Scope and Application
The YDEVT-10 type electronic voltage sensor is suitable for the power system with rated frequency of 50Hz and rated voltage of 10kV, supporting the use of outdoor column vacuum circuit breaker and switch cabinet complete sets of equipment. The electronic voltage sensor is used in conjunction with electronic instruments and microcomputer measurement and protection equipment to realize the functions of metering, measurement, protection, zero sequence protection, data transmission and digital detection of charged state. The secondary output is a standard small signal without secondary conversion, and can be directly input to the secondary equipment through A/D conversion,
Meet the needs of smart grid development.
