Truvolt Engineering Co. Pvt. Ltd. is the foremost Current Transformers Manufacturer, Exporter and Supplier in Kolkata, West Bengal. These Current Transformers are greatly appreciated for their accurate functionality and are highly demanded in the market. These Current Transformers are made in accordance to the industry standards and are reasonably priced. Applications Direct measurement of current in high voltage & high current system is not possible because of difficulty in electrical isolation of measuring instruments. It is also not possible to use current flowing through the system directly for protection purpose due to its high value and difficulty in electrical isolation of protective relays. Therefore, Current Transformers are used to step-down the high system current to standard value accurately in proportion to their ratio. Basic Functions of Current Transformer are To reduce the line current to a value, which is suitable for standard measuring instruments, relays, etcTo isolate the measuring instruments, meters, relays etc. From high voltage side of an installationTo protect measuring instrument against short circuit currentsTo sense abnormalities in current and give current signals to protective relays to isolate the defective system Theory A current transformer operates on the principle of balance of Ampere turns in primary and secondary winding. Voltage Es developed across secondary of the current transformer can be represented as ES=ZS x is where Zs is impedance of burden, connection leads and CT secondary. The magnetic flux required to develop voltage Es needs excitation current i.e. this excitation ampere turns are supplied through total primary ampere turns, causing error in the magnetic material. Errors in the current transformer are also non-linear over the current range of 120% to 5%. There are four main factors which determine the capability of current transformer i.e. Insulation Level (Service Voltage)Rated primary currentShort time withstand currentBurden and Accuracy Current Transformer Must Withstand operational voltage and over voltage in the networkWithstand rated primary current in continuous operation without exceeding maximum allowed temperature riseBe capable to sustain thermal and mechanical stresses developed due to system fault currentFeed current to external circuit with specified accuracy at specified primary currents Design We manufacture current transformers in both types i.e. Live Tank Design and Dead Tank Design. Current transformer can be designed for single ratio or multi ratio. The ratio selection can be achieved by providing two or four sections of primary for series/parallel reconnection. However, the current ratio shall be in proportion of 1:2:4 the advantage of this type of ratio selection ratio. Ratio selection is also possible by giving taps on the secondary winding. Advantage of this type is that ratio can be achieved in any multiple of the lowest ratio. It is also possible to change the ratio on CT without taking shut down on the man system. However, it is obvious that output rating shall change as per the ratio. For multi ratio CT, 2 or 3 ratios can be provided by primary series-Parallel reconnection and additional ratios by secondary taps. High output (Burden/Knee point Voltage / Accuracy Limiting Voltage) with minimum excitation current and better accuracy class can be provided on the CT if primary current is higher. Higher output can also be obtained with multi-turn primary design. Limitations on no. of primary turns are, however, imposed by short time current rating and peak dynamic current. It is advisable to provide minimum primary turns to limit the dynamic forces and mechanical stress experienced by the CT under fault conditions. Construction Core & Secondary Winding: High permeability, CRGO silicon steel is used as core material. Toroidal core from continuous strips are annealed in controlled atmosphere to achieve best quality secondary cores. Secondary winding is done on automatic winding machine and is distributed equally on the periphery of the core to minimize leakage reactance. Best quality enameled copper wire with adequate inter-layer insulation is provided to avoid secondary winding short circuiting in most adverse condition. Primary Winding Primary winding is of braided electrolytic copper conductor with double cotton covering. Varnished fiberglass sleeve is provided as an additional insulation on this conductor. In case of live tank construction, the primary is wound on insulated secondary. The primary is positioned property to sustain dynamic forces developed during short circuit condition. In case of Dead Tank construction, the primary is encapsulated in circular rigid fibre glass ring and galvanized pipe to form Eye Bolt construction. Insulation High quality crepe insulating paper is used to build up main insulation of the CT in live tank design, insulation is built up on secondary core and secondary leads are brought out through a metallic galvanized pipe. In dead Tank CT primary winding is encapsulated in fibre glass ring and Aluminium pipe. Main insulation is built up on primary winding (paper condenser is formed on the pipe) with fine grading of insulation. Semi-conducting shield is used to give linear distribution of Electric stress along the length of the bushing, the paper insulation is dried in oven under very high vacuum and strictly controlled conditions. Filtered and de-aerated EHV Grade oil is filled in CT while CT is under vacuum. To seal it, the space left for expansion on the top is filled with dry and pure Nitrogen through non-returnable valve at predetermined pressure. Porcelain Insulator Brown Glazed porcelain bushing with different shed profiles to suit different pollution conditions are use. These Bushings are hollow cylindrical type conforming to IS 5621/IEC & 815. Bushings with Collar at both the ends are clamped using Aluminium Flange, Nitrile and Neoprene Gaskets are used at both sides of collar to form flexible joint. This joint can sustain vibrations without damaging bushing. Bushings with cemented flanges are also used. Tank & Base Top tank (which also acts as oil Expansion Chamber) of the CT having current less than 800 Amps is made of MS sheet. Stainless steel Tanks is used for CTS with primary current of 800 Amps. And above Base is fabricated from MS plates and channels all MS Tanks and Bases are painted with oven baked paint, after cleaning by seven tank process. All surfaces which come in contact with oil are painted with oil Insoluble Paint. All MS parts can be supplied Hot Dip Galvanized on request. Testing Our testing Lab is equipped with modern test facilities to carry out all routine tests including temperature rise test. Partial Discharge test plays vital role in quality control of insulation. All our Cts are tested for Partial Discharge on most modern bridge type Partial Discharge Test Set. All the Cts pass through a standardized quality assurance plan to ensure requisite top quality at every stage and in the final product. Packing & Transportation All Cts are packed with strong jungle wood to take care of most adverse conditions of transportation all over the country. Special Seaworthy packing is done for the Cts for Export. Maintenance The Cts do not require maintenance apart from occasional cleaning of Bushings and checking of Nitrogen Pressure.

As is well known the Transformer plays an important role in the generation, transmission and distribution of electrical energy. Under load the transformer, dissipates heat and the insulating oil acts as a coolant as well as a effective dielectric. Due to the highly hygroscopic nature of the transformer oil, it absorbs moisture from windings, which leads to gradual deterioration of dielectric strength. TRUHEAT oil purifier is the most efficient and economical purification system

We are offering control transformers. Control transformer is a transformer which supplies power to control and / or auxiliary equipment not intended for direct connection to the main source. Control transformers are specifically used to provide control supply voltage for the control circuits of ac motor starters, i.e. Starter coils, timers, indicating lamps electronics protection relays etc. Control transformers for contractor applications have to energize the coil and maintain a contact for definite period of time. The initial energizing of the coil takes 5 to 40 mil. Seconds and requires 3 to 10 times the normal current. While calculating the va rating of the control transformer, this factor should be taken in to account. They are available for single phase and three phase inputs and are in the range from 15 va to 30 kva. construction control transformers are two winding transformers with both windings made of copper. Power house transformers are made of using high quality materials. Electrolytic grade super enameled wire with best insulations are used. Core material are crgo ei or strip cores.
