The LFZB3-10 series current transformer is an epoxy resin cast fully enclosed through wall structure, suitable for measuring current and energy and relay protection in power lines and equipment with a rated voltage of 10kV and below and a rated frequency of 50Hz. The characteristics of this product are small size, light weight, wall penetration installation, and strengthened external insulation. It belongs to the working condition type product and can replace old products such as LA-10. On the basis of LFZB3-10, using the principle of capacitive voltage division, the sensor part of the high-voltage live display device is directly added to the transformer. After adding the sensor, all technical parameters of the transformer are not affected and the volume is not increased. It is the first new generation product in China.
Rated insulation level: 12/42/75KV
Power factor of load: cos Φ=0.8 (lag)
Rated secondary current: 5A (or 1A)
Surface creepage distance: 250mm
