Product Overview

 Double Cable Cores Type CT LDS235 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

• Adaptive Temperature Sensing Compensation Technology：Equipped with high-precision temperature sensors and intelligent compensation chips, it monitors real-time environmental and winding temperature changes. When temperature fluctuates, it automatically adjusts measurement parameters to ensure measurement error remains within ±0.3% across the extreme range of -40°C to +120°C, effectively solving accuracy degradation caused by temperature drift in traditional transformers.
• Dual Redundant Winding Design：Adopts a primary-backup dual-winding structure. The primary winding undertakes high-precision metering and protection tasks during normal operation; when the primary winding encounters anomalies (such as short circuits or open circuits), the system switches to the backup winding within 5ms, continuously providing reliable current signals and significantly enhancing power system fault tolerance and continuity.
• Integrated Wireless Communication Function：Supports Bluetooth 5.0 and LoRa wireless transmission protocols for fast data transfer without cabling. Maintenance personnel can remotely read current data, calibrate parameters, and obtain device health status reports via mobile apps or portable terminals, significantly improving inspection efficiency and intelligent operation and maintenance.
• Fault Early Warning Self-Learning Algorithm：Built-in AI algorithm module analyzes historical current data and operation parameters to establish device operation status models. It can predict potential faults (such as core overheating or insulation aging) 72 hours in advance and proactively push warning messages, helping users take timely actions to reduce unplanned power outage risks.
