Description
Product introduction
The LXK is a high-sensitivity zero-sequence current transformer (ZSCT) designed for ground fault detection and protection in low-voltage (LV) and medium-voltage (MV) power systems. It accurately measures residual current to prevent electrical hazards and improve system reliability.
Key Features
·High Sensitivity– Detects mA to A-level leakage currents for early fault warning
·Wide Frequency Response – Works with 50Hz/60Hz and high-frequency signals (for harmonics monitoring)
·Compact & Lightweight – Easy installation on cables or busbars
·Robust Construction – Resin-encapsulated for moisture & corrosion resistance
·Multiple Output Options –Analog (0-1A/0-5V) or digital (RS485, 4-20mA)
Applications
·Ground fault protection in TN-S, IT, and TT systems
·Leakage current monitoring for solar/wind farms
·Fire prevention (detects insulation degradation
·Industrial motor protection
·Smart grid & energy management systems
