A current transformer (CT) is a type of transformer that is used to measure AC current. It produces an alternating current (AC) in its secondary which is proportional to the AC current in its primary. Current transformers, along with voltage or potential transformers are Instrument transformer.

Current transformers are named using the Magnetization current can be defined as “the portion of the no-load current that is used to establish flux in the core of a transformer“. It is generally denoted by the letter I m . Generally, when a transformer is energized under no-load conditions, it draws a small amount of current. If turn-on occurs when the AC voltage wave is at its peak value, there will be no inrush current drawn by the transformer. The magnitude of the current in this case will be at normal no load value. If at turn-on, the AC wave is going through its zero value, then the current drawn will be very high and exceed the saturation current (see Figure 1).

Instrument Transformers, Inc. 5-34.5 kV Class Current Transformers. Cable/Bus-bar type current transformer with DIN-rail/bus- bar and panel mounting facili- ty. Rated primary currents from 40 A to 600 A. Accessories.

Traditionally, current transformers have been designed with a standard secondary current of 5 Amps which is used with conventional analog instruments and meters. Many control designs still utilize this standard concept which in many cases necessitates a mechanically larger unit than needed when hooked up to an op-amp or similar electronic circuits.

Model 2 series of current transformers has a 1.13" diameter window size and a 600V, 10 kV BIL insulation class. And with the 50-300 Amp current range, these 27 Sep 2019 What is a current transformer (CT)?

In high power circuits, the voltage across the primary side is scaled down to a minimum value, which helps to measure the actual AC Example: Both current transformers have a transformer ratio of 1,000/5A. The total measurement is carried out using a summation current transformer 5+5 / 5 A. The UMG must then be set up as follows: Primary current: 1,000 A + 1,000 A = 2,000 A. Secondary current: 5 A. Current transformers and accessories Obviously currents of several hundreds to thousands of Ampere cannot be directly digitally measured. Current transformers convert almost any amount of primary current into “bite-sized” secondary currents.

Les choristes summary

The current transformer is used with its primary winding connected in series with line carrying the current to be measured and, therefore, the primary current is dependant upon the load connected to the system and is not determined by the load (burden) connected on the secondary winding of the current transformer. AIRUIFA® - Distinguished by OEM Current Transformer, Panel meter, Shunt ,and Sourcing products.

Current Transformers in Power Protection System– A Protection Current Transformer is used to reduce the currents in power systems thereby protecting it from faults. These Current Transformers measure the actual current in the primary side and produce proportionate currents in their secondary windings which are completely isolated from the A current transformer is a device that is used for the transformation of current from a higher value to a lower value.

The SCT current transformers allow reliable power sensor technology to be implemented directly in the field as an integral part of the PC-based control system. Users can choose between two concepts, which are highly scalable thanks to various designs and performance classes and are thus suitable for any application.
