Product Details:

SPE-MXJD Single-Phase Ground F Prevention and Line Selection

Product Application:

The core of the single-phase ground fault management system is suitable for medium voltage distribution networks with neutral points not effectively grounded (not/grounded through arc suppression coil) from 6kV to 35kV. It is used for precise fault line selection, positioning, arc suppression, early warning and recording, solving potential hazards such as arc grounding, high resistance grounding, and ferromagnetic resonance. It covers a wide range of scenarios with high requirements for power supply continuity and, such as public grids, industrial enterprises, transportation and energy, and special zones.

Product Features:

Precise Line Selection: By adopting the large current pulse injection and the parallel medium resistance method, and combining with transient recording and analysis, it thoroughly solves the problems of easy misjudgment and omission in line selection under small current grounding with a stable grounding scene line selection accuracy rate of 100%.

Fast Arc Suppression: By adopting active intervention arc suppression, it quickly converts the arc ground at the fault point into metal grounding at the busbar side, and quickly extinguishes the arc of the fault.

Voltage Monitoring: The device monitors the operating parameters real-time, records events for each fault, and completes recording.
