Outdoor Oil Immersed Dead Tank Current Transformer is a type of current transformer in which both the core and secondary windings of the transformer are placed in the bottom tank. This bottom tank is then earthed to make it dead, and hence the name dead tank transformer. In Dead Tank CTs, the primary winding is made to pass through an insulator constructed of porcelain material. It is then connected to the bottom tank and insulated from the tank and the cores of the transformer. The internal design of Dead Tank Current Transformers ensure the primary conductor produces maximum mechanical force during short time dynamic current to prevent damage to internal insulation. Outdoor oil immersed dead tank current transformer is also known as outdoor oil filled current transformer. Both have same functionalities.

The biggest advantage of Oil Filled Dead Tank Current Transformers in comparison to Live Tank Current transformer is its high seismic strength. Since the core and secondary windings are place in the lower tank, the stability of Dead tank CTS is much stronger. Also, it is easier to transport them from the place of manufacturing to the place of installation with lesser chances of breakage or damage. Dead Tank Oil Filled Current transformers are however expensive and heavy compared to Live tank current transformers.

Macroplast manufactures outdoor oil filled dead tank current transformer of various system voltages. In our Dead tank CT design, the cores, primary and secondary windings are arranged in the lower tank. The primary windings are taken to the top tank through HT insulators and connected to the primary terminals. The secondary windings are connected to the secondary terminals arranged inside the secondary terminal box placed on the bottom tank.

The Dead Tank design is preferred where the No. of CT Cores are more because more cores means more weight and lesser stability. In such cases, Live Tank CTs are not preferred from Technical Point of view.
