Introduction
The Terminal Electrical Comprehensive Management and Protection System, abbreviated as (NTPS), is an electrical product that detects and analyzes the current of end circuits. Based on the principles of power supply continuity and safety, it manages harmonics and three-phase imbalances, protects precision equipment, eliminates neutral line current, and provides overcurrent quick-break protection, definite-time protection, and inverse-time protection for neutral line overcurrent conditions.
Addressing User Issues
Traditional compensation and management equipment addresses power quality issues at the distribution room and further upstream towards the grid.
There is no targeted equipment to protect the user's internal power consumption systems and devices.
Solving User Pain Points
Neutral line overheating, circuit breaker zero-sequence protection, circuit breaker tripping, cable insulation aging.
Increased line loss, severe three-phase load imbalance...
One-Stop Solution
Eliminate neutral line current + End harmonic protection + Three-phase imbalance regulation + End reactive power compensation.
Backend system, mobile APP, remote viewing, remote control.
Comprehensive Improvement of Power Quality
Reduce electrical fire risk, avoid power outages caused by zero-sequence protection.
Extend cable service life, reduce line losses, lower line current...
