Product Description

By keeping track with market development, we manufacture and export high quality Precise Current Transformers. Offered transformers are precisely manufactured by our skilled technocrats by utilizing premium quality materials. These transformers are designed to measure AC Current. These are also used extensively for measuring current and monitoring the operation of the power grid. Use of latest quality materials which helps in excessive of voltage changes and over load protection, which are suitable for commercial and heavy industrial applications. Further, these Precise Current Transformers are available with us in various standards and custom made designs according to the different requirements of clients.

Features:

  • Accurate functioning
  • Energy efficient
  • Reliable operation
  • Linear output current
  • Design for single-phase intelligence power meter
  • Good consistency, small in size high precision.
  • Casted by flam retardant plastic
  • Packaged by epoxy resin, moisture-proof and quake-proof
  • Easy fixing inside, there are standard orifices at the primary winding, screwed on the bottom case
  • Regular P/N and dimensions

Working Principal:

The basic structure of current transformer(CT) is comprised by primary winding, secondary winding and iron core, among which strong insulation is set between the primary, secondary and iron core.

The function of CT in Energy Meter is to transfer the large current I1(A)in metering circuit to the small current I2(mA), then I2 in series with the sample resistor R is converted to voltage signal (I2*R) which is connected to chip in Energy Meter.

Our miniature CT is produced in comply with JB/T10665-2006 Miniature current transformer GB 1208-2006 current transformer standard and JJG 313-2010 current transformer for measurement requirement.

  • Dielectric strength at power frequency the rated power frequency withstand voltage between the primary and the secondary is 3kV root-mean-square value , especially 4kVroot-mean-square value when the insulation requirement is Class under the test condition according to GB/T17215.
  • Interturn dielectric strength when the secondary winding open, the primary winding is stimulated by 40 60Hz true sine wave current, whose root-mean-square value equals the rated primary current, the inter-turn insulation is free of damage during 60s continuous stimulus.
  • Insulation resistance the insulation resistance between the primary versus the secondary versus the ground is larger than 600M
  • Polarity the CT has subtractive polarity, that is, when the current in the primary flow in from Port P1, the current in the secondary flow out from Port
  • Overload capacity with the rated load, CT who survives after current strike of a 30*Imax for one half period, shows his error not more than the required limit by 1.3 times stimulated by rated current, and satisfies the accuracy class requirement after degaussing.
  • Error limit With the rated load or with the listed value load, the current error (ratio error) and phase error (angular difference) should not exceed the regulated limit.

Environment requirement

  • Temperature -25 +75 relative humidity not more than95%25 attitude not higher than 1000m
  • Rated voltage 600Vsine wave distortion factor less than 5%
  • Not serious pollution in the air;
  • Not serious shake;
  • Far away from the irrelative strong electromagnetic field

Store requirement

  • Stored indoor at temperature -25 +60, relative humidity not more than95%25 .
  • Far away from corrosive hazardous substance and rain and snow.

Select and use
CT should run at rated current long time, and the maxim work current should not be more than the nominal maximum current rated load is the maxim load at this accuracy class.
