The principle of current transformer is based on the principle of electromagnetic induction. The current transformer consists of a closed core and winding. The number of turns in its primary winding is very small, and the series is in the line that needs to measure the current, so it often has the entire current of the line flowing, and the number of turns in the secondary winding is relatively large, and the series is connected in the measuring instrument and the protection loop.
The performance of products is conformed to IEC61869-1:2007, IEC61869-2:2012 commission requirements
Rated insulation level: 12/42/75kV
Power factor of load: COSΦ=0.8
Rated frequency: 50Hz, 60Hz
Rated secondary current: 5A or 1A
The primary winding, ring iron core and ring coil of this type of transformer are all enclosed in epoxy resin poured insulator, which is a fully enclosed pillar structure with excellent insulation performance and moisture-proof ability, and can operate normally under wet or surface condensation and secondary pollution conditions. It is characterized by high dynamic and thermal stability multiple, large secondary output capacity, higher accuracy system than similar products, and stable insulation performance.
