The LZZBJ9-10A1 is a indoor single-phase current transformer (CT) used in electrical power systems for measuring alternating current (AC). Current transformers are essential components in the energy sector, particularly in high-voltage applications, as they provide a scaled-down current that can be used for metering, protection, and control without directly connecting high-voltage circuits to low-voltage measurement devices.

 

 

· High Accuracy: Designed to provide accurate current measurement, crucial for protection and metering in electrical systems.

· Insulation: Epoxy resin casting insulation materials ensure safety and reliability in high-voltage applications.

· Compact Design: Compact and robust design allows for easy installation and integration into various electrical systems.

· Durability: Built to withstand harsh environmental conditions and mechanical stresses.

· Mounting: Designed for easy installation in switchgear, substations, and other electrical distribution systems.

 

 

• Metering: Used in electrical metering systems to provide accurate measurements of current for billing and monitoring purposes.
• Protection: Works in conjunction with protective relays to detect faults and abnormal conditions in the power system, facilitating timely disconnection to prevent damage.
• Control: Provides current feedback to control systems for efficient power distribution and management.
