Epoxy Resin Cast Potential (Voltage) Transformers are dry type transformers and may be used for indoor and outdoor applications. Their key function is to step down voltage in an electrical system. These class of transformers are manufactured using high quality epoxy resin which is a strong synthetic polymer developed from epoxide chemicals. The scientifically proven insulation properties of epoxy make it an excellent material for manufacturing dry type resin cast potential transformers.

Both the Potential Transformer & Voltage Transformer are the same. The only difference is their names. The technical meaning of the words - Potential or Voltage – refer to the same thing.

Macroplast manufactures epoxy resin cast voltage transformers up to 33 KV system voltage. Our resin cast PTs are are fitted on metering panels or cubicles and in most circumstances used indoors. They may be used for Outdoor applications if they are enclosed either in a sealed metal tank or cubicle. The energy meter or measuring instrument is also placed within the same contraption. Epoxy resin cast voltage transformers can also be used outdoors provided they are enclosed in a hermetically sealed metal tank.

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.

Low Voltage Current transformers may be either Tape Wound or Epoxy Resin Cast. They may be either Ring Type or Wound Primary Type. For lower ratio, high accuracy CTs, Wound Primary Construction is preferred. For higher ratio CTs, Ring Type Construction is preferred from the economical point of view. Ring Type CTs are most economical if the primary current is 200 A or more. For primary currents lower than 200 A, Wound primary CTs are most economical. Low Voltage (LV) or Low Tension (LT) Current Transformers are one and the same thing. These type of transformers are usually insulated with Epoxy Resin or Cotton Tape and are primarily used in electrical systems for metering and protection. The standard secondary output from such transformers are 1 Ampere or 5 Amperes.

Tape wound current transformers are widely used in switch gears, distribution systems, electrical generators, indoor or outdoor control panels and control instruments.

 

Macroplast manufactures Low Voltage Current Transformers of 1, 0.5, 0.2, 0.2s accuracy class. Our LT-CTs are constructed with only a single secondary winding. We possess the expertise to manufacture these either in tape wound or resin cast type depending on client specifications and requirements.

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.

Epoxy Resin Cast Current Transformer is a dry type transformer in which the internal windings and coils of the transformer are coated with epoxy resin for Insulation purpose. It is widely used in instrument transformers where the primary function is to step down high currents and voltage. In an epoxy resin cast current transformer, the windings consist of high quality electrolytic grade copper which are wound around the core and insulated using a layer of fiberglass mat or quartz powder before being cast with an epoxy resin in an automated vacuum casting machine to provide the necessary insulation.

Epoxy is a strong synthetic thermosetting polymer which is made from various epoxide materials. Epoxy is widely used in various industries like adhesive industry, synthetic paints, casting industry amongst others. In the electrical industry, it is primarily used for the process of insulation. Its chemical composition offers excellent insulation properties and is therefore widely used in the transformer industry for making dry type resin cast transformers.

The function of resin cast current transformers are similar to oil filled current transformers. The reasons why some businesses prefer to use it is because they are better in handling moisture, there is no leakage and pilferage of oil, and they are far more compact in size compared to oil filled transformers

Macroplast manufactures epoxy resin cast current transformers up to 33 KV system voltage. These are manufactured using high grade epoxy resin polymers and other necessary raw materials. Our resin cast current transformers can be used for both indoor and outdoor usage. For indoor usage, they are placed inside panels or cubicles which are known as indoor metering cubicles.

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.

The resin cast PTs are normally used fo indoor application inside the panels.The  resign cas PTs cab be used for outdoor application also provided it is enclosed in hermetically sealed metal tank.
