Product Overview
Zero -Sequence Current transformer LXSC adopts newly high permeability core with high measuring accuracy. Secondary winding fully enclosed vacuum casting in antiflaming plastic shell. It easily installed by making the primary cable through the whole, applied to electrical system cable with highest equipment voltage 0.72, functioning as the tool of current metering , signal collection, relay protection. The current transformer can be executed according to the standard IEC 61869-1:2007 and IEC 61869-2:2012. Or IEC60044-1.
Key Features
High-Precision Current Measurement with Metering-Grade Accuracy：Utilizing high-permeability silicon steel laminations, achieving Class 0.2S accuracy with ≤0.2% ratio error and ≤10' phase displacement across 1%–120% of rated current. Dual secondary outputs (5A/1A) support high-precision metering devices like energy meters and power analyzers, ensuring accurate billing and revenue metering.
Fully Enclosed Epoxy Insulation Structure：Vacuum-cast epoxy resin provides hermetic sealing with IP68 protection, allowing continuous submersion in water. Compliant with UL94 V-0 flame retardancy, it operates reliably from -40°C to +120°C, ideal for harsh environments including coastal salt spray, underground mines, and wet basements. Maintenance-free design ensures lifecycle reliability.
Wide-Range Multi-Tap Design：Covers ratios from 50/5 to 3000/5A with built-in multi-tap windings (e.g., 200/5A, 400/5A, 800/5A), enabling flexible range switching via external links. Dynamic response ratio of 1:150 maintains linearity from normal load (100A) to short-circuit fault (15kA), ensuring accurate measurement across diverse operating conditions.
Anti-Saturation & Fast Transient Response：Special magnetic circuit design prevents core saturation up to 20x rated current. Class 5P20 protection winding delivers ≤10ms response time, supporting overcurrent and differential protection schemes. Effectively safeguards electrical equipment against short-circuit damage and overload conditions.
