Outdoor Oil Minimum Immersed Current Transformer

oil minimum current transformer

Outdoor oil minimum immersed current transformer is a unique current transformer design developed in-house by Macroplast. These type of CT design has only one tank which reduces the requirement of oil in manufacturing the transformer. This in turn reduces the cost of producing the transformer. Oil minimum CTs are cheaper than both live tank CTs and dead tank CTs

In this design, the cores and primary windings are taken through porcelain insulators and connected to primary terminals. Unlike other Current transformers, this design has two porcelain insulators for incoming and outgoing conductors. The LT terminal box is also attached on the body of the tank. Oil minimum current transformers are usually used in lower system voltages power systems upto 33 Kilovolts (KV).

Macroplast manufactures Outdoor oil minimum current transformer upto 33kv system voltage. Our outdoor oil minimum current transformers are widely used by several state electrical utilities, private industries and sub-station turkey contractors in India.

Oil Minimum Current Transformers are preferred where the primary currents are not more than 400 A and the CT Cores are also less maximum to 2. Primary currents more than 400 A will lead to manufacturing problems and is not feasible from technical point of view.
