation factor (PF) and capacitance of liquid and solid insulator, such as cables, capacitors, line transformers, generators, motors, bushings etc.
Product Features:
This system is suitable for both low and high voltage measurement at line frequency
Whole in one designed: including precision HV digital bridge, reference capacitor internal HV tank, precision SPWM frequency power
High anti-Interference by variable frequency and digital filter technology, the instrument can ensure test accuracy while Interference current is no more than 2 times of the test current.
High accuracy by high precision digital bridge, digital signal process, self-calibrating and other advanced technique together.
Fully Protections, including high voltage protection, input protection and grounding protection.
Multi test modes support, Supports UST (Ungrounded Specimen Test) and GST (Grounded Specimen Test),internal/external reference capacitor (CN) mode, internal/external test voltage selections, it can satisfy all normal dissipation factor test and HV dissipation factor test (more than 10kV, it need an external CN which has more higher voltage level).
Fully automatic operation. When test start , it rises the test HV from zero to set value smoothly, then measures data, and then falls down the output voltage to zero, and then puts to display. If auto-print is selected, the results are printed out.
LCD display operation schedule and test values
External HV & reference capacitor is available
Can work together with Personal computer by RS232
Suit at site or lab, for example, oil dissipation test.
