NADQ Series Automatic Capacitance Bridge / Inductance / Current Tester Product introduction At present, mostpower distribution system is generally not neutral point directly grounded , so when the line is single- phase ground fault current flowing through the actual line toground 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, whenelectricity Statutes 10kV and 35kV system when the capacitor current is greater ...
