LVZW-35 Current Transformer

Electrical isolation: The current transformer can effectively isolate the primary circuit of high voltage and high current from the secondary measurement and protection circuit of low voltage and low current, avoiding direct contact of operators with high voltage current, greatly reducing the risk of electric shock, and ensuring the safety of personnel.

Strong anti-interference: Its working principle is based on electromagnetic induction, which will not affect and interfere with the measured circuit, ensuring the accuracy and reliability of the measurement results, and can work stably in a complex electrical environment, providing a strong guarantee for the safe operation of the power system.

The output signal accuracy can reach 0.5, 0.2 or even higher, which can meet the application occasions with high requirements for current signal accuracy. Whether in the normal operation state of the power system or in the transient process when a fault occurs, the current can be accurately measured to provide accurate data support for relay protection, metering, monitoring, etc.

It can be applied to different voltage and current levels, and can meet the needs of various power systems and industrial application scenarios. Modern current transformers usually have a multi-speed adjustable measurement range. By adjusting the transformer ratio, it can adapt to current measurements of different sizes, and has strong versatility and flexibility.

Made of insulating materials and fine wires, it has a compact overall structure, small size, light weight, and is easy to install and maintain. In electrical equipment with limited space, such as switch cabinets, distribution boxes, etc., current transformers can be easily installed without bringing too much burden to the equipment or taking up too much space.

It can respond to current changes quickly and accurately, has good frequency response and dynamic characteristics, and is suitable for application scenarios with a large current change range and high waveform requirements, such as short-circuit fault detection and protection in power systems. When a short-circuit fault occurs, the current transformer can quickly and accurately reflect the size and change of the fault current, providing a reliable signal for the rapid action of the protection device.

The current transformer consumes very little energy when working, and almost no additional load is caused to the circuit being measured. This enables the current transformer to maintain stable performance during long-term use, reducing energy consumption and the impact on the power system.

The current transformer can convert large current into standard small current signals (such as 5A or 1A), unifying the specifications of secondary instruments, relays and other equipment, which is conducive to the standardized design and production of these equipment, reducing the production cost and maintenance difficulty of the equipment.

The standard signal output by it is easy to connect with various automatic monitoring and control systems, and can realize remote monitoring and automatic control of power systems and industrial equipment, improving the intelligence level and operation management efficiency of the system.
