The Arrangement & Types of Current Transformers

The primary winding of a current transformer is only one or a few turns long. This primary winding can be as simple as a bus bar or conductor position through a central hole, or it can be as complex as a coil of heavy-duty wire coiled around the core. Elmex Control Pvt. Ltd. offers a wide range of Ring Type Current Transformers.

The Arrangement:

Because of the configuration of this current transformer, it is frequently referred to as a series transformer. The primary winding, which has only a few turns, is connected in series with the current transporting the conductor that is giving a load.

The secondary winding, on the other hand, might be made up of a large number of turns twisted around a laminated core made of low-loss magnetic material. The magnetic flux density created with a big cross-sectional area of the core is on the low side, utilizing a smaller cross-sectional wire area, depending on the amount of current that must be stepped down as it seeks to push out a constant current, apart from the linked load involved.

The secondary winding sends a current either to an inter-resistive load or to a short circuit in the form of an ammeter until the voltage generated in the secondary is large enough to cause failure owing to excessive voltage breakdown or to saturate the core.

Standard types of Current Transformers: - Toroidal Current Transformer:

These transformers lack a primary winding. The line that transfers the network's current flows via a hole or window in the current transformer. Some of these current transformers include a split core, allowing them to be opened, placed, and closed without disconnecting the circuit to which they are connected.

• Wound Current Transformer:

This transformer's primary winding is physically connected in series with the conductor that delivers the measured current flowing through the circuit. The magnitude of the secondary current is proportional to the current transformer's turn ratio.

• Bar-type Current Transformer:

This current transformer's primary winding is the actual busbar or cable of the main circuit, which is equivalent to a single turn. These transformers are totally insulated from the system's high working voltage and are frequently bolted to the device delivering the current.
