The reason why the secondary side is not allowed to open when the Electrical Current Transformer is running

⒈Electrical Current Transformer Once the measured current, the magnetic potential I1N1 causes the magnetic flux Φ1 in the transformer core

⒉Electrical Current Transformer secondary detection instrument current and magnetic potential I2N2 cause magnetic flux Φ2 in the transformer core

⒊Electrical Current Transformer transformer core combined magnetic flux: Φ=Φ1+Φ2

⒋Since the azimuth of Φ1.Φ2 is reversed, the dimensions are the same, and they offset each other, so Φ=0

⒌If the secondary lead, that is, I2=0, then: Φ=Φ1, the magnetic flux of the iron core of the Electrical Current Transformer is very strong, saturated, the iron core is hot, the insulating layer is burned, and the electricity is lost.

⒍If the secondary lead, that is, I2=0, then: Φ=Φ1, a high induced current potential difference e occurs in the secondary electromagnetic coil N2 of the Electrical Current Transformer, and high voltage is generated on both sides of the secondary electromagnetic coil of the Electrical Current Transformer , Which seriously endangers the personal safety of the working staff

⒎The grounding device at one end of the secondary electromagnetic coil of the Electrical Current Transformer is a safeguard measure adopted to better avoid the danger of high voltage.
