(1) The ratio should be appropriate. It should be ensured that the actual load current in normal operation reaches about 60% of the rated value, at least not less than 30%. The actual secondary load is within the rated secondary load range of 25% to 100%, and the power factor of the rated secondary load should be 0.8~1.0 to ensure accurate measurement.
(2) Make sure that the polarity of the primary and secondary sides of the current transformer is correct when wiring. The connecting wires of the secondary circuit of the transformer shall be made of steel single-core insulated wire. For the current secondary circuit, the cross-sectional area of ​​the connecting conductor shall be determined according to the rated secondary load of the current transformer, and shall be at least not less than 4 mm2.
(3) When working on the secondary circuit of the running current transformer, it is forbidden to open the circuit; if it is necessary to replace and calibrate the instrument, first short the circuit in front of it, prohibiting the winding of the copper wire and the current transformer to the short circuit point. Do any work on the loop between.
(4) The secondary side of the current transformer shall have a permanent and reliable grounding point at one end, and the grounding point shall not be disconnected.
