Encapsulated Current Transformer
Current transformers step down high electrical currents into a lower, more manageable value that can be accurately measured.encapsulated current transformer They are essential for electricity metering and protective relaying, among other uses. They allow you to monitor the amount of power being used and help you keep your energy consumption down, which is ideal for businesses that rely on accurate information to control costs and reduce waste. They also protect equipment and personnel from excessive exposure to harmful electrical currents.
Until recently, however, current transformers were only available as bulky units that required a separate mounting device to be secured to a conductor’s surface. This was not only inconvenient but could result in damage to the conductor and potential injuries to employees. Fortunately, advances in technology now make it possible to use an encapsulated current transformer. As explained in this article, these devices provide a safe and convenient way to measure current in three-phase systems without disrupting the electrical system or requiring invasive installation.
An encapsulated current transformer is an instrument transformer comprising a magnetic core and coil assembly surrounded by a thin layer of insulating material, such as plastic. In one embodiment, the insulating material comprises an injection-molded polyolefin resin. The magnetic core and coil assembly includes a primary winding disposed on a permanent spacer, which in turn is disposed on a winding spool. The primary and secondary windings are connected to first and second terminals via a secondary terminal assembly. The insulating material surrounds the entire magnetic core and coil assembly, including the windings.
The insulating material contains an additive that prevents the secondary winding from wrapping around the magnetic core and thus shorting out to ground. The insulating material also keeps the insulation space between the primary and secondary windings constant even at the high pressures associated with the injection molding process. In contrast to rod-like spacers utilized in prior art current transformers, which were subjected to the same high pressures during injection molding but failed to maintain a consistent insulation clearance between the primary and secondary windings, the permanent spacers and the winding spool of the present invention soften within the normal processing temperature range and amalgamate with the insulating material, thus preventing the formation of an interface between them and providing increased dielectric strength between the primary and secondary windings.
Split-Core and Rogowski Coil Models for Flexible Installation
Whether you need to monitor current in a single phase or three-phase system, Eastron Europe has an encapsulated current transformer that can meet your specific requirements. These devices are versatile enough for use in temporary monitoring or as part of a permanent setup and ensure accurate energy measurements over long periods, offering the highest levels of stability.
In addition, split-core and Rogowski coil models offer a non-invasive installation method that can be implemented without disconnecting the existing conductor. This makes them suitable for retrofitting existing systems in commercial and industrial environments. This means that you can improve energy management and savings with minimal disruption to your business operations.
