Product introduction
At present, most?power distribution system is generally not neutral point directly grounded , so when the line is single-phaseground faultcurrent flowing through the actual line to?ground capacitance is the capacitance current. According to statistics, the distribution network failure is largely due tolinesingle-phase ground whenthe capacitor is too large to be caused by self- interest arc . Thus, when?electricity Statutes 10kV and 35kV system when the capacitor current is greater than 30Aand10A, respectively , shall beequipped with arc suppression coil to compensate for capacitive current , which requires current distribution network capacitance measurements to make a decision.Inaddition, the distribution networkto ground capacitance and the PT will generate parameter with PT error over-voltage , in order to verify that the distribution system will occur and what thenatureof PT resonance resonance , it mustaccurately measure the distribution network for ground capacitance value. The traditional distribution network capacitive current measurement methodsaresingle-phase metal grounding direct method ,plus capacitance indirect measurement method, etc. These methods have come into contact with one device , so there is danger test , operate complex,efficient and low defects . NADQ series AutomaticCapacitance Bridge / Inductance / Current Tester, directly from the secondary side of the PT measuring capacitive current distribution network,compared with traditional testing methods , NADQ seriesAutomatic Capacitance Bridge / Inductance / Current Tester and one side without dealing with , which is not there is the risk of trial,without doing complicated security measures and wait for lengthyscheduling order , simply measuring line connected to the open delta PT clients can measure the capacitive current data .Triangularopenings due from the PT was injected at different frequency testsignal weak , so neither will relay protection and PT itself, have any impact , but also to avoid the 50Hz powerfrequencyinterference signals, while the output of the tester can be resistant to by100V AC voltage , if the measurement system is single-phase ground fault occurs , will not damage the PT andtester,eliminating the need to make special security measures to make this work to becomesafe, simple , fast, and accurate test results , stable and reliable.
