処する手段か望まれているという課題があった。The conventional three-phase lump-type gas-insulated switchgear instrument transformer is
Because the three phases mentioned above are housed in the same grounded metal container (this is housed in the same grounded metal container), even though the main circuit current value for each -phase should be detected accurately, #L is affected by magnetic flux caused by current disturbance, or after the high voltage center conductor of the own phase passes through the relevant instrument current transformer.
If the curved path is changed to the right angle direction so that it is tangent to +14, there is a problem that ζ is affected by the magnetic flux of the own phase that does not contribute to detection, and therefore a detection error occurs.Is there a way to deal with this problem? There was an issue of being desired.
