Variable Auto Transformer

Variable Auto Transformer (VARIVOLT) AUTO TRANSFORMER is a continuously variable voltage auto transformer, having a movable carbon tip, fixed to brush arm sliding on a silver plated commutator. Rotation of the brush arm by either manual or motor drive, Auto Trelivers an output voltage from zero to or above line voltage. "VARIVOLT"conforms to I.S. 5142.


Salient Features :

  • Rugged Construction : "VARIVOLT" Auto transformers are designed for heavy duty trouble free operation. All components are designed to give maximum life to the unit under extreme operating conditions. Except for carbon tips, no other part needs any specific maintenance. Even carbon tips do not require to be changed frequently. This practically makes the “VARIVOLT" a maintenance free electrical equipment.
  • Excellent Regulation : The drop in voltage from “no load to full load” is minimal in "VARIVOLT" Auto-transformers. (See fig...II for regulation characteristics)
  • High Efficiency : Careful copper, core selection and design assures the user of low watt loss, as compared to other controllers.
  • No Wave form Distortion : "VARIVOLT" provides an output voltage wave-form, which is a distortionless replica of the input voltage wave-form.
  • Silver Plated Commutator : A special silver plating technique is used on the commutator, enabling it to withstand high overloads and maintain constant contact drop. It also ensures smooth operation, long life and increased resistance to corrosion.
  • Over-load Capacity : Because of its careful designing, “VARIVOLT” can withstand many over-loads, Fig. 1 gives an idea of the maximum overloading allowed with its relevant time limits. When repeated overloading takes place, care has to be exercised to provide sufficient off time to reduce the temperature build up.
  • Low Operating Torque: A glass smooth commutator, special sintered bushings for the shaft and perfect assembling of coils results in low operating torque for all "VARIVOLT" Auto-transformers.
  • Smooth and Linear Output: As voltage between turns is small and as the brush arms is in constant contact with more than one turn, harmful sparking avoided and output voltage can be set to a fraction of a volt from zero onwards.

          Construction Of Tape Wound/Resin Cast Current Transformers

          Voltamp Current Transformers are made from high magnetic performance prime C. R. G. O. Silicon Electrical Steel. The performance of the core is checked to meet final parameters such as ratio, rating and accuracy. The current transformer is finally completed by placing PVC washers on top and bottom and then taped closely with polyester film and polyvinyl chloride tape. Proper lugs are provided on secondary terminals with S1 and S2 markings. For resin cast ct's wound ct is moulded in epoxy/polyester resin. Anodised/Printed name plate slipped within outer tape mentioning specifications and P1, P2 direction.


          Applications:

          Suitable for Ammeters, Wattmeters, Power Factor meters and Protective Relays. In addition to the above we can offer current transformers to your requirement with various combinations of ratios, burden accuracy class and type subject to technical feasibility.

          Suggested Burden Guide :

          • Moving Iron Ammeters 1. 5 VA to 5 VA
          • Recording Ammeters 2 VA to 10 VA
          • Recording Thermal Demand Wattmeters 0. 7 VA to 1. 4 VA
          • KWH Meters 0. 3 VA to 0. 6 VA
          • Thermal Demand Ammeters 3 VA
          • Thermal Maximum Demand Ammeters 4 VA to 8 VA
          • Cable 7/029 5 AMP secondary 0. 05 VA/ft
          • Cable 7/029 1 AMP secondary 0. 002 VA/ft

          Directions For Use:

          • The secondary circuit of the transformer must be grounded. Make sure that secondary circuit is never opened while current is flowing in primary windings, otherwise dangerous high voltage will result. The grounding of secondary circuit eliminates error due to accumulation of electrostatic charges on the instrument
          • Secondary winding should he short circuited end the line voltage should be cut when changing instruments or when not in use
          • For the primary winding, to which the line of voltage is directly applied, use a wire insulated well enough to withstand the specified maximum line voltage
