1、 Overview (Description)
The JENJH8-66W series electronic voltage transformer is an insulated grease sealed fully enclosed product, suitable for use in power systems with a rated frequency of 50Hz or 60Hz and a rated voltage of 66kV where the neutral point is effectively grounded. It is used for energy metering, voltage monitoring, and relay protection. This product complies with the standards of IEC60044-7:1999 and GB/T20840.7-2007 "Electronic Voltage Transformers".


3、 Structure Introduction (Construction)
The JENJH8-66W series electronic voltage transformer is a fully enclosed pillar structure that adopts the principle of capacitive voltage division. The external insulation is a silicone rubber outer sheath and umbrella skirt, which has the characteristics of arc resistance, UV resistance, aging resistance, long service life, pollution resistance, and moisture resistance. It is suitable for installation in any position and direction. The measurement range is wide, and there will be no strong current generated during secondary short circuit. The secondary output is a small voltage signal, with minimal power consumption. There is no need to convert large signals into small signals, simplifying the error source and improving the stability and accuracy of the entire system.

4、 Technical data
