HT AVR

ELDEE makes Transformers with built-in HT Automatic Voltage Regulator is a revolutionary Landmark in the Industry when it comes to voltage Regulation and Stabilization.Even after the installation of standard distribution transformers the problme of Low / High Voltage on the LT site remains,resulting in improper operation of the electrical machines of a plant.The standard off-circuit tappings of the transformers can correct limited voltage variations and cannot regulate the voltage while in 'on load' condition.Thus,the R&D team at ELDEE developed a smart" way of tackling the problem with Transformers having Built-in HT Automatic Voltage Regulator that operates on load,steplessly. The equipment is basically a combination of HT AVR with a standard distribution Transformer.The fluctuating voltage from'Grid'is initially stabilized by the HT AVR and then fed to the transformer resulting in the constant L.T. Output within + 1% accuracyand the Biggest advantage being the robust design of the equipment which does not demand regular maintenance. Advantages of transformer with built in HTAVR : • Better Efficiency • Reduced Installation Cost • Space Saving • Energy Saving • Protection of Motors • Reduction in Electricity Bill • Low replacement cost Specification : • Capacity : Upto 5000KVA • Input Voltage : 8.5 KV=12 KV =3Phase • Output Voltage : 11KV + 1% - HT -3Phase 415 + 1% - LT - 3Phase Technical Advantages of ELDEE Voltage Regulators : • Low replacement cost • Undistorted output characteristics i.e. no wave from distortion. • No Moving Parts On L.T.site and it's mass is extremely low. • Energy Saving • High efficiency (approx.99%) and minimum no-load losses. • Simplicity and Flexibility of design. • On load stepless Voltage Variation • Long service life • Impulse Tested • Regulating coils are wound with rectangular conductors on their edge,thus giving high mechanical strength compared to other designs.

solation Transformers

Any transformer,single or three phase in which primary and secondary are separately wound (double wound) is an isolation transformer as primary and secondary are internally isolated from each other.The power transfer at rated frequency is by transformer action through mutual inductance. The Modern machines and systems need a truly is olated clean power in which any electrical disturbance in the priary side is effectively not passed on to secondary side. Therefore an Isolation/Ultra Isolation transformer ensures total electrical and electro satatic isolation local neutral and dedicated earth which are very essential for modern machines.It provides noise or interference free power and prevents transfer & RF and HF disturbances with extensive isolation between primary and secondary.The isolation level with stand HV break down strength of 2.5KV and gives DC galvanic isolation of more than 1000M Ohms.

Servo Voltage Stabilizer

Continuous stable supply of A.C Power is the life line of any sophisticated electronic and electrical system. The performance of these instruments is optimum at the rated voltage. Under voltage generally reduces efficiency,and very low voltage even can force the system to shut down. High voltage shortens the life and even can burn the instruments. ELDEE Servo Voltage stabilizers receive fluctuating AC Voltage of wide range and delivers constant output voltage with ± 1% of the nominal voltage ; it is therefore an excellent remedy for the problems of wide voltage fluctuation.The efficiency is maintained as high as 98-99%.The output voltage stability of our servo stabilizer allows the optimum drawing of the current by the connected load and as such no extra power is consumed at low as well at high voltage.This therefore saves electric power to approximately 20% and reduces MDI(Monthly Demand Index). SVS (servo voltage stabilizer) basically comprises of Auto Transformer (Dimmer State/Roller Contact type) coupled with A.C.Servo Motor, Buck Bust transformer Control card for regulation All these components are interconnected adequately to accomplish the work of stabilization of output voltage of SVS. Use of reliable high quality components alongwith microprocessor controlled circuitry ensures the operation of our Servo Stabilizers flawless.

Quality Policy Quality Assurances an important part of the company's policy and confirming to the IS 2026, BS 171, IEC76, IS11171, IEC 726, & IS 9815 (As Applicable). Product Range We are one of the experienced manufacturer as well as repairer of all special type Transformers from 10 KV A to 5000 KV A in class and servo voltage Transformers. Construction of Product : Core The core is constructed from lamination of Cold Rolled Grain Oriented, low loss electrical sheet steel confirming to the latest International Standard which define its physical characteristics such as freedom from scale, degree of waviness, brittleness, tolerance on thickness, the inherent loss due to hysteretic and eddy currents, the permeability, and the methods to be employed to ensure compliance with lhe specification. Each lamination is coated with both sides with insulation which is unaffected by continuous operation in oil at temperatures normally experienced in Transformer service. The core, which is of interleaved construction, with mitered joint to reduce iron loss and magnetizing current, is designed to have a uniform flux distribution throughout the magnetic circuit. Winding Transformer winding are designed to meet three fundamental Requirements: mechanical, thermal and electrical. They are cylindrical in shape and are assembled concentrically. Paper insulated conductors of high conductivity soft drawn copper used, comply with the latest Indian Standard, both HV & LV winding are wound with adequate bracing and securing tapes in order to accieve a strong, self support structure. Insulation between layers and turns is based upon the impulse test level of the voltage class of winding as specified in IS 2026. Tappings Tapping are brought away from the winding by means of flexible conductors, heavily insulated with paper, and supported by insulated tubes or cleats to prevent movement under service conditions. Tank Construction All tank are fabricated from mild steel which is electrically welded, cooling radiators are welded or detachable depending on the size of the transformers. The cooling radiators are of pressed steel, electrically welded. AII tanks are pressure tested before leaving the fabrication shop of factory. Ovening The ovening of the transformer is carried out in well ventilated, electrically heated ovens for a period determined by electrical testes. The transformer is then fitted with dehydration oil confirming to I S 335. Tests Before dispatch, all transformers are subjected to routine tests in accordance with IS: 2026, or to such tests as the customers specification requires. Benefits Energy Saving under non-liner loads: Pollution of power systems is due to injection of harmonics under non-liner condition. These condition are found in case of pumping application, industrial application like thyrister drives, are furnaces etc. Under such environment will have 5 time greater energy saving than CRGO core transformer. Energy Saving The no load loss is a continuous loss taking place after energisation during the period of operation. In case of amorphous core transformer, no load losses are reduced by 75% when compared with conventional transformer. If we compared the marginally higher initial one pays with saving in the electricity bills, the pay beck in majority of the cases will not exceed 2/3 years. Annual energy savings (Rs) = (NLL of CRGO – NLL of AMT) in Kw x 24(hrs) x 365 (days) x 4.5 per Khw
