China Energy Construction All Optical Fiber Current Transformer successfully passed the performance test

China Energy Construction has passed temperature compensation test, full temperature test, high temperature aging test, EMC electrostatic test, composite error and small current test
.
Recently, the prototype of the all-fiber current transformer developed by China Energy Construction Group Co.
, Ltd.
successfully passed all key performance tests, and the product performance was better than the relevant standard requirements
of the State Grid.

The all-optical fiber current transformer is a key transformation and upgrading product of China Energy Construction Hunan Electric Ceramic Electrical Factory, and will be gradually applied to the new construction and transformation of substations of
110kV and above.

The test results of the all-fiber current transformer show that the performance indicators are better than the relevant national standards and meet the requirements
of the latest test standards of the power grid company.

All-fiber current transformer is a key equipment in the construction of smart grid, which is mainly used for current signal detection, relay protection, control and monitoring
in power system.
Compared with conventional products, the equipment has the advantages of strong anti-electromagnetic interference ability and simple maintenance, and is the key product
promoted in China's "Optical Fiber Industry 'Twelfth Five-Year Plan'".
