Current Transformer

Product Details:

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

• 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

Product Details:

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

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

• Core 1: 1A, metering, 15 VA / class 1, ISF<10
• Core 2: 1 A, protection, 15 VA/5P10
• Core 3: 0.577 A, Class PS, KPV>=150V, Imag at Vk/2 <=30 mA, RCT at 75 C<=2 ohms
• Insulation level voltage (ILV): 12 / 28 / 75 KV
• Ratio : 200/1 – 1 – 0.577 A

Product Details:

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

Product Details:

Our company has been dedicatedly providing Summation Current Transformer. These transform high currents and voltages to standardized low and easily measurable values that are isolated from the high voltage. When used for metering purposes, instrument transformers provide voltage or current signals that are very accurate representations of the transmission line values in both magnitude and phase. These signals allow accurate determination of revenue billing. When used for protection purposes, the instrument transformer outputs must accurately represent the transmission line values during both steady-state and transient conditions. These critical signals provide the basis for circuit-breaker operation under fault conditions, and as such are fundamental to network reliability and security.

Features:

• Accurate determination of values
• Smooth functioning
• Multiple indicators

Product Details:

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
