Current Transformer

We are one of the renowned manufacturers, trader and exporter of a wide assortment of Current Transformer with economic limit of 100/5, 5VA, CI: 1.0 or 200/5, 15VA, CI: 1.0. Using finest quality raw materials, we manufacture these transformers in our sophisticated production unit. Our stringent international quality tests guarantees perfect performance and low maintenance. 

  • Low cost and convenient form of CT is a Bar or Ring type, popularly called BPL Low ratio CTs require high accuracy or high burdens cannot be constructed in BPL type. The economic limit is 100/5, 5VA, CI:1.0 or 200/5, 15VA, CI:1.0. In case of lower ratio either the burden goes lower or accuracy lower. When high accuracies and or high burdens are called for, only solutions are a WPL CTs. A WPL CT is costlier and cumbersome in use too.

Indoor Ring Type CT

Approx. Price: Rs 1,500 / PieceGet Latest Price
Product Details:
Winding Number2 ( Primary and Secondary )
Magnetic permeabilityYes
Core TypeIndoor

Our company provides superior Indoor Ring Type CT in the market. A varying current in the transformer's primary winding creates a varying magnetic flux in the core and a varying magnetic field impinging on the secondary winding. This varying magnetic field at the secondary induces a varying electromotive force (EMF) or voltage in the secondary winding. The primary and secondary windings are wrapped around a core of infinitely high magnetic permeability so that all of the magnetic flux passes through both the primary and secondary windings.

 

Features:

 

  • Trouble free usage
  • Negligible maintenance
  • No wear and tear of the parts

Product Details:
CT Ratioerror less than _+0.25%
Maximum fault currentCT point
Winding Number2

Our company is one of the renowned name of PS Class CT. These are high accuracy class electrical devices used to isolate or transform voltage or current levels. The most common usage of instrument transformers is to operate instruments or metering from high voltage or high current circuits, safely isolating secondary control circuitry from the high voltages or currents. The primary winding of the transformer is connected to the high voltage or high current circuit, and the meter or relay is connected to the secondary circuit.

 

Features:

 

  • High current circuit
  • Negligible load to the supply
  • Highly durable

PS CTs are specified by:

  • Turn ratio (error less than _+0.25%)
  • Minimum knee point voltage (Vk)
  • Maximum exciting current at Vk or at its fraction
  • Maximum resistance of secondary winding
  • In case Vk is not known, following information may be given
  • Tech. specs of the relay to be used and relay set current
  • Scheme of protection where CTs are to be used
  • Maximum fault current of the system at CT point

Resin Cast CT

Approx. Price: Rs 650 / PieceGet Latest Price
Product Details:
Flame retardantYes
Shock and vibration proofYes
Core TypeResin Cast CT

In the field of current transformers, our company offers supreme quality Resin Cast CT. They are designed to present negligible load to the supply being measured and have an accurate current ratio and phase relationship to enable accurate secondary connected metering. These are constructed by passing a single primary turn (either an insulated cable or an uninsulated bus bar) through a well-insulated toroidal core wrapped with many turns of wire. This affords easy implementation and using the pass-through conductor as a single turn primary.

 

Features:

 

  • Easy implementation on high voltage bushings
  • Secondary turn core
  • Long operational life

Other Details:

  • Hermetically sealed to impart flawless performance even in polluted & corrosive atmosphere
  • Perfectly finished in charming colours

Class CT

Approx. Price: Rs 750 / PieceGet Latest Price
Product Details:
Core TypeClass CT
PhaseSingle Phase
Cooling typeLiquid (oil )

We are a known name of Class CT. These are designed with smaller cores and VA capacities than power transformers. This causes metering power transformers to saturate at lower secondary voltage outputs saving sensitive connected metering devices from damaging large voltage spikes found in grid disturbances. They are designed to present negligible load to the supply being measured and have an accurate voltage ratio and phase relationship to enable accurate secondary connected metering.

 

Features:

 

  • Wire-wound
  • High operability
  • Capacity of extra high voltage
