Current transformers - Series MT+CT

  • Function:
    When current in a circuit is too high to apply directly to measuring instruments, a current transformer produces a reduced current accurately proportional to the current in the circuit, which can be conveniently connected to measuring and recording instruments.
    A current transformer isolates the measuring instruments from what may be very high Current in the monitored circuit.

  • Applications:
    Current transformers are commonly used in metering.

  • Features:
    Current transformers are used extensively for measuring current. This new CTs range covers every facility with three-phase service and single-phase services greater from 40A to 4000A.
    The CT is typically described by its current ratio from primary to secondary.
    Often, multiple CTs are installed for various uses. For example, protection devices and revenue metering may use separate CTs to provide isolation between metering and protection circuits, and allows current transformers with different characteristics (accuracy, overload performance) to be used for the devices. The primary circuit is largely unaffected by the insertion of the CT. The rated secondary current is commonly standardized at 5A. For example, a 4000:5 CT secondary winding will supply an output current of 5 Amperes when the primary winding current is 4000 A.
    The load, or burden, of the CT should be a low resistance. The accuracy of a CT is directly related to a number of factors including: burden, burden class/saturation class, rating factor, load and physical configuration for the IEC standard, accuracy classes for various types of measurement are set out in IEC 60044-1, Classes 0.5, 1 and 3.The class designation is an approximate measure of the CTs accuracy.
    The ratio (primary to secondary current) error of a Class 1 CT is 1% at rated current; the ratio error of a Class 0.5 CT is 0.5% or less.
