Scope of application current transformer is mainly used in indoor, for the rated voltage of 0.5kV and below, rated frequency of 50Hz AC circuit as current, electric energy measurement or relay protection. The product is cast type current transformer, using the base plate fixed installation mode..
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 conventional transformer is composed of coil, mounting plate and insulating material (resin casting filler).
In addition to these, the Type II (new) transformer also adds a shell coil which is first installed in the shell and then sealed by resin pouring filler.
Both are dry insulated.
The label of the Type II (new) transformer can either be laser etched on the housing body, or aluminum labels can be inlaid on the housing.
One bus goes through the window.
The transformer is bolted to the mounting plate.
