The TZY-NP2000A intelligent neutral line protection device and system are connected to the distribution system by simultaneously connecting the phase line and series neutral line. By detecting the current component of the system in real time, the system generates the required current through the converter circuit and injects it into the distribution system in real time, thereby eliminating the current in the neutral line. The device itself has anti-interference function, high stability and maintainability. The TZY-NP2000A series products focus on eliminating neutral line current, eliminating fire hazards, and building a solid "firewall" for firefighting.

1. Eliminate neutral line current to prevent accidents.

2. Resolve three-phase imbalance, improve power quality, and increase power consumption coefficient.

3. Equipped with a protective device, the maintenance system does not require power outage. The parallel live wire mode is in normal working condition, and the series neutral wire mode is backup, with alarm function.

4. Diversified functions can be freely selected according to needs, such as alarm module, system data module, remote communication module, and backup module.
