Reliable Solution Suitable for All Your Needs with ENTES Current Transformers

As it is known, electric current is the movement of particles carrying electrical charge from one point to another. Electrical energy is carried by electrons moving inside conductive cables. Measuring the current is of great importance during the transportation of electricity and at this stage the current transformer comes into play. Current transformers are measurement transformers used to measure the current passing through the circuit. Direct measurement of high currents by measuring instruments is not only costly but also sometimes quite dangerous and difficult.

What is a Current Transformer?

current transformerthe current in the circuit to which they are connected reaches certain values. by reducingrequired for measurement to measuring instruments connected to the secondary (Generally 1A and 5A) current And isolation It is a measurement transformer that providescommissioning sherry Current transformers connected as primary current and secondary current under normal operating conditions. phase difference One of its most important features is that it is approximately zero.

current transformersespecially middle and high voltage The current in the primary in the circuits magnetic By reducing the size with a coupling, a smaller current is obtained on the secondary side, and this current prevents the devices and measuring instruments connected to the secondary side of the machine from being affected by high voltage.

“Current transformers are a type of measurement transformer that is connected in series to the circuit to which it is connected and isolates the devices and measuring instruments in the secondary circuit against high voltage.”

In the structure of a current transformer; primary and secondary windings, a magnetic core, insulators and in current transformers whose cooling type is oil type transformer oil There is a full cauldron.

As in the working principle of a normal transformer; coming to the primary winding alternating currentthis induces a voltage in the winding and creates magnetic flux. With the help of the magnetic core, the flux created by the primary winding is transmitted to the secondary winding. The varying alternating flux causes a voltage to be induced in the secondary winding, and this voltage causes a current to flow in the secondary circuit of the transformer.

In current transformers, the current flowing through the primary conversion rate It is transmitted to the secondary via magnetic path. Since there is high voltage in the primary windings, the windings thick and less winding, Since there are smaller voltages in the secondary windings, the windings are more It is thin and very winding.One of the most important features of current transformers is that their secondary circuit operates in case of short circuit. If secondary winding ends If left open, it causes the magnetic flux created by the secondary windings, which reduces the magnetic flux of the primary windings, to disappear. In this case, the secondary winding ends left open an extreme tension occurs and this causes the windings and core to heat up. Again, in this case, more voltage is induced at the secondary terminals and devices and measuring instruments may be damaged. Therefore, the secondary terminals must be short-circuited.

In current transformers, their secondary ends are short-circuited.

In addition, the secondary ends of current transformers must be grounding is required. The reason for this is a possible fault that may occur between the primary winding and the secondary winding. short circuit In this case, the high voltage in the primary winding completes itself through the ground in the secondary circuit. If the secondary end of the transformer is not grounded, the high voltage in the primary will damage all devices and measuring instruments connected to the secondary circuit in the short circuit between the primary and secondary windings.

The main point to consider when choosing a current transformer is the type of product. To give an example;

► MV compatible current transformers It is generally used at medium voltage values. At the same time, these products are used with reactive power control relays. Thanks to the advanced insulation level, current measurement is made from the MV side by mounting the XLPE cables on the primary side of the medium voltage power transformer. Places of Use: Electricity meters are enterprises located at the entrance of the MV power transformer.

► Another product is low voltage current transformersis. The mentioned products are connected in series to the circuit. These two types are preferred by many businesses due to the advantages they offer.

► Current transformers with separable cores They are generally used in already operating systems because they can be easily installed without separating the busbar or conductors. If there are installation problems in the working environment and the product needs to be reinstalled after being removed, this product type can be selected.

► In cases where installation is desired without cutting off the energy in the panels, clamp type separable current transformers may be preferred. Clamp type separable current transformers are Plug&meter compatible.
