The LMZC-10 current transformer is specifically designed for gas-insulated switchgear (gas-filled cabinets) applications. It adapts perfectly to their internal structure and operating environments to ensure optimal installation and performance.
It offers flexible rated secondary current options of either 5A or 1A, allowing it to meet the requirements of different power monitoring and protection system configurations.
The unique pass-through design makes the installation process more convenient and is especially suitable for gas cabinets with limited space, effectively saving both installation space and time.
The LMZC-10 has a rated short-time thermal current of 40kA for 2 seconds, which ensures the equipment can safely withstand high current surges during system faults.
It supports multiple accurate limit systems (protection levels) including 10P10, 10P15, and 10P20 to satisfy various safety and stability requirements of different power systems.
The instrument safety factor for measurement is FS < 10, indicating that the device provides high safety and reliability during the measurement process, effectively preventing overload damage to connected instruments.
