High Precise Current Transforme

LMZT-10 current transformer is suitable to be installed on the special inflatable cabinet for the measurement and protection of current and zero sequence current. It can also be used for the measurement and protection of zero sequence current of multiple cable circuit. The iron core and secondary winding of this series of current transformers are vacuum-cast with high quality epoxy resin in a  flame-retardant plastic housing, which is moisture-proof, stable and maintenance free.

The open-close current transformer is mainly used for cables and copper bars. It has simple structure, reasonable design and flexible application. According to the specifications of the copper bars used in the main circuit, there are many kinds of through holes corresponding to each other. The primary current of the main circuit includes 50A ~6000A, and the rated secondary output current is 1A~5A (0~1V). This series of products can meet the technical requirements of grade 0.2, grade 0.5, grade 1 and other different precision GB/T20840.1.2. 

The open-closed current transformer is improved on the basis of the traditional transformer. Made of free opening and closing, it can be quickly installed and disassembled in the state of no power failure and no wire disassembly, and the operation is sample. The measuring range of this series of products is wide, the rated primary current range 5~630A, the rated secondary current range 0~5A, the current ratio range can reach 500:1~ 10 000:1, the orderly production process flow, to ensure its accuracy level, reliability and other technical requirements. This products complies with GB/T20840.1.2 Standard. 

The product is perforated input single-channel DC leakage current isolated transmitter. The measured DC current signal is isolated by a high-precision isolation device, and the output is linear 0~5V,0~10V, 0~20mA,4~20mA and other standard signals. It is widely used in power supply equipment, power grid monitoring, industrial control monitoring system, railway signal system and other industries.
