NettetThe shunt reactors are constructed in the same way as power transformers, with one difference—non-magnetic gaps between the packets of reactor core steel. In 3-phase systems, 3-limbed and 5-limbed core reactors are used alternatively. The neutral of these reactors can be left unearthed, directly earthed, or earthed through the earthing reactor. Nettet30. nov. 2024 · Shunt reactors are classified into two types based on construction: dry type and oil immersed. Dry Type Shunt Reactor. Dry-type shunt reactor is normally limited to 34.5 kV of voltage. This voltage is normally given to the third winding of a transformer & is connected to the compensated transmission line.
