LJ-75 current transformer

Introduce:

This type of zero-sequence current transformer for the rated frequency of 50Hz. the ratedvoltage of 35kV and below the neutral point non-effectively grouded system for the measurment of zero sequence current and earth fault protection.

Mainfeatures:

  • The core of the transformer for the circular ring,and annealed,the secondary winding in two segments around the core on the clamping core cast iron clamp support Transformer clamp,temanal blocks and bolts and four mounting holes.
  • Type transformer primary winding,the three-phase cable through the core window as the primary winding.
  • The window allowed by the largest diameter of the cable is 75mm.

Technical Parameter:

  • With the use of this type of transformer and DL11/0.2 relay.
  • When the transformer secondary winding by DL11/0.2 type braeker 9relay coils connected in parallel .
  • Tuning current of 0.1A)and the transformer secondary external total impedance is not greater than 10 Ω,a residua current of the relay is not greater than 10A
