There are many different passive types of parts in an electronic system. These parts and components are essential in managing the current through the system and also for current monitoring.
One of the most effective and efficient options for current monitoring is the toroidal current transformer. The electrical component is named for the shape, with the toroidal or donut-shaped core forming the basis of the design. Around this core are the windings, which are configured to provide the specific requirements for the system, device, equipment, or machine.
Use of the Toroidal Transformer
The shape of the toroidal current transformer is a critical factor in the efficiency of this part. It is small, compact, and durable, but also allows for a wide range of mounting and positioning options within a system. Their small size does not impact the ability to monitor and manage large current or high voltage types of applications.
The design of the toroidal current transformer typically includes one winding. However, this winding is very compact, offering what is known as a high turns configuration. This allows for the single winding to have the same function as a primary and secondary winding used on other options in current transformer designs.
Various manufacturers provide different techniques in protecting the current transformer. This can include the use of polycarbonate cases or the use in insulting tape and poly resins. Each of these options builds in durability and increases the life cycle of these components, adding to the return on investment with custom designs of toroidal transformers.
Most of the toroidal transformers produced for OEMs are based on the needs of the company, but they should also meet all industry standards and requirements. In general, the transformers should be UL and CSA approved and recognized, and they need to be RoHS compliant for export and for sale in several states within the USA.
