Product introduction

At present, most power distribution system is generally not neutral point directly grounded , so when the line is single- phase ground fault current flowing through the actual line to ground capacitance is the capacitance current. According to statistics, the distribution network failure is largely due to line single-phase ground when the 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 30A and 10A, respectively , shall be equipped with arc suppression coil to compensate for capacitive current , which requires current distribution network capacitance measurements to make a decision. In addition, the distribution network to 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 the nature of PT resonance resonance , it must accurately measure the distribution network for ground capacitance value. The traditional distribution network capacitive current measurement methods are single-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 Automatic Capacitance Bridge / Inductance / Current Tester, directly from the secondary side of the PT measuring capacitive current distribution network , compared with traditional testing methods , NADQ series Automatic 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 lengthy scheduling order , simply measuring line connected to the open delta PT clients can measure the capacitive current data . Triangular openings due from the PT was injected at different frequency test signal weak , so neither will relay protection and PT itself, have any impact , but also to avoid the 50Hz power frequency interference signals, while the output of the tester can be resistant to by 100V AC voltage , if the measurement system is single-phase ground fault occurs , will not damage the PT and tester, eliminating the need to make special security measures to make this work to become safe, simple , fast, and accurate test results , stable and reliable.
