An isolation transformer is a device which is used to decouple two circuits, the load connected to the output of Isolation transformer and to the input supply. Isolation transformer suppresses electrical noises which occur in the Transmission line, because of the other loads connected in parallel. Shakti isolation transformer provided with Electromagnetic & Electrostatic shielding block transmission of DC signals from one Circuit to other but allows AC signal to transmit. It also prevents interference caused by ground loop.   Few Features of Shakti Isolation Transformer are:   Isolation of primary winding and secondary windings. Electromagnetic & Electrostatic shielding. Very Low Coupling Capacitance. Provide isolated neutral. Protects micro processor based equipment from dangerous noises and reduces failures. Can be useful where machine earth can’t be used. By Providing Delta star isolation transformer in 3-ph models, the problem of earth or neutral in the input side is taken care for the safe operation of the load. It arrest the noises of high frequency and noises generated by the usage of high current MCB, ACB, Induction furnace or other electro magnetic noises.

All these transformers are designed, manufactured and supplied against specific requirement of supply voltage for the equipment. e.g. Equipments imported from American Countries work on supply voltage of 110/120 V, 1-Ph or 200/220 V, 3-Ph. Depending upon the type of equipment, Step up/ step down transformers can be supplied in both auto wound type or isolated type.  Similarly step up or booster transformers are supplied for the areas, where the supply voltage is usually very low.

3-Phase Linear/Roller Types Servo Regulator We are manufacturing Industrial type Automatic Voltage Regulators (Stabilizers) using the differential wound Vertical Roller Type Regulators.LINEAR TYPE Plus/Minus Heavy Duty Regulator is manufactured with rollers rolling on both the sides of the coil. The size of conductor used is much more than that used in conventional design regulators. Being +/- type, the same winding is used for boosting the voltage on one side and bucking the voltage on the other side of the regulator. So the rating of the regulator required is much less than that of the conventional design regulator. The losses of differential wound linear regulator are lesser than the conventional type regulator and due to heavy section of copper used in our regulator, overall size is more and practically the losses of our regulator are much more lesser than the conventional type of regulator. As per the Regulator design, the regulator is technically OUT OF CIRCUIT, when the input voltage is LOWEST/HIGHEST as per the voltage range of the stabilizer while in stabilizer with conventional brush type regulators, the regulator is in the circuit and losses are maximum at LOWEST/HIGHEST voltage as per the range of the stabilizer. QUALITY: CORE:  The core is constructed from low loss, cold rolled, grain oriented, annealed laminations of electrical sheet steel conforming to the latest standards using grade M4 laminations for the minimum no load losses. WINDINGS:  Regulator Coils are wounded with 4PC paper layer covered copper strip for better insulation. The X-section area of the Electrolytic Grade copper strip used is much higher to give highest quality with minimum losses for the entire running life of the equipment. RADIATORS:  Cooling is provided to keep the hot spot temperature as low as possible for higher working efficiency and for all the years with lowest temperature rise even on full load conditions. TANKS & PAINTS:  The enclosure/tanks are made of M.S. steel plates / sheets of 3 mm thickness with adequate stiffeners. All the external and internal surfaces are given a primary coat of Epoxy primer and finishing coat of Epoxy paint for better life. OIL:  Oil is properly tested for resistivity, dielectric and acidic characteristic conforming to IS 335. Before topping up oil is filtered thoroughly. We use HT grade 11 KV oil even for the LT  equipment for better dielectric strength and high flash point.
