Residual Voltage Transformers (RVTs) are category of instrument transformers which are in electrical systems to protect capacitor banks from earthing faults and prevent damage. The main function of these class of instrument transformers is to detect neutral to ground fault conditions and discharge the capacitor banks as and when required automatically. In an electrical system in normal working conditions, the windings of an RVT will have no voltage output. On the other hand, in the event of an earth fault a voltage will be developed across the open delta winding of the transformer which will activate the relays and cut the power connection thereby protecting the measuring equipments from damage. The function of RVTs is similar to voltage transformers in some areas. However their and utility is different from one another. It is probably one of the reasons why many people consider RVTs as a sub-group of voltage transformers.   Macroplast manufactures Residual Voltage Transformers for varied system voltages. The most common systems voltages are 11 KV, 33 KV system voltages in which five limb core construction is employed instead of conventional three limb construction. The outer two limbs carries the residual flux and the secondary windings are connected in open delta fashion.

Distribution transformer derives its name from its usage in the electricity grid where its function is to step down the electrical voltage in the distribution line to a level that can be used by electricity consumers. Distribution transformers are used by power utilities to distribute electricity to domestic and commercial customers at a voltage that can be used by them for various purposes. Distribution transformers refer to a large family of transformers and includes pole mounted transformer, pad mounted transformer, single phase transformer, three phase transformers and underground transformer. The design, construction and functionality of each of these sub-category of distribution transformers are different from one another. Distribution transformer manufacturers follow their own design and construction features to manufacture distribution transformers. The overall objective is to meet client objective and customize it according to the requirements in the electrical system. Macroplast is amongst the leading names of distribution transformer manufacturers India. We manufacture outdoor ONAN Cooled Distribution Transformers upto 2500 KVA with system voltage of upto 33 KV. In the few years, we have supplied distribution transformers to several state utilities, government bodies, and leading private organizations. We have the right knowledge, years of experience and technical capabilities in distribution transformer manufacturer in India. The key features of our Distribution transformers are: • Stack core surrounded by Primary and Secondary windings housed in a steel tank• Primary and Secondary terminals or studs• High Voltage and Low Voltage Insulators• Off-load tap switch• Silica Gel Breather• Expansion Tank or Conservator• Oil Level Indicator• Thermometer Pocket• Oil Filling Plug• Oil Drain Valve• Arcing Horns

We manufacture outdoor oil immersed potential (voltage) transformer without top expansion tank upto 33kv system voltage. This design has a single tank. The core and windings are contained in the lower tank. The primary winding is taken through the ht insulator to be connected to the primary terminal arranged at the top of the ht insulator. The secondary windings are connected to secondary terminals placed on the lower tank.

Outdoor Oil Immersed Live Tank Current Transformer is a type of electrical current transformer in which the core of the transformer along with its secondary windings is placed in the top tank. They are also known an outdoor oil filled current transformers. Live Tank Current Transformers are different from Dead Tank Current Transformers in their design and tank fabrication. At a macro level, the basic functionality of both remain the same, which is to step down high voltage current to low voltage current for measurement by energy meters or other such instruments. In an outdoor oil immersed live tank current transformer, the core and secondary windings are insulated from high voltage with insulating material and placed in the top tank. In Live Tank CTs, the primary conductor is shorter in length which makes it stronger to withstand high short circuit currents. Also, the primary winding in Live Tank Current transformers is homogeneously distributed around the core to create a current transformer which has low reactance and excellent transient performance. Live Tank Current transformers are smaller and compact in size compared to Dead Tank Current Transformers. They are also more economical to be produced and are hence cheaper than Dead Tank CTs. Macroplast manufactures oil filled live tank Current transformers upto 132 KV system voltage. The Live tanks CTs manufactured by us have cores, primary and secondary windings arranged in the top tank of the transformer body. The primary windings are then connected to the primary terminals which are also arranged in the top tank. The secondary windings are taken through the HT insulator to the bottom mounting base. The mounting base has arrangement for secondary terminals inside the secondary terminal box

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.

Current and potential transformers are usually used as single phase units. However nowadays, combined ct-pt units are the most commonly used variant of current and potential transformers, especially while being used for metering purposes for single or multiple ratios. At times, an additional core is provided too for protection purpose. The combined ct-pt units is used for - 3 phase 3 wire metering system or for 3 phase 4 wire metering system. In case of combined ct-pt units we use a single unit consisting of 23 single phase cts and one 3 phase pt in place of 23 single phase cts and 3 single phase pts.
